This disclosure is directed to devices, systems, and techniques for establishing a secure connection between two or more devices. In some examples, a device is configured for wireless communication. The device comprises signal reception circuitry configured to receive communications transmitted according to at least a first communication protocol, communication circuitry configured for wireless communication according to at least a second communication protocol, and processing circuitry electrically coupled to the signal reception circuitry and the communication circuitry. The processing circuitry is configured to receive, via the signal reception circuitry, a first signal according to the first communication protocol. In response to receiving the first signal, the processing circuitry is further configured to transmit, via the communication circuitry, a second signal according to the second communication protocol and establish a secure link according to the second communication protocol.

Establishing a secure communication link

A method and system for communicating data between controller and a transponder where the processor is powered by current received from an antenna. The controller is magnetically coupled to the transponder to sense impedance variations in the transponder. The impedance of the transponder is altered by varying current used by a processor within the transponder. The processor current is controlled by varying the processor clock rate.
