Hi Tithi,

If your card is in state SL1 (MIFARE Classic compliant) you can prepare the switch to SL3. SL1 is ISO/IEC14443-3 and SL3 ISO/IEC14443-4. This is the reason why you cannot do the switch in one session; the protocol is different for both security levels.

For switching, you must store the “SL2 switch key” (an AES key with 16 bytes) in 0x9003. Here you must go through the “Activate Ide” and “RATS+PPS” protocol steps. If you remove the card from the reader and start a new session, the card should be in SL3.
