Longer Answer (Since Amal sniped me)
Well, Quite a few of the HF implants use ISO14443A
The ApexFlex doesn’t mention it on the store, but if you scan it with TagInfo, you see
There may well be more to it than the protocol, but to confirm, the bracelet he used was a Mifare Classic 1k

So
Yes you are correct, xMagic, FlexM1, FlexMT
I read it ( reddit ) and the dude just used the dreaded White Cloner.
Basically the easiest way is to copy the card onto an xMagic
Yeah, you really should, its a great implant
of course
You could also TRY and use the Apex, and IF it is compatiable, it MAY read a little easier, BUT you’ll need to figure out HOW to enroll a new “Card”
