The “key” to choosing the right proximity access cards for your existing access control system is to match the credentials to the formatting of that system. A standard 26-bit card won’t work with a 37-bit system—instead, browse our selection of 37-bit H10304 Wiegand proximity access cards and fobs.

Our credentials compatible with 37-bit card formats include durable and convenient key fobs, as well as both printable and clamshell cards. (Please note: our clamshell cards will not work with inkjet printers!) Choose an access control solution that will integrate seamlessly with the format you’ve already got in place, like a 37-bit H10304 Wiegand 125kHz proximity card.

Got any questions about the inner workings of our 37-bit H10304 Wiegand proximity access cards and fobs? Need help programming your access fobs or cards? Please reach out to us at support@authoriz-id.com for further assistance.
