S841 Contactless Smart Card Reader

S841 Contactless Smart Card ReaderThe S841 is a contactless smart-card reader, with LCD and keypad.

The S841 is able to read Texas Instruments™ (ISO 15693) smart cards, and the card serial number on Philips® MIFARE® smart cards.

For either type of card, the S841 supports the use of unencoded cards (where only the unique card serial number is read). In the case of Texas Instruments (TI) cards, an encoded card number can be read. Encoding formats supported include TI's own formats and G4Tec’s own "smartMAX" format.

The multifunctional memory structure of Smart Cards makes them ideal for use in data security-sensitive multi-application systems such as access control, cashless vending, etc.

The S841 is designed for use with G4Tec’s multiNODE-1000, multiNODE-2 SMD, multiNODE-2000 and multiNODE-2100 controllers and is compatible with G4Tec's Symmetry Business, Symmetry Professional, Symmetry Enterprise and Symmetry Global Software at Version 4.0 or later.

Unlike Wiegand interface readers, the S841 uses secure, bidirectional, Pseudo-Random supervised communications between the 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 the multiNODE controller to the S841 of up to 3000ft (1000m) can also be achieved.

The S841includes an LCD for verification of card accepted and of card rejected. The LCD display is also used for PIN prompt and to give verification of command functions initiated through the reader keypad.
