Radio-Frequency Identification (RFID) is the use of radio waves to read and capture information stored on a tag attached to an object. A tag can be read from up to several feet away and does not need to be within direct line-of-sight of the reader to be tracked. How RFID works? RFID chips work by using radio waves to communicate. The object, such as a credit card, contains an RFID tag with information, and an RFID reader uses radio waves to read the information from a tag. The key is that RFID chips have tiny electromagnetic fields, which is what makes them possible to read without having to “initiate” communications. Why use RFID Wallet? RFID-blocking wallets are designed to help insulate you from a very particular brand of electronic pickpocketing, called RFID skimming. The concern is that some credit cards, passports, and driver’s licenses now come with embedded radio frequency identification chips. 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. This wallet includes Embedded RFID-blocking shield which prevents electronic identity theft.
