Question about this door lock
Wondering if a ring will work with this door lock or if you guys had any feedback. It says M1 card but I'm assuming that means there's at least some NFC functionality?
It may not necessarily work, because even if it uses the same ISO standard and frequency it really depends on how the door reads the storage.
Here is a reference to an old post from 3 years ago for a similar situation you're facing: https://forum.nfcring.com/topic/76/samsung-shs-2920-does-not-work/16
In short, the door may read the M1 card but not NTAG203 that is used in the ring.
