Waterproof Ceramic NFC Ring, NFC Forum Type 2 215 496 Bytes Chip Universal for Mobile Phone, All-Round Sensing Technology Wearable Smart Ring, Fasion Ring for Men or Women (8#, Black)

03/08/2026 Update: Ordered a #9 to get a size 10. Attached a video of how well it works when loading a web link to a digital business card. The iPhone sensor is at the top of the phone while android (garbage) is in the middle of the phone. When you have the right size, and know what you’re doing (not hard) the ring performs well. I think a lot of reviewers simply don’t know what they are doing and then write a bad review. Old Review: If you are looking to program this ring using NFC Tools on the iPhone to put a simple website link for your electronic business card, then this ring works great!! The ring works really well on iPhones and androids once programmed this way. If you are trying to use the ring for something else, I have no idea how good it is. I did return mine and why there is 4 stars, is that they have a discrepancy in their Amazon listing so that the ring sizes are not correct to what you click on. For instantance, the #10 is actually a size 11. I need to reorder but the event I wanted it for passed. I will eventually reorder a size 10 because it does work well and looks cool when someone can tap your ring and have your info. I was not compensated for this review but if the seller would like to, please feel free!

Nice look but the NFC feature are not compatible with iPhone 13pro max.

works like it should

Like: It works. It is readable and writable. Other RFID rings in this frequency did not work or only worked if you took the ring off and held it sideways to the reader. This ring actually works, but may take a few tries. It is NOT as easy to read as a card key, but I always have this on so it's a good backup if my thumb is wet or dirty, or if the fingerprint scanner is wet.

I was planning doing various things with this ring. But it's lost so maybe I'll try again it took so long to receive it though.

It does the thing well

It looks cool and is pretty comfortable, but it is already programmed and it isn't able to be changed. I used i used an rfid/nfc reader and writer and I wasnt able to program anything on it and when i scanned it it showed up with the numbers 0014550152 which means it was already programmed

I purchased this NFC ring for the chip to use as an ID badge at work. I was very delighted when I found out that an iPhone could write to the ring using NFC Tools. I was able to upload my contact information to the ring and then password protect it so no one else could write to the ring but me. Yes it does come with it's own set of ID numbers programmed into the chip. That is the point of having it. It is a unique address for the chip to create an original ID for the device, and those numbers cannot be changed. You can however, add more data to the ring, such as contact info., addresses, websites, text messages, and emails. P.S. only 4 stars because the smallest size is 7 and largest size is 12. This needs a wider range of sizes to be perfect.
