RF Identification

Radio Frequency Identification (RFID) involves contactless reading and writing of data into an RFID tag's nonvolatile memory through an RF signal. Adding an external antenna to a chip is all that is needed for a complete an RFID tag. The reader emits an RF signal and data is exchanged when the tag comes in proximity to the reader signal. The RFID tag derives its power from the RF reader signal and does not require a battery or external power source.

Atmel offers a complete line of contactless RFID products (ICs, micromodules and complete transponders) operating at 125 kHz, 134.2 kHz and 13.56 MHz. Adding an external antenna is all that is needed for a complete RFID tag. Atmel also offers reader chips for a complete RFID system. Applications include security and access control, manufacturing and logistics, brand protection, and animal indentification.
