reader and transponder

LEGIC products and services encompass all the components necessary for contactless people identification solutions.

Contactless people identification is based on RFID (Radio Frequency Identification) technology. An RFID system consists of a transponder, which is carried by the person to be identified, and a reader that reads the information stored on the transponder.
The contactless coupling between the reader and the transponder occurs via alternating electro-magnetic fields generated by the reader. Not only does this transmit data, but it also supplies the transponder with energy.
The reader is equipped with software that controls the reading process and, if necessary, interfaces to the host system.

Basic components

The LEGIC technology platform consists of the following basic components integrated in readers and transponders:

basic components


Transponder chip (ID medium)
Passive memory chip with up to 4 kB of memory, for integration into cards, key fobs, keys or as a virtual transponder in bank cards, credit cards or mobile phones (NFC).
