In the images/video on the Magic Ring page, there’s a 1-dot marking (location of LF) and a 2-dot marking (location of HF). My ring just arrived yesterday, and it only has the 1-dot marking.
I’m just checking that this is intended/known, and that it won’t affect the performance at all (e.g. if the holes improve the antenna reception through the ring). Does anyone know?
The good news is
Most Likely, The one dot is still the T5577 chip, and on the opposite side SHOULD be the MF1k chip, that you can easily test with a phone.
Scan it with your phone, and if it reads, you should be golden.
Do you have an iPhone, Android, or something else?
What other RFID tools do you have? A proxmark? A flipper zero?
I have a Flipper, and was able to write to both the T5577 (with the Flipper) and the MF1k (with MCT on my Android phone). They both read back just fine on the Flipper/MCT as well (I compared the files to the reads).
It’s probably fine. I’m mostly checking as I don’t know if the missing dots could indicate a manufacturing defect, which might only cause problems after a few weeks/months from now.
It’s a defect turned into a feature. We got a whole batch without the two dot marking and effectively it makes the markings more subtle which I think everybody appreciates? We were often asked if we could make the markings less visible and I think this achieves that goal by accident?
