Magic Ring - Magic Mifare 1k + T5577


Should be a quick question.
The magic ring has 2 dots on one end and then 1 dot on the other end. Which one is the Mifare chip and which is T5577 chip?

single dot

Double Dot
Mifare Classic 1k gen2

It’s mentioned in the video, pretty early on (within ~10secs)

I’m surprised its not on the webpage !

Was there any documentation with the ring?
