DESFire EV1 Transponder (locking
media)
You use DESFire EV-1 locking media in two different modes:
DESFire EV-1 in security mode (optional)
Locking devices and locking media operating in the security
mode (1) are manufactured exclusively by CEStronics and
programmed with individual keys and special firmware.
The data transmission between the locking device and the
locking medium is encrypted. Only locking media that are
authenticated by the device are authorized to lock or unlock.
This ensures a very high protection against manipulation.
These locking devices (1) will not accept any foreign
transponders (2); they do not respond to any locking or
unlocking attempt with other locking media.
A DESFire EV-1 locking medium manufactured by CEStronics
operating in the security mode can be used in other systems
(3) requiring this type of transponder.
This ensures the multi-application capability of the locking
medium.
