Jakcom R3 or R3f "smart" ring

edited July 17 in RFID/NFC
Anyone has some genuine Intel about this ring? Because the information out there is very confusing. What exactly types are the ntags in them? What's the memory? Are they UID writable? Do they accept 13.56MHz and 125khz? Where do you buy a genuine one? (considering their site is caca). How do they work with standard antena or with the Proxmark?

Any info would be appreciated mates

  • Honestly, I can't see much use for this thing other than the NFC which is likely a 1k capacity with around 888bytes usable. If that's the case, I'd rather get one from a reputable manufacturer with plenty of information and support i.e. https://dangerousthings.com/product-category/limited-time-nfc-rings/

    That's the thing, can't find the correct specs or where to buy a genuine one to play with. Some adds show it has a 13.56MHz (dunno which ntag exactly, hence no memory detail) and also an 125kHz chip... I mean that would be a cool toy for a beginner like me to play with...
