D ESCRIPTION :
MAC is an acronym for Message Authentication Code. The MAC
WORKING KEY is used to verify messages to and from the termi-
nal. The MAC WORKING KEY is a 16-character string, consisting
of the digits 0-9 and the letters A-F. Your processor must provide
you with the MAC WORKING KEY. If a MAC authentication at-
tempt on a message fails, the message will fail. This is a security
precaution.
For security reasons, when entering this key, a ‘*’ is displayed in
place of the actual character. Since it is not possible to view the
key while it is entered, the key must entered in twice to make sure
it was entered properly.
To enter a digit 0-9, simply press the key that has that digit, and a
‘*’ will appear. To enter the letters A-F, first press the <CTRL> key,
then press the key that has the letter you want on it. The first press
of the key will display the first character above the number. Sub-
sequent presses will display the characters in sequence. When
the character you want is displayed, press the <RIGHT ARROW>
key to ‘lock in’ the letter. If your next character is a letter, you must
press the <CTRL> key again. Press the <CHANGE> key to clear
the entry and start over. Press the <LEFT ARROW> key to back
up and erase a character.
Normally, the MAC WORKING KEY contains only one part. How-
ever, some keys may contain multiple parts. If this is the case,
separate individuals will hold the parts. If your key has multiple
parts you must answer the question “ANOTHER KEY PART?”, with
a YES until all parts are entered.
In some versions of ATM software the
MAC WORKING KEY entry screen
accepts the digits 0-9 and the Hexa-
decimal (“Hex”) characters A-F. On
such screens, to enter a digit 0-9, sim-
ply press the key that has the desired
digit. To enter a Hex character, first
press and hold down the <CTRL> key.
While holding down the <CTRL> key,
press the numbered key (1-6) that cor-
responds to the character you want
to enter, as listed in the table on-
screen (1=A, 2=B, 3=C, 4=D, 5=E,
6=F). Release the <CTRL> key. Re-
peat for each character in the key.
Press the <CHANGE> key to clear the
entry and start over. Press the <LEFT
ARROW> key to back up and erase
a character.
If your key has multiple parts you must
answer the question “ANOTHER KEY
PART?”, with a YES and enter the
next key part until all parts are entered.
