A personal identification number (PIN; sometimes redundantly a PIN code or PIN number) is a numeric (sometimes alpha-numeric) passcode used in the process of authenticating a user accessing a system.

The customer enters a challenge received from the bank's website, a PIN and the transaction amount into the reader. The reader returns an 8-digit signature.
Typically if the PIN is being transmitted over a network (ie not verified locally by the ATM or EFTPOS terminal) the PIN entry device will encrypt the PIN then send the encrypted PIN block to the card issuer and/or bank, which will decrypt and verify it. It is not possible to truncate the PIN while it is encrypted, so it must either be ...
