E Ticket Rfid Smart Card

Smart cards often called Proximity or RFID cards are becoming more popular among business and hotels and other controlled secure facilities. These smart cards can have a single electronic component to multiple components packaged into a very thin plastic card. The card emits a low power signal around the device and a receiver that is specifically tuned to locate the card is matched to a computer controlled data base that can verify the presence of the card. These cards are found at airport Clear Card check points, Passports, and even quick pay terminals at some fuel stations.
