1. I am working on an Android project which relies on the unique UID of a discovered NFC tag to process the tag. I extract this UID using the following code: byte[] extraID = intent.getByteArrayExtra(NfcAdapter.EXTRA_ID); However, for some technologies this UID is randomly generated for security purposes.What I want is to write an app that will be triggered by NFC tag. When the app starts, I want it to display a toast message containing the UID of the scanned tag. My simple code to achieve this is: @Override. Reading Tag UID. You can read the tag ID of the tag using the following method. fun getUID (intent: Intent): String { val myTag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG) return BaseEncoding.base16().encode(myTag.id) } Read Tag Data. You can read all the NDEF . When an Android-powered device scans an NFC tag containing NDEF formatted data, it parses the message and tries to figure out the data's MIME type or identifying URI. To do this, the system reads the first NdefRecord inside the NdefMessage to determine how to interpret the entire NDEF message (an NDEF message can have multiple NDEF records).
To read the UID of your NFC tag with an Android smartphone open the free app NXP TagInfo. Now hold the NFC tag to the upper back of the smartphone. The smartphone usually vibrates after the tag has been completely scanned.
