As I know, there is built-in NFC chip at the back of mobile phone such as samsung. So I would like to read the built-in chip info from that mobile phone. Is that possible or silly question?

  • Why do you think that your device has a NFC-Tag? Devices have normally a NFC-Reader with which you can read/write NFC-Tags

  • After googling, I found that Android bean use NFC chip to transfer data. And S Bean use wifi-direct. Is that right? Mar 30 '16 at 10:08
  • You mean Android Beam and S Beam. Yes S Beam uses wifi-direct and Android Beam uses NFC.

  • So is there any chip on the back of phone to use Android bean feature? Mar 30 '16 at 10:16
  • 1
    What are you actually trying to achieve? There's no "fixed data" to read like with an NFC tag, the phone just transmits the data from some running app.

To close this. There isn't a NFC-Tag (as the hardwaredevice) but there is a chip which can act like a NFC-Tag and provide data. The question above should be answered with that.

  • I found the one of nfc modes: NFC card mode in phone. It is used as a identifier for phone. Apr 29 '16 at 3:31
