How RFID Tags Can Improve Efficiency

In order to demonstrate how RFID tags can greatly sway the fortunes of a business for the better, we can look at a hypothetical case below. Let us take the example of a furniture maker specializing in the supply furniture to a hotel group.

This may sound like an example with no relevance to normal small businesses, but in fact, hotel chains are extremely choosy and have no loyalty, so if you can please these people, you can please anyone.

The main requirements of the hotel chain are that orders are met and on time, the quality of the supplier’s products has already been considered to be sufficient by means of enforced ISO 9000 quality control and factory visits.

The hotel furniture manufacturer decides to introduce passive RFID tags to follow its items from the point of manufacture to the point of delivery, that is the hotel or its storage area.

Under previous conditions the manufacturer had employed a couple of people to walk around with bar code readers and clip boards carrying out quality control and tracking the completion of orders.

The problem was that the arrangement was still subject to human error and items still went missing, which resulted in management compensating by over manufacturing and over stocking ‘just in case’.

That is a common enough phenomenon., but the difficulties are multiplied when you think of all the separate items of furniture that are implicated in a hotel room, bathroom or lobby and if they are stored in a 200,000 square foot warehouse. Items get lost, forklift drivers make errors, people forget to fill in inventory forms, get sick and take holidays.

In short, running a warehouse like this is a nightmare with too much stress on key employees. It sometimes leads to imperfect deliveries or worse, incomplete delivery tickets. Sometimes the order might be complete but the hotel would think it was not because the delivery ticket was incorrect.

If this company were to initiate RFID asset control they could affix an RFID tag to completed sticks of furniture. The tag would say where it is, what it is, whom it is for, when it has to be delivered and what else makes up part of the order. The tag is being read continuously by the warehouse’s RFID readers forewarning when orders are running late or are still incomplete.

Not only that but the tag can say what else has to be made and whether the object itself has passed quality control. It can also say which defects someone has found with it. In short, instead of a couple of people traipsing around the stockroom hoping that they have covered everything, you could have radio sensors reading every tag in a warehouse the size of a soccer pitch, reporting back to a central computer where the storehouse manager can have access to real time intelligence, not just the state of affairs at close of business the day before.

This should enhance the manager’s chance to manage, cut down on waste, ensure complete orders delivered on time and so higher levels of customer satisfaction, which should lead to more repeat orders.

Radio And Inventory Control By The Use Of RFID

RFID is the recognized acronym for Radio Frequency IDentification. The basis of RFID technology is that every RFID chip or tag is capable of sending a radio signal on a frequency wholly unique to itself.

Therefore, every RFID tag must have its own identifying frequency and the RFID tag readers must be sensitive enough to be able to distinguish between frequencies that are only a very minute bit different from its neighbouring tags. The disparity can be microscopic.

Therefore, the technology has to be sensitive and selective, but not delicate, because the apparatus has to be used on the shop floor and by people who are often in a hurry and in weather that may be inclement.

In order for RFID to work, you need a tag, which is an upmarket kind of bar code and a radio receiver, often called a (tag) reader. However, whereas a bar code can only hold a small amount of information and the bar code reader has to be pointed at it, an RFID tag can store much more information and can be read from a hundred yards or more – even out of line of sight.

Passive tags will only reveal their details when asked to by a reader, whereas an active tag is constantly relaying its contents. Clearly, active RFID tags are more costly than passive tags, because they require a long life battery.

These tags can be utilized to track items from the moment they leave the manufacturer of the goods they describe to the in-bay of the vendor. The tags can then be up-dated or replaced and stored in the warehouse. Once there, RFID readers can keep management informed about what goods are where and if the sell-by-date is impending.

This has implications for the amount of stock that a business needs to hold, the amount of goods sold cheap because the sell-by-date is too near and for theft, all of which should increase company profits more than paying for the cost of the tags, the readers, the printers and the software.

At the click of a mouse, managers will be able to read how much inventory they have in real time and if this is all linked to the checkout cash registers, which are the most and least profitable items. This makes reordering easy . Easy to the point of automation. For instance, when stocks of the top ten percent of the best selling items falls below 1,000 order 10,000 more. Automatically, no questions asked.

RFID has many other applications too. The ideas mentioned above can be applied to farm animals, a call centre’s IT hardware, a fleet of commercial vehicles, an record of household items, your pets, your car and even your garden furniture. Some people who work over a border are even having them put under their skin so that they do not have to wait at customs.

And do not forget that criminals on early discharge are also tagged. It is the same technology.

How To Keep Your Data Safe

Information has always been power and that has not changed. Nowadays people may say that data is power, but the expression means the same. So, if your information or your data is so valuable, how can you keep it private? In other words, how can you safeguard yourself and your savings?

The Internet, viruses, scanners, chips, RFID, credit cards and spyware make the job quite tricky, if a criminal wants to get hold of your data. Regrettably, it is not good enough to hope that a data thief will not pick on you.

Your bank, your insurance company or the government may give your details to them by leaving them on trains, throwing them in skips or leaving them on hard drives in computers that they later sell secondhand on eBay. It occurs several times a year that we hear about, who knows how many times more?

So, what can you do? Well, there are quite a few things that you can do, but the issue is that most people will not apply them until it is too late, hoping that they will not be a victim of data snooping.

The first thing to do is to try to protect your data. That sounds obvious, but how do you do it?

Let’s begin with your written name and address. You could inform your local council that you want to be taken off any lists that they pass on to anybody that asks for them. Likewise, you can have your address taken of the junk mail lists and you can have your phone number taken off the junk phone mail list. Ask your local municipality how to go about this.

You could buy things with a ‘post restante’ address at your local post office. If need be, explain why to the company you are buying from why you are doing that. Or you could have your mail redirected from one address to another.

For example, if you have a lock-up address, use that address, but pay the post office to re-direct your mail to where you wake up every day. Another idea to try is to modify your name. Add in your middle initial, or your full middle name. Add the suffix ’senior’ or ‘junior’ and keep notes. If you get junk mail with these names, you know who to complain to.

You computer probably contains a great deal of sensitive data and you should protect it, not least because some of that data will be the email addresses of your acquaintances and you do not want to introduce them to thieves, do you? Fortunately, this form of protection is comparatively easy.

Make certain that you use a firewall and anti-virus protection. Use the best you can afford. The best will cost about $50-60 a year. At $1 a week, it is not worth being mean. You can get free software to do the task and some of it is pretty good, but how many times do you want to pick the wrong one?

Then there is your purse. RFID tags are installed in most ID cards and credit cards these days and they can be read by the thousands of RFID readers in hotels, hospitals, offices and shops. Think about shielding your wallet, bag or purse or wherever you keep your cards, so that they cannot be read by chance RFID readers.

How Do RFID Cash Registers Work?

The majority of of the newer outlets and the bigger chain stores use RFID cash registers. RFID cash registers are hooked up to an RFID reader which is used to scan the article being bought to obtain the price, record the sale and control the stock. This method of recording the sale makes it quicker at the check out. It also reduces the human error factor.

Radio Frequency Identification or RFID is similar to utilizing bar codes but they can hold a lot more information and they are usually not taken off after purchase, because passive RFID tags can be really small and can be put under labels on cans of food or sewn into clothing at the point of manufacture. Every tag responds in a different frequency, so the items in a shopping trolley do not even have to be removed to be counted, which is the not the situation with bar codes.

It is unlikely that bar codes will disappear any time soon because they are so commonly used, but the fate of bar codes is surely sealed. They will be supplanted. Bar code readers are hand-held, but RFID readers can be in a fixed place, scanning the shopping trolley from about a metre away.

RFID cash registers are bad news for check out clerks, because they can operate far more quickly than conventional cash registers. You will not need to unload items and check out clerks will not have to hold every item and punch in the prices, so there will be no mistakes either.

In the future, stores will only have to have check out clerks for patrons who wish to pay in cash. Most people pay with a credit or debit card nowadays, so all you would need is a RFID cash register and a credit card swiper so that the customers can pay.

A superstore that now provides twenty points of sale with twenty check out clerks, could have eighteen RFID cash registers for those with credit cards and two traditional cash registers for customers paying with cash.

In fact, because RFID cash registers are so much faster, the superstore could most likely do away with five of those points of sale as well without any reduction in service or quality to the clientele.

For the merchant, the cost of installing RFID cash registers is not insubstantial, but the costs will be recovered pretty swiftly by the reduction in wages.

RFID cash registers offer higher levels of stock control than bar code readers because the RFID tag can hold a lot more information than a bar code. Stock control is clearly important, because a merchant neither wants to run out of an article nor have too many of an article tying up money.

RFID cash registers, linked to a computer, can automatically show you which products are selling the most and which items are producing the most profit for you. This makes it simple to order more of the goods at the top of the list and fewer of the items at the bottom.

In fact, even ordering could be automated according to a pre-programmed algorithm. The only possible drawback with RFID cash registers is an interruption in the power supply., but you could reduce that problem by having a support generator.

RFID Tags: General Information

All RFID tags are used to store and ultimately send data. They can best be thought of as the replacement for the bar code. However, they have significant advantages over bar codes. For instance: RFID tags can hold much more data than bar codes; they can be scanned from further away and they can in point of fact send data, not only store data.

There are three varieties of RFID tags: passive, active and hybrid. Passive RFID tags are the least expensive, because they are less complicated. They need to be asked to divulge their data by taking power from an RFID reader. When the reader’s radio waves hit them, they echo back their data. This is the sort of tag used in goods in a retail outlet or on crates in a warehouse.

On the other hand, active RFID tags have a battery, a transmitter and an aerial so that they are always transmitting. These devices are obviously a lot more expensive and so are used only on more expensive items such as a container, a battle tank, an aircraft, on criminals ankle bands or on an animal of an endangered species.

The hybrid RFID tag is capable of transmitting, but it needs to be told to transmit; it has to be turned on by a signal. This signal could be a satellite passing over head. These hybrid RFID tags are also expensive, but the battery lasts longer because they are not ‘always on’. These tags have the same uses as the active tags, but are appropriate for use where it is not critical to know where something is every minute of the day: for instance cattle in a field or goats on a mountain.

Passive tags can be attached permanently by sewing them into linings or putting them under skin because they do not have their own power source and do not wear out. This is a cause of anxiety to some people who worry about an invasion of their privacy or the erosion of their human rights.

Active and hybrid tags are most often clearly visible so that the batteries can be changed as and when necessary. If this is going to be not likely to take place, as in the case of wild animals, the tag can have a biodegradable fastener which will break sometime after the expected expiry of the battery.

Some uses for RFID tags are on season tickets so that the owner can pass through the style more quickly than a customer paying by cash. It has applications in security; most of the ID badges you see pinned to shirts have RFID built into them so that security guards do not have to stop and query everybody.

They can be put into trucks that repeatedly cross frontiers so that they do not have to stop for identification. They can be placed on windscreens so that, as you drive through a motorway toll post, either your credit card is debited or the charge is added to your company’s monthly account.

Hospitals utilize them on patients so that they do not lose anyone or misidentify them. RFID tags are helpful in our daily lives but people are concerned about criminals being able to read all this information too readily as well.

RFID Tags In Consumer Shopping

You have heard of RFID tags, right? The technology that is in most ID cards so admin that or security knows whether staff are in the building or not? Well they are being put into far more than ID cards these days.

They are being put into the clothing of a lot of retail stores and even behind the labels on some tin cans. The situation is certain to mushroom.

They are the new generation of bar codes, but unlike bar codes, they can talk back and they can be so small that you do not even know that you are wearing one. I say ‘wearing one’ because at the moment they are mostly being put into garments, but the day is not far away when they will be under every label of every tin of food that you purchase.

Some stores have even got that far already. Look next time you visit the superstore. Is the check-out clerk scanning a bar code or just scanning ’something’? If there is no bar code to scan, they are looking for the RFID tag.

However, if you had a bar code on your new top, you would remove it before wearing it, but an RFID tag is so tiny and so well concealed, that you may never find it.

Why would that matter, you may be wondering? Well, we are told that it does not matter; that people who do worry are just being unreasonable, but others perceive it as the thin edge of the wedge.

You see, in a city, you are never that far from an RFID scanner, so potentially, if you walk past one, your shirt could be crying out: ‘He bought me from Wal-Mart’. It could also be saying: ‘I only cost 4.99′.

If you do not see that as a problem, all well and good, but what if you are walking down the high street and a loud speaker from a shop shouts at you: ‘People who buy their shirts from Wal-Mart normally love Wimpey Burgers!’.

You may think that that is a twist of fate or you may have forgotten that you purchased that shirt from Wal-Mart, but the tag sewn into your shirt will never forget and it will inform every RFID reader that asks it. Is that fair? You have now become a walking advert.

Of course, RFID tags were not introduced for this reason. They are used ostensibly to help trace merchandise from manufacturer to consumer – point out. They are very useful for tracking stock in a warehouse, but the fact is that these live beacons of their provenance are not turned off at the point of sale. If they were, perhaps there would not be such a problem being raised about them.

Is there a reason to be concerned about these tags? Probably not, but then that does not mean that there never will be. What if you were on holiday somewhere and there was a smart bomb connected to an RFID scanner concealed waiting for an American and your shirt was screaming out: ‘I am a shirt. I was bought for 4.99 at Wal-Mart, store ID 0001, New York, USA’?

Asset Management Techniques

How does one go about taking care of one’s property – one’s worldly possessions? Well, the majority of people put their money in the bank, put the jewellery in a safe and insure the rest. But insurance is not really taking care of your possessions, is it? It is taking care of yourself so that you do not have renew them with your own money.

In the old days, and even now, I suppose in some places, you would hire a boy to watch over your sheep or cattle or bring them in at night for fear of big cats, wolves or thieves. These were an early kind of security guard and indeed wealthy people had and often still do have personal body guards.

What if you had a large office with a hundred laptop computers – laptops because employees had to do field work too? How would you keep track on all those? A car is another good case in point and construction site machinery is being stolen all the time even from under the noses of (or with the help of) private security firms.

So what can you do? Get dogs? That works sometimes, but they can be poisoned. Get video cameras and passive infra-red movement sensors linked to a control centre? That works and many firms and private houses have it, but it is very expensive.

As a low-priced alternative, the police were giving out free pens in the UK, which wrote in invisible ink. The idea was to write your postcode and house number. This ink became visible under a certain kind of light. That is all very well if you have a suspect or found goods.

Bar codes are not realistic, the pen is better. It all comes back to insurance or security.

However, there is another technique that is becoming affordable. The concept has been around for about 85 years, but it was too expensive to use on anything less significant than an airplane or a battle tank.

I am talking about radio frequency identification or RFID for short. The idea is the same one that aircraft have been using since during the Second World War – a transponder emits precoded information in answer to a demand from an RF reader.

Details regarding ownership and details of what the item is can be written to an RFID chip also known as a tag and the tag can then be taped inside the item that it is to safeguard.

There are two varieties of tag: the passive and the active. Passive tags will only respond if information is requested by a reader, whereas an active tag is always broadcasting.

Many business people use RFID tagging to keep track of their assets. In the case of farm animals, most cattle are tagged these days. Most big offices have their IT devices tagged as well and we all know that clothing stores have been tagging clothes for years, although perhaps you did not realize what that button was that they were removing at the till.

People are already tagging their dogs, cats and cars and it will not be long before these asset management routines will be employed extensively at home too. Insurance companies may insist on it.

RFID – Some Basic Facts

RFID stands for ‘Radio Frequency Identification’. It involves the utilization of an object normally made of plastic or metal to identify an object in a similar way to bar codes identify items. In fact, they are used in a very similar way to bar codes and, at least for the foreseeable future, are usually used in conjunction with bar codes.

However, RFID tags are a great deal more adaptable than a piece of paper with a few black stripes on it. RFID tags can be and are being sewn into clothing and fitted under the skins of animals and humans for ease of tracking. Many of the goods you buy in supermarkets these days have RFID tags concealed in them, but do not try looking for them because they can be minuscule. They can also be under the labels of those tins of beans on your shelf.

An RFID tag is used to be able to follow an item from manufacturer to consumer, but especially when it is in the warehouse or supermarket waiting to be sold. A tag reader will be able to transmit the tag’s information back to a computer to warn management that something is near its sell-by-date, for instance.

Tags in cattle allow the abattoir to be able to trace the animal back to a farm and pass this information on to the butcher. An RFID tag under your dog’s skin or your car’s bonnet will allow it to be found if lost or stolen.

There are essentially two types of RFID tags: the passive kind and the active kind and there is a hybrid as well. The passive tag is similar to a bar code. It bears the same information and then more in addition. Similar to a bar code, it can do nothing on its own, but when it is read it will divulge its data. These tag readers give the tag enough power to be able to send the information back to it.

The active tags have a battery and a transmitter constructed into them, so that they can actively broadcast the data all the time and the hybrids will only transmit when ‘turned on’ by a tag reader.

There is still some disagreement about how far away a tag reader can read a tag. In the instance of a passive tag, it centres on the power that the reader can supply over a long distance. Most are designed to work over only a few inches or feet, but more high-capacity ones could be constructed. Active and hybrid tags actively transmit, so they can be read from 100 metres (300 feet) or more.

These tags have been around for a very long time in one form or another, but certainly since the Second World War, when they were used to identify home-coming British planes to save them from the RADAR-directed anti-aircraft guns.

The concern as far as many organizations are concerned, is that technology has progressed so much that the tags can be practically invisible and the readers could be anywhere, which evokes concerns for personal privacy.

A Short History Of RFID Or Smart Tags

As you perhaps already know, RFID is an acronym for ‘Radio Frequency Identification’ – it is the thing that makes ID tags work – but you probably only started hearing about it over the last couple of years. So, how much do you know about RFID? In this piece of writing, I want to take a short look at the history of this seemingly new invention, which has entered almost every facet of a city-dweller’s life and that of many livestock farmers as well.

The start of it all was in 1915, say some, when the British come up with a system called IFF, which is short for ‘Identification: Friend or Foe’. Whoever invented it, the first known installation of the IFF transponder was into the FuG German aircraft in 1940 in the course of the Second World War.

However, IFF does not distinguish enemy aircraft, it can only identify friendly aircraft. All others have to be treated with misgivings. The same type of technology is still in use in military and civilian aircraft today. The British managed to interpret the FuG’s signals and reply properly, giving them a false positive, which gave them the advantage in a dog fight.

At the end of the war and the commencement of the Cold War, Leon Theremin invented a device for the Soviet Union which retransmitted incident radio waves and other audio details. It is not true RFID, but it is accredited with being a predecessor of RFID, because it was a passive device which was activated by an outside source.

In 1948, Harry Stockman wrote a paper called: “Communication by Means of Reflected Power”, in which he stated: “… considerable research and development work has to be done before the remaining basic problems in reflected-power communication are solved, and before the field of useful applications is explored”.

This was true. The problems were basically threefold: the devices needed a lot of power to work effectively; they were too big for use in anything but big items like aircraft and they were very costly. However, people could already envisage uses for the technology when these three problems had been overcome.

(In 2009, researchers at Bristol University stuck RFID devices to live ants to track their behaviour).

The first modern predecessor of the RFID device was something that Mario Cardullo demonstrated to the New York Port Authority in 1971. It was a passive transponder which transmitted information employing power supplied by an external source. It’s proposed use was to identify ships to the Port Authority for the intention of collecting toll fees.

Steven Depp, Alfred Koelle, and Robert Freyman demonstrated a set-up in 1974 which used RFID tags. This has become the basis of the system which is now extensively used all around the world to collect toll charges on autobahns and in car parks.

Charles Walton was granted the first patent to use the acronym RFID in 1983.

The principal user of RFID tags is the US Department of Defense and after that the civil aviation industry, although the manufacturing industry is catching up quickly with RFID tags being used to track goods from manufacture to point-of-sale.

Automatic Identification Systems On Boats

Automatic Identification Systems, or AIS, are electronic transponders that are placed on ships or boats that identify it by name, position, type, & call sign. The signal is VHF that is continuously sent out over the course of the vessel’s travels.

This VHF signal is valuable because it relays information to other ships about its direction of movement as well as well as its speed. The final result provides a visual reference about all enabled vessels that are transmitting within a VHF range. It helps to reduce the chances of collisions on the water by moving water vessels that have the systems. . The data that is received by other AIS-enabled vessels is primarily shown on a personal computer screen or placed as an overlay on a chart plotter. This can help to verify radar readout.

Ship navigators utilize AISAIS as a navigational tool to reduce the risk of collision and to chart a safe course to travel. Maritime search and rescue operations can be made much easier by automated identification devices that will specify the exact location of the distressed vessel regardless time of day or the weather conditions.

Avoiding collisions by programming of specific vessels is information that is exchanged automatically by the systems allowing for safer navigation. Ships with over 300 tons of cargo & all passenger ships are required by the International Maritime Organization to be fitted with the marine guidance system. Recreational boaters are not required by law to use the technology, but the maritime technology is increasing in demand by those users. All over the world, it is thought to be used in over 40,000 vessels.

This maritime technology is used primarily to avoid collisions. It is not a perfect system all in itself. There are known limitations of VHF radio communications, not to mention that not all vessels are fitted with the transponders. It really is just an added tool to that helps determine risk of maritime collision. It is definitely not an automated collision avoidance system as specified by the International Regulations for Preventing Collisions at Sea (COLREGS).

During sea navigation, identifying other ships in the area is crucial for captains to make the best decisions on any voyage. That also does not mean that all additional forms of navigational observation is thrown away. There is certainly, obviously, visual observation in which the captain will often use binoculars to spot far away obstacles or ships. There can also be audio observational alerts that a captain has to listen for such as sirens, whistles, or VHF broadcast. Finally, there is radar or Automatic Radar Plotting Aid (ARPA) that can provide beneficial navigational data to enhance what the AIS is plotting. Despite having all this kind of technology, accidents can still happen. It is frequently due to time delays and limitations of radar or even just plain human error when this takes place. The graphical charts and all the other observational tools must be utilized if water travel is to be safe and AIS is a small part of that.
