Notes:

  1. The Card Format is interpreted from the bit pattern to be one of the following: Standard 26 Bit, Generic 34 Bit (Even or Odd Parity), HID Corporate 1000 (35 Bit), HID 37 Bit (with or without Facility Code), Casi-Rusco 40 Bit.
  2. The Internal Card Number is usually the same as the External Card Number (the number printed on the card itself), however it can be offset.
  3. "Facility Code" is "Company ID Code" in the case of 35 bit (HID Corporate 1000) cards.
