MIFARE SAM AV2

The maximum specified bit rate in any case is 1.5 Mbit/s.

8.1.3 Card operation procedures

All card operation procedures (activation, cold reset, warm reset and deactivation) are

fully compliant with Ref. 19, Chapter 5.

8.2 Transmission procedure and communication

8.2.1 Protocol activation sequence

All subsequently described operations are compliant with ISO/IEC 7816-3.

8.2.1.1

Answer To Reset (ATR)

The MIFARE SAM AV2 offers two modes of operation identified by different ATRs.

A negotiable mode where the bit rate has to be adjusted via a PPS request and a specific

mode where the MIFARE SAM AV2 switches automatically to F = 128 and D = 32 (highest

possible speed) after sending the ATR. Starting with the negotiable mode, the mode of

operation is switched after every warm reset.

After a cold reset, the card sends the following ATR to the terminal.

After this ATR, the card is in the negotiable mode and waits for a PPS request. If a warm

reset is issued, the MIFARE SAM AV2 switches the mode of operation, enters the specific

mode and sends the following ATR.
