Мобильная версияВот некоторые подробности о моей реализации:
- Регистрация AID: я зарегистрировал правильный AID для значка Vigik в файле прав и правильный тег тип опрашивается с использованием NFCTagReaderSession.
- Обнаружены другие карты: карты NFC, такие как ISO 14443 и MIFARE, обнаруживаются и считываются правильно.
