Configuring Card FormatsTable 4-13: Card Format Types, continuedFieldIssue CodeFixed DataEven Parity,Odd ParityLRCExpiration DateStatusDescriptionNOTE: If you are configuring an extended card format, and you are includingIssue Code in the card format, use the Card Number field (see above)instead of the Issue Code field to configure the Issue Code. Use IssueCode only for non-extended cards.This field indicates how many times a card with this card number has been issued.When the card is replaced (original is lost or damaged), this value is incrementedby one. The number on the card must match the issue code in the person’spersonnel record.Field within the encoded information that remains the same for all cards used withthe particular card format. Similar to facility and site codes.Select these field types to specify the location of the even and odd parity bits onthe card. Parity bits are included on Wiegand and proximity access cards.When you select a parity field:• In the Start position field, specify the location of the parity bit• In the Parity start field, specify the first bit to be parity-checkedIn the Parity length field, specify the number of bits to be parity-checkedLongitudinal Redundancy Check. This field is only available for extended cardWiegand and Proximity formats.Field providing a way for a card reader to check whether or not a card is still validthrough an expiration date encoded in the card. Once this card format is applied toa given reader, a cardholder whose card has an unexpired data is allowed accessat the door. If, on the other hand, the cardholder presents a card with an expireddate to a reader, the door stays locked, denying the cardholder access.If the expiration date encoded on the card is the present date, the panel expiresthe card at the beginning of the following day.The Expiration Date can only be one format: 64 bits (8 bytes), with one digit perbyte, in the format YYYYMMDD.NOTE: If the expiration date/time configured in the cardholder’s personnel recordprecedes the encoded expiration date, the panel expires the card at theearlier of the two dates.Field where you can specify the start position of the Extended Reader StatusMessage on the card format. The length of the message is fixed to eight bits.4–34 C•CURE 800/8000 Hardware Configuration Guide
