Hello,

Currently I use typical ID cards to unlock doors in my institution using NFC. I am trying to manipulate the Pass.json file to allow for NFC Door Unlocking.

Here is what I think I will be using:

{"nfc":{"message":"EXAMPLE","encryptionPublicKey":"EXAMPLE"}}

What I am trying to do is extract the NFC data from my ID card and use it for the NFC message in my Pass.json.

If there is any help on how to extract this it would be greatly appreciated.

Thanks

Apple Wallet passes use a proprietary protocol called Value Added Service which is only implemented by specific readers, usually in Point-of-Sale terminals, and very rarely in access control. Additionally, in order to use the nfc key in the pass.json file, you have to receive a special Pass Type ID certificate from Apple.
