Flex NFC Repeaters 13.56mhz Range Extenders by Midwest Gadgets LLC on Tindie

I have one on my android.
they are really awesome.

iPhone antenna placement is more awkward, but for $10, worth a try…

let me dig out a thread that I can think of that might explain it more

More than one on xMagic

Hey, I got an Xmagic chip in my left hand, which I use to open doors. It works as a clone from a Mifare Chip from Salto.I did that with a proxmark3 and the clone tutorial. Can I write additional info on that 13.56Mhz Chip like text or data? Thanks for your help
