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.

I've had this ring for a few months, and it is very handy to have 2 high-frequency 13.56 MHz Mifare Classic 1K, 2 NTAG 216, and 1 (or 2) low-frequency 125 kHz writeable cards on a single ring.Many hotel keycards and some office buildings use Mifare Classic 1K HF cards. The F0 can clone these with the NFC Magic app to the Magic Gen1a chips straightaway. Because of the smaller action distance of HF cards, these are very easy to copy to one side without interfering with with the chip on the opposite side. If I'm traveling for work, I have an office ID on one side and my hotel keycard on the other. Very convenient.The NTAG 216 chips found 90 deg from the MFC1K chips are perfect to write digital business cards to. Want to pass contact info to someone? Rotate the ring 90 deg and tap the back of a smartphone for a quick transfer. Copying to them can be done as above with an F0 or NFC Magic, or with a smartphone and NFC Tools to create a VCard.The 125 kHz LF (T5577 chip) cards can be tricky. Before writing to them with a F0, you need to clear the password (125 kHz RFID > Extra Actions > Clear T5577 Password). However the F0 will disable both passwords using its included dictionary (5469616E for one side, 51243648 for the other) since both antennas are so close together, meaning that the next Write and Set Password will set one side and leave the other side open. I could probably target each chip individually with my Proxmark3 Easy, however I haven't had the need yet. LF HID is fairly old and really insecure, so only one office building I access really needs it, and I've only needed to program one.I was also initially very concerned about the "health stones" set in the ring. Some of these, often marketed as negative ion stones, are actually producers of ionizing radiation. If this were the case I would have returned the ring immediately. However tested with a Geiger counter, no beta/gamma radiation over background was detected. Phew! Really if they're magnets or crystals or whatever woo, at least they're not dangerous and the ring is useful so it stays.

This would be nicer if the ring wasn't hilariously big, and if it supported the common t5577 tag type. Unfornuately neither is the case. It is cool that it has both NFC and IC tag types, and it actually seems to work decently depending on the direction in my testing. But alas it was useless due to the insufficient support of RFID tag types.

Normal 125khz reader writer will not work for these. They have a password according to customer service that I don’t know how to enter but I can read and write my apartment key fob to any other card or key fob so it’s useless to me.

Ring is smart.Still learning tags.

I read all discrimination about this product but there is something wrong it’s not as good as shopper give information about this product battery life is so poor only 48 hours battery life of this product every other day I have to charge it so please don’t give wrong information about product

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.

Large,bulky.someone who runs business using credit cards etc would have greater use gor
