What is RFID?
RFID, Radio Frequency Identification, is the technology that lets you simply wave your credit or identification card, passport or license in front of a nearby scanner instead of having to slide the magnetic stripe through it. You may have already seen these scanners at local stores labeled as "pay pass" "express pay" etc...
How does it work exactally?
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. Unfortunately, criminals with minimal technical skills and electonics bought off the internet can construct their own "remote scanner" or build an Iphone or Android app that uses their cellphone or tablet.
These devices can steal your private financial information quickly and silently. All a crimiinal needs to do is get close to you, wallet or purse using their hidden card reader! Some technology allows criminals to use long range scanners so they do not need to be near you.
