RFID Guardian- Protecting your privacy
Now this is quite ingenious. There are some (not me) who believe that RFID represents a grave threat to mankind. These devices are used to simplify the tracking of goods when being transported and on shop shelves.
Unlike a bar code which has to be scanned, an RFID responds to a signal and returns some useful information from a short distance away. No need to look for the code. But some people are concerned that rfid chips are easily hidden and can be used to spy on you. As the site says “Implantable RFID tags for animals allow concerned owners to label their pets and livestock. Verichip Corp. has also created a slightly adapted implantable RFID chip, the size of a grain of rice, for use in humans.”
So this device detects hidden rfid tags and lets you stops them functioning as long as you want by shielding them from being interrogated.
