What is RFID technology?

RFID tags are similar to bar codes, but they use radio waves to transmit information short distances. Most of us periodically use RFID technology by going through payless electronic toll centers on highways or utilising the “Fastpass” admission system used at many amusement parks.

How to use it when you travel?

RFIDblocking wallets are designed to help insulate you from a very particular brand of electronic pickpocketing, called RFID skimming. When activated by an RFID reader, these chips transmit certain types of information wirelessly, so that you can verify your identity or even make a purchase without swiping your card.
