HID I10304 Format

Hi Everyone,

Does anyone know what HID "I10304" format looks like?  It's a 37 bit format.  I have the bit structure for H10304, which is different.

Thanks in advance,

Re: HID I10304 Format

This is what I know about 37-Bit I10304 format


The format consists of 2 parity bits, 6 bit Facility Code and 16 bit Cardholder ID fields. (dont know what the other 13 bits are

P?????????????FFFFFFCCCCCCCCCCCCCCCCP
EXXXXXXXXXXXXXXXXXX..................
..................XXXXXXXXXXXXXXXXXXO

P = Parity
O = Odd Parity
E = Even Parity
X = Parity mask
F = Facility Code, range = 0 to  65,535
C = Cardholder ID, range = 0 to 524,287

Re: HID I10304 Format

I got my hands on a 37-Bit I10304 format card

Written on card
18724 11101973657-3

Trace of the card
https://pastebin.com/mre0hdP3

I believe the Facility Code is 61 and card number is 18724 but when i run a search this is what is returned.
