GPShell first does a GET DATA to retrieve the Card Recognition data. Part of the returned blob is an OID (defined in Appendix H) which describes the supposed SCP for the card - in this case, the data is "2A864886FC6B040215" - or an OID of 1.2.840.114283.4.2.21. The last two number define the SCP (2) and the options (21 dec - 15 hex).

The GlobalPlatform libraries - if told to use mode 211 - check this to figure out which SCP. The lib doesn't appear to check the returned value from the INITIALIZE UPDATE to make sure it really is SCP 02.

The card recognition data is obviously wrong - but the question is what's the right behavior here? Throw an error on the mismatch, or pay attention to the SCP value returned by INITUP and do the right thing?

The asn1 dump of the card recognition data is

$ ./dumpasn1 resp.bin

   2 7: OBJECT IDENTIFIER gpRecognitionData (1 2 840 114283 1)
