p . The

S821 is able to read Texas Instruments (ISO 15693) and

Philips MIFARE smart cards.

For either type of card, the S821 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 the

"smartMAX TI" format.

The reader can simultaneously support two different card

types/formats (e.g. "smartMAX TI" and MIFARE). The

reader is automatically configured to accept the first two

card types/formats presented.
