You have probably already had problems identifying yourself or something in a machine. Exercise your mind trying to remember that day you needed get money at a cash machine and your bank card was rejected, or when you went to a hospital and you had to write all your personal information in a form, or else every day when you need to buy products in a supermarket and the cashier spends fifteen minutes just to register all of the product in the system.
If you expanded this exercise as a manager in a supermarket, could you imagine how many products you would need to control in your stock? Or as a doctor in a hospital, could you figure out what medicine each of your patients was taking just looking at their faces? Or else as a cash machine, how could you know if the client was getting money through a stolen bank card?
So, we may conclude we have these same problems. Each one of these scenarios creates problems related to time, information security, data reliability and other issues.
Trying to solve these problems, the world of technology presents the RFID. This technology is based on radio frequency waves, which have been used for more than a hundred years as a telecommunication solution, and now comes to identify people, products and places through tiny components of less than fifty millimeters.
As soon as you notice, you have already used RFID tags to make your routine easier. If you work in a large building where there are hundreds of people transiting per day, you must have a personal card to identify yourself electronically at the lobby. With this card they are able to find your personal identification with your address, picture, the company’s name that you work for and your last visits.
Another application of RFID technology is that it may speed many regular attitudes such as buying products. Imagine you get into a supermarket or a drugstore, select products and go out without long lines, or even waiting for the change. The whole bill would be debited from your bank account or your credit card. It would be possible if every product had a RFID tag keeping the unique identification and price, then each product would do self registration at the cashier and then you would just needed to permit the debit through self-service terminals.
Unfortunately this isn’t the present reality because the technology still expensive and there are some problems related to technology aspects such as battery life time and some privacy concerns such as access to personal information without prior permission.
The main concern about privacy is the possibility that everyone might consult personal information about anyone, or even worse, steal the personal identification. It was proven by researchers that duplicating identifications was possible through catching the RFID waves propagated by tags and then decoding these waves and recording them onto other tags. Another concern is, everyone would be able to consult any product that someone is using in that moment being able to know the product price, where it was bought and worse, the unique identification product that may provide means to steal customer information.
This technology continuous being researched and maybe there will be solutions for all these problems soon. Some figures show an increase of RFID use by 2010 and meanwhile many investments has been made by universities and research centers.
Stay aware about it!
