System ID
Standard System ID is a four-digit field which denies users of other systems access to your
customer’s system. When using two cards, the system ID is both encoded and
verified on each card.
GASBOY CFN For GASBOY CFN, the Series 1000 may have a five- or six-digit system ID field if
it is being configured to match a CFN system with a five- or six-digit system ID.
CFN Network Commercial Fueling Networks have a fixed system ID, supplied in the program,
which cannot be changed. In addition, a dual system ID option is available which
provides a second system ID to be entered via the system ID prompt in the
system configuration. This unique system ID is supplied on the card layout.
"A" System When matching "A" System cards, the Series 1000 system ID may be from 1 to 6
digits.
Start Field Separator (Mag Card Only)
One field separator is encoded after the System ID to indicate the beginning of
identification data.
Card Number
Standard Card Number is a four-digit field (allows up to 9,999 users) which is used to lock
out cards from system access. When using dual cards, the card number is
usually encoded on only one card. In dual mag card systems, field separators
take the place of the card number on the other card. In dual optical card systems,
all of the holes are punched in the card number position on the other card. If the
card number is encoded on both cards, it must be the same on both cards.
Assign card numbers sequentially from 0001 to facilitate card administration.
Option Effects If you have the fuel delivery and dipstick option, cards encoded with the range
9980 to 9989 initiate a fuel delivery transaction; cards encoded with the range
9990 to 9999 initiate a dipstick reading transaction. If you have the supervisor
card option on an optical system, any card within the range 9930 to 9979 is
treated as a supervisor card.
CFN Network With Commercial Fueling Networks, card number is a 7-digit field which is used to
lock out cards from access to the system. Most cards used by the CFN Network
have six of the seven digits for the card number encoded in the card field and an
additional digit, CARD MSD, (most significant digit) encoded at the end of the
card string. This digit, if used, becomes the first digit of the CARD field. If this
digit is omitted, the first digit on the CARD field is assumed to be 0, otherwise, it is
the value of the digit (for example, if the last digit is 7 and the card number field
contains 123456, the actual card number would be 7123456). Although encoded
this way, when card numbers appear in transactions, the entire 7-digit number is
shown.
