Standard Card Format
Standard format cards are used with all Site Controllers. They are used to initiate a fuel
transaction from the ICR or to access fuel from the postpay-prepay console. Standard cards
can have all the information encoded onto one card (single card) or can have the information
split between two cards that must be used together (dual cards). Systems can have a
combination of both single and dual cards; they are not restricted to only one type.
Single cards are commonly used when a vehicle is assigned to a single driver, or in a retail
application when only an account number needs to be identified. A card encoded as a single
card cannot be used as a dual card. Dual cards are useful when employees operate different
vehicles, but you still want both the employee and vehicle numbers to be identified. If a
system is set up to accept dual cards, both cards must be used; neither card will be accepted
independently unless you are using them at a gate controller where either one of the cards will
be accepted.
The next two subsections describe the card field layout for both single and dual cards.
Single Card Layout
The card layout for a single card is -ssssss-ccccccccccccccccccc-yymmllaapprr, where:
• “-” is a field separator. In case of a dual card, the first two characters would be field
separators.
Note: Field separators are used on Mag Cards only.
• “ssssss” is a two- to six-digit system ID number.
• “-” is a field separator.
• “ccccccccccccccccccc” contains up to 19 digits of account information. This entire area
can be used for a string of information up to 19 digits, or can be split into sub-fields
(maximum of three fields on Site Controller I), the total of which cannot exceed 19 digits.
For example, if you use 19 digits for a card number, you cannot define any other fields.
Usually this 19-digit area is split as follows:
- The first field is a four- to six-digit card number.
- Fields after the first field are broken down into vehicle, employee, account number,
department, or whatever you specified when you ordered for the system.
• “yymmllaapprr” implies any optional information.
• “-” is a field separator.
• “yymm” is a four-digit expiration date with yy being the two-digit year and mm being the
two-digit month. This field could also use only two digits (yy).
• “ll” is a 0, or a one or two-digit limitation code.
• “aa” is a 0, or a one or two-digit authorization code.
• “pp” is a 0, or a one or two-digit price level.
• “rr” is a 0, or a one or two-digit restriction code. Depending on its value, the dollar
amount, odometer, vehicle number, PIN, or a combination of these must be entered by the
cardholder.
