The abstract base class that represents a reader session for detecting NFC tags.


class NFCReaderSession : NSObject


You do not create instances of this class. Instead, you create and use an instance of NFCNDEFReaderSession. Only one reader session of any type can be active in the system at a time. The system puts additional sessions on a queue and processes them in FIFO order.
