Symmetry™ S853
Common Access Card (CAC) Reader
The Symmetry S853 is designed to read the Common Access Card which combines both a
microprocessor contact “chip” (complying with ISO 7816) and Philips MIFARE® DESFire
Contactless Smart Card format.
Designed to meet the increasing demands for high speed, triple-Data Encryption Standard
(DES) Secured Contactless Smart card solutions, MIFARE DESFire is an ideal fit for
service providers and system integrators looking to develop convenient, multi-functional
smart card-based systems for use in identity and e-government as well as other uses
such as transportation, city loyalty and e-purse schemes. The chip’s core characteristics
- Fast, Innovative, Reliable and Secure, as described by the ‘Fire’ part of its
name are supported by a unique combination of flexible memory organization structure
alongside impressive data transaction rates, making it ideal for Secure Contactless
Smart Card services.
MIFARE DESFire operates at a distance of 0.5-1.2” (10-30mm) and in accordance with
the international standard ISO 14443 perfectly meets mid-end segment needs including
security and cost effectiveness. It features a non-volatile memory, a high speed
triple - DES data encryption co-processor, a flexible memory organization structure,
a mutual 3-pass authentication technique together with a true random number generator
and an anti-tear mechanism to guarantee data integrity during contactless transactions.
Unlike Wiegand interface readers, the Symmetry S853 uses secure, bi-directional,
Pseudo-Random
supervised communications between the Symmetry multiNODE controllers and their associated
readers. Both the reader and cable are supervised, and an alarm will sound if the
reader is tampered with or communications lost.
A distance from any of the Symmetry multiNODE controllers to the Symmetry S853 reader of up to 3000ft
(1000m) can also be achieved.
The Symmetry S853 includes an LCD for verification of card accepted and of card rejected.
This LCD is also used for card PIN number prompt and for verification of command
functions initiated through the reader keypad. There is also an integrated buzzer
for confirmation of card read and local door pre-held warning alarms. This integrated
buzzer is also used to give audible feedback for positive confirmation of key press
for card PIN number entry.
