RFID embedded cards use radio frequencies to transmit data. These cards have been in use in Europe for many years but are just coming into use in the world. The idea is that consumers should be able to use these cards at stores and restaurants to pay for purchases without having to swipe the card through a scanner. Many people remain concerned, however, that the RFID technology may also allow thieves to use scanners to intercept the radio waves and steal the card's information. While technology has made significant security improvements in the past few years, some concerns still exist.
