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.
