How send NfcA command to the MIFARE card?

由 限于喜欢 提交于 2019-12-08 04:26:13
问题 I'm writing an Android application. I'm trying to send NfcA low-level commands (in my case: HALT and WAKE-UP) to my Mifare Plus S card. The NfcA tech is for "low-level" access to ISO 14443 Type A tags (i.e. the proprietary protocol as mentioned in ISO 14443-3). This is part of my code: protected void onNewIntent(Intent intent) { if (NfcAdapter.ACTION_TAG_DISCOVERED.equals(intent.getAction())) { tagFromIntent = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG); UID = Utils.byteArrayToHexString
