What is this card you mailed me?
-
This card came in my last order. Does this card do anything? Is it RFID?

@frank26080115 I think we all get them...M5Stack just trying to create interest in RFID sensors!

@frank26080115 Its one of a series of collectable custom designed RFID cads M5Stack give away free with each order.
They are usable with the RFID unit or the RFID face. -

Do these work at 13.56? How are they formatted? I cannot get my iPhone 11 to read them.

@wsanders
They won't work with phones as phones use the NFC version of RFID which works on a different band.
