Suica works but other Japanese rail cards do not (they are identified as suica)

[CountParadox]

I have tested with a number of Japanese rail passes that use felica and are interoperable.
Suica seems to work but all other cards I have tried including pasmo, ICOCA, kitica, sapoca will identify as suica but not display any balance or data.

Hi @CountParadox , do you mind confirming which firmware you were running the app with? I just tried momentum and OFW on my end, and momentum fails reading Pasmo or Suica, while OFW can read both. This is a known issue with momentum. But if it's not related to firmware we can proceed to next step.

Ah, I am indeed on momentum! Do you have a link to the issue on their end ? I would love to read how this happens

Actually we found this maybe last month and mentioned to Willy in private, not in a public post. I'm not sure if anyone ended up finding a reason why it happens. I tried some debugging myself and couldn't spot any obvious reason. However, have you tried OFW and does that solve the issue? I'm curious whether it's the firmware issue in your case.

This should be fixed once flipperdevices/flipperzero-firmware#4254 is merged. Momentum seems to have a different way of handling poller event that I can't yet figure out how. Regardless, the reading we need will be done by the firmware's poller_run instead of our homemade handler suica_callback. Once that PR is merged, Suica's workflow will be offloaded. I will PR a Metroflip fix once I get affirmative reviews on OFW, which should be subsequently downstreamed to Momentum.
