The reader ACCEZ-30-AUT is a cheap proximity reader that works standalone and can be fixed directly to the lock of the door or electromagnet.
 
The reader can store up to 30 different card/key codes and it’s very practical because it works without the need of any controller or software.

It works at a frequency of 125 KHz with “accez-card” or turnkey tags model “accez-tag”. The reader has an input for connecting an exit push-button that activates the relay. The activation relay is temporized and can also be configured as bistable. The reader is supplied with 1 card and 1 tag free, considered as “masters” that allow memorizing more cards when they have been previously approached to the reader.
