YARONGTECH 13.56mhz RFID 1K Evolis Printable White PVC Card for Door Entry Access Control (Pack of 10)

This was recommended in Reddit for Aqara u100. I tried other NFC card and they didn't work. I use to have Level lock with card and loved that format. I bought the original Aqara NFC but they are not convenient and lost some easily. Non branded so nobody will suspect aqara. Shipping was on the slower side compared to other items on Amazon but these were definitely worth the wait and did deliver faster than advertised.

Used for aqara u100

These are much cheaper and more convenient than key fobs, and they work just as well. They fit nicely into a wallet or purse pocket. If a guest losses one, not a big deal, we can just revoke the key and they're super cheap to replace. They are a bit glossy and fingerprints show up easily, so need to be cleaned between guests. Overall, if your lock works with a 13.56 mhz RFID fob, these are a great alternative.

It’s a piece of plastic. Nothing to write to inside. Not being even detected. Worthless.

Work perfectly on Aqara locks, in case you were wondering.

I got these for backup purposes if everything else fails (thumbprint, key code, Siri, etc) and had zero issues adding it to the User Management options. I normally use my Apple Watch Ultra to unlock it, but the U100 is not compatible with Android's NFC, which my wife uses. She's already locked out the device by doing too many attempts too fast (of course) so I ended up getting another YARONGTECH product, their key fobs. https://www.amazon.com/dp/B01FR6VGYA Those were just as easy to set up, and they provide quicker access (if she's having issues using her thumb) since it's easier to pull out your keys.

Worked as promised.
