Where can I find a lock with an nfc chip?

Question

NFC

Maybe there are people here who understand electronic locks and share their experience of what to watch out for and which one is better to put.
I would like to find under these criteria: an overhead electronic lock only with nfc and automatic code generation in the application on the phone + a mechanical key if the energy in the batteries runs out. No fingerprints or anything.
