Hello,

Sorry for my very bad english...

Is it possible to get the physical adress (serial number) of the tag with NFC library ?

If yes, how do this please.

Thanks in advance.

Many thanks Erel,

But i don't understand why scanning the same tag 3 times, the "android.nfc.extra.ID" is never the same ?
It is not the tag ID ?

Bundle[{android.nfc.extra.NDEF_MESSAGES=[Landroid.os.Parcelable;@424bb968, android.nfc.extra.ID=[B@424bcef8, android.nfc.extra.TAG=TAG: Tech [android.nfc.tech.NfcA, android.nfc.tech.MifareUltralight, android.nfc.tech.Ndef]}]
** Activity (main) Pause, UserClosed = false **
** Activity (main) Resume **
