ARC-B MF DESFire reader+interf. +keypad

The ARC-A and ARC-B readers use the latest MIFARE® and DESFIRE® contactless chip technologies with new data security mechanisms. They implement public encryption algorithms (TDES, AES, RSA, SHA, etc.), as recommended and recognized by the French national security agency ANSSI. The reader design has been developed to withstand harsh environments and has a reinforced structure to resist to physical attacks. Thanks to the capacitive technology, the keypad of the ARC-B is sealed and protected from the accumulation of dirt. It also prevents the premature mechanical wear of keys, common on conventional keypads available on the market. The decoder / interface is a data encryption and authentication device for read-only readers. This smart decoder converts Secure RS485 communication into a plain Wiegand, Data / Clock or RS485 communication. This decoder assures confidentiality and integrity of the communication between the reader and the system.
