MagicRing has no markings and maybe no LF?

Just got a chance to unpack my MagicRing, and noticed it seems to lack both the one- and two-dot markings that are supposed to indicate which side is which. Has the design changed from what’s on the sale page?

Additionally, while I can read the Mifare side okay with my PM3, I can’t get much of a fluctuation on lf tune out of the T5577 side. With the ring off and placed on/held directly above the antenna cover, I can’t get any fluctuation regardless of orientation. If I place the ring on my finger, fiddle with the rotation a bit, and cup the PM3, with the ring physically touching the cover over the antenna, I can get a 2-3V drop or so. Can’t search/read/write even that way.

No problems with the sample cards that came with the PM3 — 17V+ drops when tuning, and quick and accurate reads/writes on all the LF ones (and with a handful of others I had lying around the house). Haven’t done much testing with the HF ones that came with it yet, but the one or two I’ve tried have been readable just fine.

Fairly new to fiddling with RFIDs. Is there something I may be doing wrong set-up wise, or is it possible I just got a bad one?

Did you get a version one or version two? Version 2 of the Magic Ring does not have any dots because there are no sides on v2.

Photos of the ring and you placing it on your proxmark3 for LF programming would be helpful!

It is the V2 - thanks for the clarification!

Here are some shots of the ring above the scanner with tune in the background.


Almost forgot — while taking these I realized the only reason I was getting a fluctuation the other way is because I was accidentally touching the screws holding the antenna to the board — I get the same dip with the ring nowhere nearby.

Unfortunately,
I don’t have one of these to test for you, and
I also don’t know if these come pre-programmed in EM mode like the implants do, but you could try an lf search and/or lf t5 detect command if you havent already.
Even though the tune doesn’t seem like its detecting anything, for a few seconds of “work”, it may be worth a try :man_shrugging:

Unfortunately I’ve tried the search — it doesn’t find any data:

The t5 detect command also just comes back with a message that it cannot detect modulation automatically. Appreciate the suggestions though!

Hmm. I would try just programming it…

lf em 410x clone --id 0102030405

Hmm… tried programming it with the id for a keycard for a lock in my office. It said “Done”, but I couldn’t read it after with lf search or lf em 410x reader, and it didn’t work with the lock.

Gotta step away from the PC for a bit, but should be back to try any other suggestions later this evening. Thanks for all your help so far!

At this point it seems like you might have gotten a faulty ring! If you can’t get it working then reply to your order confirmation email and reference this forum thread and we’ll get you sorted out

For tests sake try lf t55 detect on the opposite side to the HF chip where the low freq chip should be.

Lf search would only find the t5577 if it’s already been encoded as an LF chip, which I don’t know if the magic rings are by default.

Keep trying the detect command in a few different orientations, passing over the antenna with the ring not in the middle blank space

It’s a v2 so there isn’t a “side” … this is correct for a v2;

Word^
Do this orientation with the lf t55 detect command

Do this orientation with the lf t55 detect command

Will do — thanks, everyone, for your help diagnosing!

Quick update: the new ring got here today, and the read/write for both Mifare and T5577 are working perfectly. Absolutely loving it — thanks for the fantastic help and support!
