A 4 byte ATR is returned when the power up command is successful. Many I
2
C  cards do not
deliver an ATR on power up, but some do. If the value FFFFFFFFH is returned, the card did not
deliver an ATR. The presence or absence of an ATR may not

specifications for the various cards to determine which ATR identifies which card. If
FFFFFFFFH is returned, the card may be an I
2
C  card that does not deliver an ATR. The only
way to be sure is to send a Read Binary to retrieve known data from a card you are familiar with.
