Aprox card is a card is a card unless you do more things with it. And that’s what is happening as radio frequency identification (RFID) in its many increasingly powerful forms becomes a diverse security and business tool to apply to people, vehicles, assets and even processes. Active or passive, more or less intelligent, contact or contactless, with ranges from inches to feet, RFID is suddenly the super solution.
Most enterprise security leaders know RFID as the proximity card, contactless integrated circuit (IC) devices for security access or payment systems. Proximitycards are powered by resonant energy transfer. They are, at their basic, an automatic data collection solution. RFID systems consist of an RF tag – or a transponder: a radio receiver or transmitter that responds to an external signal by automatically transmitting a signal – and an RF reader/controller.
