| Radio Frequency Identification (RFID)is surprisingly prevalent in our everyday lives. While earlier, similar technologies like IFF Transponders, which indicates whether aircraft were friend or foe, were developed for wartime use. RFID has a plethora of civilian uses. Most of the wireless devices we use and take for granted utilize RFID Tags to work.
Cash and credit cards use RFID tags within the cards in order to store the information needed for them to work. Some libraries use RFID Tags replacing barcodes and storing information about the book. Also, some countries use RFID tags in their passports to store data about the person.
A rarer form of RFID use is the implantation of RFID tags into humans in order to quickly identify a person. This form of identification is not very reliable however as it is susceptible to real life intervention such as forcing the man’s hand (Containing the RFID tag) on the reader.
