What is RFID?
RFID, or radio frequency identification, is the technology that lets you simply wave your credit card, passport or license in front of a nearby scanner instead of having to slide the magnetic stripe through it. The electronic scanner sends a signal which is received by an antenna embedded into the card, which is connected to the card’s RFID chip, thus activating it. The RFID chip in these cards emits all of the information, including the account number, which is needed to complete a transaction.
