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.

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.

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.
