How does it all work? Card is inserted in the terminal Card gets power. OS boots up. Sends ATR (Answer to reset) ATR negotiations take place to set up data transfer speeds, capability negotiations etc. Terminal sends first command to select MF Card responds with an error (because MF selection is only on password presentation) Terminal prompts the user to provide password Terminal sends password for verification Card verifies P2. Stores a status “P2 Verified”. Responds “OK” Terminal sends command to select MF again Terminal sends command to read EF1 Card supplies personal data and responds “OK” Card responds “OK”
