Expiration Date Field Card Field Descriptions
To facilitate card administration, card numbers should be assigned sequentially.
When using dual cards, Account Information fields are usually encoded on one card or the
other. In Mag Card systems, field separators take the place of the card number on the other
card.
Expiration Date Field
The Expiration Date field is used on the following cards: Standard, Manual Entry, Fuel
Delivery, Supervisor, Dipstick, Fueler ID, Totalizer, and Access.
If used, this field can be of two or four digits. It is assigned to establish a lifetime for the card.
The default is four digits, where the first two digits represent the year and the last two digits
represent the month. If the field is two digits, both represent the year and the cards are valid to
the end of the specified year.
When using dual cards, the expiration date may be encoded on one or both cards. If the
expiration date is encoded on only one of the cards, field separators replace it on the other
card. If the expiration date is encoded on both cards, it must be the same.
The cards may all be coded with a date in the distant future (up to 50 years) or you may use
this feature to issue a temporary card (pending a credit check or other approval measure).
Using an expiration date two or three years in the future can help keep your negative file of
locked out cards from reaching an unmanageable size.
Note: The CFN system can be configured to ignore the expiration date described in page 4
and 5 of SYS_PAR.
Limitation Code Field
The Limitation Code field is used on the following cards: Standard, Supervisor, and Access.
If used, this field contains a one or two-digit Limitation Code (also called Limit Cutoff) that
determines the maximum amount of product that can be dispensed in a single transaction.
Most applications use one digit. Limitation Codes are provided mainly as a safeguard to
minimize accidental spillage. When customers reach their limit cutoff, the transaction
terminates immediately. If the customers want additional product, they can reactivate the
dispenser and dispense the product again up to the limit cutoff.
When you use dual cards, the Limitation Code is usually encoded only on one card, typically a
vehicle card. In Mag Card systems, a field separator takes the place of the digit on the other
card.
