ID Module Chip: T5577 x2 Carrier Frequency of ID Module: 125KHZ ID Module Feature: Equivalent to two EM ID cards with card number repeatedly modifiable. NFC Module Chip: Ntag216 x2 Carrier Frequency of NFC Module: 13.56MHZ NFC module features: Equivalent to two NFC smart cards which can interact with smart phones NFC Phones applicable: All Android phones with NFC function, as well as for iPhone launched after September 2018, such as for iPhone XR, XS, 11, 12 and 13 Ring Material: Ceramics Ring Weight: 9 Grams Protection Grade: IP56 Tips: Ceramics has good scratch-resistance, but it cannot bear violent collision or drop. Please be careful in use the ring have two ID module, They are prone to signal conflicts, so the ID password we set ID1 = 5469616E ID2 = 51243648 If your device supports the setting of encryption ID card editing, enter the above password to edit. The IC modules of R5 ring are two 13.56MHz frequency rewritable Mifare1 type IC cards, and the chip is CUID; The ID modules of R5 ring are two 125KHz frequency rewritable EM/HID type ID cards, and the chip is T5577; The NFC modules of R5 ring are two 13.56 MHz frequency Ntag type2 NFC cards, and the chip is Ntag216; The R5 ring can be 2 IC cards 2 ID cards and 2 NFC cards at the same time. Writing new card will overwrite the old card; The reading and writing process is the same as ordinary cards. If you still can't solve it, We recommend that you take the ring to your original card issuer, and let them add the ring as a new card to their system. Structure and Sensing Range A. The area engraved with "I" is No.1 IC card B. The area engraved with "II" is No.1 NFC card C. The area engraved with "III" is No.2 IC card D. The area engraved with "IIII" is No.2 NFC card E. The white side area is No.1 ID card F. The black side area is No.2 ID card G. Health energy stone 1 H. Health energy stone 2 Reading method of IC and ID module： The reading method of any IC or ID module is the same as an ordinary card, Close to the card reader according to the sensing range shown in the figure above. Sketch Map Use No. 1 IC card, Use No. 2 IC card Use No. 1 ID card, Use No. 2 ID card Tip: the antenna of each module shall be parallel to the card reader to be sensed, The closer the distance, the more sensitive the reader will be. Setting method of IC and ID module： Any IC or ID module can be regarded as a new blank card, and the setting method is the same as an ordinary card; At the original card issuer, add the IC or ID module as a new authorized card; Review: Waste of money, unable to write to ring. - 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. Review: Works well with a Flipper Zero, now I have 5 (sometimes 6) card clones in one ring - 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. ## Features - CatXQ Smart Ring:Built-in NFC module Easily Share Digital Business Card, Social Media (Facebook,Instagram,Twitter,Youtube,TikTok),can realize virtual call,Scene notification,Memo sharing and other featured cloud services. - CatXQ Smart Ring:Built-in IC and ID modules,6 smart cards can be simulated at the same time (Access Card,Elevator Card,Time card,Parking Card,Membership Card,Shopping Card and Other RFID Cards),the read-write process of ic/id card module is the same as ordinary cards.within the sensing range of the ic/id module,it can be authorized or copied by the corresponding dedicated read-write devicel. - CatXQ Smart Ring: Built-in 128G Wireless USB Flash Disk,Use ring touch to transfer any files, and each ring has exclusive 128GB storage space. - The Smart Ring can be set as a trigger for the intelligent scene of MI Home Smart Devices. - We provide 24-hour after-sales service.

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. ## Frequently Bought Together - CatXQ Smart Ring for iOS Android | 2 Health Stones,6 RFID Cards,128G Wireless USB Flash Disk,Digital Business Card,Share Social Media | Ceramic Ring for Men Women - L - Oura Ring 4 - Silver - Size 8 - Smart Ring - Size First with Oura Ring 4 Sizing Kit - Sleep Tracking Wearable - Heart Rate - Fitness Tracker - Up to 8 Days of Battery Life - Oura Ring Gen3 Heritage - Silver - Size 9 - Smart Ring - Size First with Oura Ring Gen3 Sizing Kit - Sleep Tracking Wearable - Heart Rate - Fitness Tracker - 5-7 Days Battery Life --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.es/products/506893127-smart-ring-for-ios-android-2-health-stones-6-rfid](https://www.desertcart.es/products/506893127-smart-ring-for-ios-android-2-health-stones-6-rfid) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-06-09*
