RC522 based modules for Arduino etcetera. Not Recommended.
This RC522 based module, while it does work with the NFC Rings has a very poorly matched design and has difficulty triggering a read except in one very specific spot for each ring.
Not recommended for use with the NFC Ring.
Available on ebay in various colours, usually rebadged by the seller.
I'm having problems getting the RC522 to detect my NFC ring. Any tips on chip settings or tuning to make it work?
In all honesty, my number one tip would be "choose something else". It does not work well with the NFC Ring, as per title and post content.

Does it apply to
20162015 models, or only for original ones?
As my original post says, the matching is very poor. I don't recommend the RC522 with small form factor NFC tags, it's not what that unit is good at doing.
