CNICK Smart NFC RFID Ring: Door Access, Manage NFC Android Devices and APPs, First Wooden Smart Ring for Men and Women

It's clearly says RFID. Well I just got mine and it's not. It just doesn't work. Not even the NFC. Maybe mine is defective. But I'm just sharing my experience. I was really excited to switch both my RFID access cards to this one ring but no such luck. So I decided to write at least my business card info into it Vía NFC. No luck there either. The ring isn't bad looking but it's just not THAT appealing to wear just because.Oh BTW in the official video it says it's waterproof but in the brochure tells you "take it off when showering"

Unless you have a powerful NFC reader, this is basically useless. Doesn't work with a phone unless flush against the NFC antenna, doesn't work with any NFC device that runs off of batteries. It looks better than most NFC rings, and that's about all it's good for.

Finish has already come off after wearing less then 10 days.

I always had to carry three access cards: one for gym, another for office and for my apartment. Have tried few cheap NFC rings but non of them worked, barely was able to make it readable by the reader. Also build quality they had was very crappy. Recently friend of mine gifted me CNICK and wow I am really astonished with the performance, just have to touch finger on the reader, don't need to find specific spot on the ring and what a quality, handcrafted with tons of attention to details and really feels special with wood texture.
