What is a Card Format?

A card format details how a key's data, such as its ID number or facility code, is structured within the card. Physical credentials must be added under the correct format, otherwise your access control system will be unable to properly decode the data in order to recognize the key.

All Sequr mobile credentials have a 37-bit card format. For physical credentials, such as keycards and key fobs, Sequr recommends the use of 37-bit No Facility Code keys, or industry standard 26-bit keys, however Sequr can support most keycard formats. With the proper card data details, Sequr can enable most formats for your system. When your system is installed and your Sequr portal built, the Sequr team will enable any key formats you've requested. 

If you acquire keys with a format different than the one that your system typically uses, you will need to request that Sequr enable the new format for your system. Please reach out to support@sequr.io for assistance.

If you have keycards that are not working on your access control system and you suspect that an incorrect card format might be the culprit, there is a way to check the card format. You can do so by following the steps below.

Finding or Checking A Card Format

1) Scan the key in question at one of your property readers.

2) Log into your Sequr admin dashboard and navigate to your 'Activity Log.' Locate the 'Deny Access - Card/PIN Not Found' event corresponding with the credential scan.

3) Click on the event 'Actions' link and select 'More Info.'

4) A box will appear that lists the card format data. You should be able to determine whether you've added a card under a correct card format by checking the logged Bits, Facility Code, and Card Number.

If the logged data is not recognizable, and you're unsure if your system has been enabled to utilize the given card format, please contact support@sequr.io for assistance.
