TLDR:Despite the advertising, this ring does not allow you to clone multiple HID cards onto it, it is nothing but a headache and waste of time. Details below.DETAILS:This ring contains 6 different chips, the two I'm interested in writing to are the ID cards which are "EM/HID" according to the manufacturer.The problem is that since the two chips, ID1 and ID2 are so close in proximity, they can't be written to by normal RFID tools such as the Proxmark3 or Flipperzero as they would both be written to at once and interfere with each other.Their solution was to password protected the two chips with different passwords which they provide so you could write to the desired chip by "specifying the corresponding password" when writing. The problem is the Proxmark3 and FlipperZero can't write to this ring specifying a password.Jackcom suggests using their Jakcom CDS Replicator for the R5 ring in order to clone to to this ring since their replicator is designed to target each chip separately, the replicator comes with two physically different readers / writers. One is designed to clone to chip ID1 and the other to ID2.The problem is reader 1 can clone HID cards just fine, but reader 2 does not detect HID card at all.After speaking with support, I was told the second reader can't read HID cards because the ring only supports cloning one HID card.This is NOT what Jackcom advertised for the R5 ring or the replicator. This has wasted hours and days of my life. This ring is a joke, it does not work as advertised, and I STRONGLY recommend staying away from it if your goal is to clone multiple HID cards onto it. You are better off buying two separate 125KHz rings instead.

Ring is smart.Still learning tags.

This ring does not have any storage on it. You can configure one of the NFCs to pull up a link to a 128GB cloud storage. Wireless USB is total BS, it's just cloud storage - and I got that confirmation from their support.The ring is incredibly thick, probably twice the thickness of a regular ring, though I was actually surprised that it was comfortable for the 30 seconds I had it on given how thick it was.
