CEPAS EZ-Link newer cards and Pixel #174

Closed mranostay closed 5 years ago

mranostay commented 5 years ago

Newer EZ-Link cards don't seem to work at all on a Google Pixel. And NfcTool can't detect it all even, but can confirm it is readable with an ACR122U reader + laptop.

Can dump the last 30 transactions using pn53x-tamashell + raw commands.

Newer card that doesn't work (Expiry date: 29 Jan 2025)

Guess my main question is newer CEPAS cards using some new spec that isn't compatible with older readers (aka the NXP chip in the Pixel) or somewhere in the Android NFC stack it isn't validating that a supported card is in range?

More debug.. so Pixel is detecting the NFC card

Testing with a new EZ-Link card and it works as expected. So likely it is a combo of the coil in the NFC card, and the antenna of the pixel is why the other one can't be read.
