JAKCOM R5 SMART RING New Wearable Device Build-in 6 RFID Cards & 2 Health Stones

I own an R4 and love it, but the etchings are sometimes hard to read when orienting the ring. The R5 solves this problem by properly visually indexing the chip locations with hash marks on a white background. The ring does require a separate programming tool to read from original cards and and write to the ring. The NFC chips are managed through some excellent software hosted by Jakcom and allowing the ring to provide a wide variety of functions beyond the transmission of a Vcard. My only disappointment is that it arrived with a tiny chip in the surface of the ring. These are ceramic and extremely delicate with regard to sharp impacts. It is not affecting the function of the internals, but is a minor sensory distraction when the finger rubs it wrong. Educate yourself before buying, it's kinda techie. Overall really cool technology!

I bought this to replace my security fob at work. In order to do that I had to:1 - Have my IT & Security staff verify that the protocol was compatible with our system.2 - Confirm that they would allow me to use this.3 - Have Security/IT add it to the system for access (this is in addition to copying the signal from the fob to the ring).Ultimately for our specific security system, this ring can replace my security fob on all of the hard-wired doors but, so far, it won't work on the wi-fi fob readers.I will add an update if I they can get it to work on the wi-fi readers, or if I try any other features.Lastly, I went with the "Large" and it is similar in size to a US ring size 12.

Okay I love this ting and the many different functions it has. I use it for iOS automations in shortcuts integrating the NFC chips on the ring. One side I use for some of my interior smart locks. I wish I could have used the ID part of the ring but the badge I wanted to copy to it uses a T5577 chip and that format is not compatible with this ring unfortunately. That really is my only gripe with this. It's definitely water resistant, I've washed my hands with this multiple times and it still works just fine. This is definitely a game changer!

The ring is awesome, it came in the wrong size the company was awesome and gave it to me free to try.and share with others. Works great.

The description is misleading, there is not 128GB of storage in this ring, you can only trigger actions trough NFC You have 2 IC chips rewritable, and 2 NFC chips, but you can't write on the 2 chips ID/HID card.

Ring seems to work as intended but damn is it THICC definitely designed for some big hands.
