Function principle
The BLident read-write heads (transceivers) are used for non-
contact data exchange with the corresponding data carriers (TAGs).
They form the so-called air-interface (transfer window), whose size
varies depending on the combination of data carrier and transceiver.
In this air-interface the data carrier is supplied with energy and the
exchange of data is also implemented. The operating frequency is
13.56 MHz.

The achievable distances vary depending on the sizes from 15…200
mm. The read-write heads consist of electronics and an antenna.
