RFID Question.

[kd8bxp]

From the documentation https://docs.m5stack.com/en/core/M5Dial The Dial uses the WS1850S rfid chip, the same as the RFID2 Unit https://docs.m5stack.com/en/unit/rfid2 I have no problem reading NFC512 ISO14443A Sticker tags with the RFID2 Unit, but the Dial will sometimes say UNSUPPORTED, or mostly it just refuses to read them at all. IF it's using the same WS1850S chip, should it also read the same tags? I used the demo code for the RFID2 Unit and the M5StickC-Plus without issue. And the demo RFID example here in this repository for the Dial. Both will read the credit card type MIFARE cards with out any problems.

I am very confused by this behavior thou, any suggestions - or maybe a different sketch/library to try. Thanks.
