# Card format matching tool

Don't waste time figuring out a bit format by hand.

This tool allows you to paste in a set of bits or hexadecimal value and we'll scan through all of our known card formats and try to find a match, then decode it. It is one of many resources we provide for free, including our [bit format comparison](/content/tools/bit-format-matcher#/index.html) and our [nfc access control guides](/content/guides/index.html).

If you'd like your format added to this page, just [email us](mailto:ab@accessgrid.com).
