CARD LAYOUT AND FIELD DESCRIPTIONS
Card Layout
This section describes the card layout and field descriptions for all mag and 
optical card applications. It also lists special considerations for cards compatible 
with GASBOY CFN systems, GASBOY "A" System optical cards, and 
Commercial Fueling Network systems. Considerations for GASBOY CFN 
systems will be identified as GASBOY CFN; Commercial Fueling Networks will be 
identified as CFN Network, GASBOY "A" System will be identified as "A" System. 
If no special considerations are noted, the field works the same for all systems. 
Since card layout is customized for each order, all of the described fields need not 
be present. The descriptions list which fields are optional and which fields can be 
customized. 
Single Versus 
Dual Cards 
A Series 1000 System can have its encoded information on one or two cards. 
When a single card is used, all of the information is encoded on one card. This is 
typically used when a vehicle is assigned to only one 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. 
When dual cards are used, the encoded information is separated onto two cards. 
For example, employee information is encoded on one card and vehicle 
information is encoded on another. Some data is encoded on both cards. This 
makes it possible for employees to operate different vehicles, and yet have both 
numbers identified. An employee card must be used with a vehicle card; neither 
card will be accepted independently. 
Most cards used with the Commercial Fueling Network are single cards.
What’s on a 
Card? 
The Series 1000 cards are encoded with information to control access to the fuel 
dispensing equipment, the type of fuel(s), and the maximum amount of fuel 
dispensed per transaction. The system also provides for variable identification 
fields (ID Field 1 and ID Field 2) to allow users to customize the system to their 
particular information requirements. The names and sizes of the identification 
fields must be specified at the time of order. The user may also specify which 
card the various information fields are encoded on in a dual card application. 
The following pages describe the standard Series 1000 information fields 
encoded on the cards. Fields noted Mag Card Only pertain only to mag card 
systems and are not available with optical card systems. Card layouts for both 
mag and optical card systems and CFN Network cards are shown in Figures 2-2 
through 2-3. 
Card Type (Mag Card Only)
Standard
Card type is always the first field encoded on the card. It is a 1- or 2-digit field 
and is encoded with field separators. One field separator indicates a single card; 
the system will not prompt for an additional card for system access. Two field 
separators indicate a dual card (e.g., employee card); the system will prompt for a 
second dual card (e.g., vehicle card) before allowing access. 
CFN Network
Cards for the Commercial Fueling Network are generally single cards.
