Hi there,
Sorry to disturb you.

I'm comfused to a problem in the ISO7816-3, as regard to T=0 protocol.
It said, a card can response a "60" as NULL procedure byte to extend waiting
time.
And when the should have valid data to send back, such as response to "GET
RESPONSE" command,
how the interface distinguished the NULL PB form narmal data in the
response, which is followed by SW1,SW2.

Any comment is appreciated.
Thanks.

B.R.
Wayne
