RFID (Radio Frequency Identification) is a technology for detection and location of objects via radio communication.
In the past this technology was used by military for detection and recognizing of own and enemy troops.
Now it will be used not only by army. Modern retail security systems in the super marks and other shops are based on the RFID technology.
The criticism of RFID grows parallel with the increasing of RFID expansion on the civil market.
The data protection specialists warn that consumer in future will not be able to control the data transfer of RFID.
There is a danger that RFID will be transformed in some kind of tracking cookie in real world.
I think that it is impossible to stop this transformation, because of great interest of the big companies on it. But I think that in future we will able to buy special devices that will be able to detect and destroy RFID chips.
