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

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

Therefore, the technology needs to be sensitive and discriminating, but not fragile, because the equipment 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 have to have a tag, which is an smart 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 data 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 information. Obviously, active RFID tags are more costly than passive tags, because they require a long life battery.

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

This has ramifications for the amount of stock that a company has to hold, the quantity 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 connected to the checkout cash registers, which are the most and least profitable articles. This makes reordering simple . Easy to the point of automation. For example, when supplies of the top ten percent of the best selling products falls below 1,000 order 10,000 more. Automatically, no questions asked.

RFID has many other uses as well. The ideas outlined above can be applied to farm animals, a call centre’s computers, a fleet of commercial vehicles, an inventory of domestic items, your pets, your car and even your garden furniture. Some individuals who work over a boundary are even having them placed under their skin so that they do not have to wait at customs.

And bear in mind that criminals on early discharge are also tagged. It is the same technology.

In order to illustrate how RFID tags can really influence the fortunes of a company for the better, we shall take a look at a theoretical case below. Let us take the example of a furniture maker that specializes in the supply furniture to a hotel group.

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

The principal requirements of the hotel chain are that orders are complete and on time, the quality of the supplier’s goods 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 producer had employed a few people to walk around with bar code readers and clip boards carrying out quality control and tracking the fulfillment of orders.

The problem was that the system was still subject to human error and items still went missing, which lead to 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 articles of furniture that are implicated in a hotel room, bathroom or lobby and if they are stored in a 200,000 square foot warehouse. Things get lost, forklift drivers make errors, people forget to fill in stock forms, get sick and take vacations.

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

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 opportunity to manage, cut down on waste, guarantee complete orders handed over on time and so superior levels of customer satisfaction, which should lead to more repeat orders.

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 kinds of RFID tags: passive, active and hybrid. Passive RFID tags are the least expensive, because they are less complex. They have to be asked to disclose their information by taking power from an RFID reader. When the reader’s radio waves hit them, they echo back their information. 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 antenna so that they are always sending. These units are clearly 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 costly, but the battery lasts longer because they are not ‘always on’. These tags have the same applications 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 placing 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 replaced as and when necessary. If this is going to unlikely to happen, as in the case of wild animals, the tag can have a biodegradable clasp which will break sometime after the probable life of the battery.

Some uses for RFID tags are on season tickets so that the holder can pass through the style more quickly than a customer paying by cash. It has uses in security; most of the ID badges you see pinned to jackets have RFID built into them so that security guards do not have to stop and question 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 use them on patients so that they do not lose anyone or mis-identify them. RFID tags are useful in our daily lives but people are worried about criminals being able to read all this information too easily 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 presume in some places, you would employ a boy to watch over your sheep or cattle or bring them in at night for fear of big cats, wolves or rustlers. These were an early kind of security guard and indeed wealthy people had and often still do have private 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 plant is being stolen all the time even from under the watchful gaze 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 cheap 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 special kind of light. That is fine if you have a suspect or found property.

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

However, there is another way that is becoming reasonably priced. The idea has been around for approximately 85 years, but it was too pricey to use on anything smaller 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 entrepreneurs use RFID tagging to keep track of their assets. In the instance of livestock, 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 garments for years, although maybe you did not know what that button was that they were taking off at the checkout.

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