Class

NFCNDEFReaderSession

A reader session for detecting NFC Data Exchange Format (NDEF) tags.

Declaration

@interface NFCNDEFReaderSession : NFCReaderSession

Overview

As with the NFCReaderSession base class, only one NFC NDEF reader session can be active in the system at a time. If you create an additional session, the system puts it in a queue and processes it in first-in, first-out (FIFO) order.
