Timeskey NFC Tags Ntag215 NFC Keytags Black NFC fob Rewritable NFC 215 Tag NFC Business Card Programmable NFC Tag Commercial Access Cards 504 Bytes Memory，Compatible with Android & iPhone（50pcs）

I wanted to learn and play with NFC tags. This seemed like a cheap way to start. Programmed a tag with an Android app, made it read only and read it with my Android phone. Worked perfectly. A friend's I Phone wouldn't read it, but I was expecting it not to be simple with an Apple phone.Seems to be rugged. I've had it on a chain with a lot of keys and it hasn't broken.

I bought these for use with my Veise Smart Lock RZ06; they were very simple to program and all of them work

We recently got a new TownSteel smart lock, but didn't like the flimsy RFID cards that came with it, so lucky I found this. I like that it matches my other key fob and that it comes in multiple colors. The plastic looks a bit thin but it's been holding up so far. The only issue I have is the actual keychain part is super flimsy, so I immediately took that off and attached it to my existing keychain instead. For me, I didn't need this many NFC keys, but as an Android user, I know i can find clever uses for the rest of these.

Tags work well, but are not actually rewritable. That’s my only complaint.

Son muy prácticos y cómodos de para cargar en las llaves y no se olvida de marcar a tiempo.

It works great, but be sure to pause for a few seconds in order for it to work.

These tags are easy to read from and write to, and they are convenient to carry on a keychain or on a strap for a purse, backpack, or briefcase.

Just got these delivered and within minutes I was able to program a couple extra 'keys' for my Vsett 9+R. The original Vsett NFC card fell off my key ring and I didn't catch it until the next time I was looking to ride. While I had spares, I didn't want to run into this problem again.Rather than getting more cheaply made OEM cards, I decided to try these. Glad I did, these are much sturdier than the originals and I can't see this one falling off my key ring very easily.Now, I just need to find a use for the other 7 NFC tags.
