Hello, I'm also interested in reading an Android NFC phone with any NFC reader. I don't really see what this means in the documentation :
"The NFC device that is receiving the pushed data (the scanned device) must support the com.android.npp NDEF push protocol" Is the scanned device the phone or the other device (a NFC reader in my case) ? Does that mean the two devices involved in the P2P communication must be Android devices ? Thanks for your help.
