Appendix B. PINpad 101 Device
Introduction
The PINpad 101 data entry device accepts spersonal identification numbers (PINs) for Debit card transactions. The PINpad 101 device uses a master key and a working key to encrypt the PIN input. Typically, a PIN is a 4- to 12-digit code known only by the customer and the bank. A PIN is used during retail transactions to verify that the customer is authorized to use the credit card offered; the PIN also serves as the cardholder identification for the credit or debit transaction.
The PINpad unit connects to a TRANZ 460 terminal that controls PIN entry operations and does the actual communication with the host computer.
