@gornekich are you ok with this kinds of type check? As i understand we can make it through data->type == MfUltralightTypeMfulC?

[bettse]

I did see MfUltralightTypeMfulC, mf_ultralight_get_type_by_version, and instance->data->type, but seems I'd need an MfUltralightPoller, and I'm still not very good at the NFC api and opaque types and casting stuff and whatnot, so I wasn't sure how to get from the nfc_device I saw to there.

Hello @bettse . The best way to check ultralight type here is to cast nfc_device data to MfUltralight pointer and check it's type. Please look at patch attached.

Thanks! That works (tested with amiibo and hotel card) and is much more semantic
