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.
The PINpad device components include:
•
8-character display
•
12-key telephone-style keypad
The 8-character display shows up to 16 characters through automatic
scrolling. The PINpad 101 device displays fully-formed numerals, letters and
special characters * and #. Information displayed includes characters entered
from the keypad, instructions, prompts and error messages.
