Microsoft in Windows phone 8.1 has added new Nfc related features including low level access(Non NDEF). I have Nokia Lumia 830 (PN547 NFC chipset is present in this device).Im not able to detect Nfc tag (ANT-7M24LR-A ,ISO15693) through Lumia 830, which im able to read/write using Nfc-V(ISO15693) in Android. I also have a Lumia 720 (old NFC hardware) but atleast it is able to detect the tag. Has anyone encountered this ? Whats the workaround ?
