APDU has been sent first.

00 20 00 00 Len Data to be verified
CLA is always 00
INS is always 20
P1 is 00

Lc is the number of bytes for verification:
If the value is 00, the status 63Cx will be returned where x indicates the number
of further retries allowed. This mode does not use up an attempt!
If the value is the one less than the value of Property A7, the PSC contained in the
Data Field will be presented for verification.

Possible SW1/SW2 combinations:
SW1/SW2 Meaning
