3.2 - Transponder card and key
Transponder keys and transponder cards offer absolute
safety and reliability. Each key/each card contains a different
code chosen from among more than 1000 billion possible
combinations. The code's uniqueness is ensured by the key
and card production process. They work without a battery,
so they have unlimited, maintenance-free operation.
Operation
The inductive coupling between the connector, which con-
tains the primary winding of a transformer, and the tran-
sponder key or card, which contains the secondary wind-
ing (coil in a small capsule), generates energy that activates
the secondary winding, which responds by modulating and
transmitting the code. The code is transmitted by setting the
transponder key or card into contact (as shown by the posi-
