Contactless Digital Security

The difference between contactless smart cards & RFID tags

Overview: what happens in RF (radio frequency) communication
?When a contactless smart card or an RFID tag passes within range, a reader sends out radio frequency electromagnetic waves.	ŤThe antenna, tuned to receive these waves, wakes up the chip in the smart card or tag.	?A wireless communications channel is set up between the reader and the smart card or tag.
