Support for TCOS MyCard?

Hi All,
I’m able to partially read this type of NFC card with my mobile phone but with Flipper it does not detect it at all.

NFC Tools Pro detects it as an ISO 14443-4 by Fujitsu with IsoDep and NfcA technologies.

Hm, the Flipper should be able to at least read the NFC-A data of the card

We’ll look into that

Can the Flipper emulate these type of cards? It reads right away, but when emulating it won’t trip the door I’m testing on. Any ideas?

I did try to get the flipper to read one of those cards and did not succeed at first. My phone (Pixel 6 Pro) was also not able to read it. When I tried a Samsung phone, it was able to read the NFC-A parts just like you, so I tried keeping the card with one half under the phone to keep it powered, and then tried reading it with the Flipper and it did read out “Unknown ISO tag, ISO 14443-4 (NFC-A)” and the UID
