Using an Equitrac reader we are seeing that the UID extracted from a card (decimal) does not match any of the numbers imprinted on the card. My customer has MIFARE cards which are pre-printed with numbers they use with their door entry system - first four digits of the number printed on the card equals a users "PIN". When we read the card into the equitrac system we receive a 20 digit length decimal value with no correspondence to the number printed on the card. Is this typical?
