public class NFCReaderSession
extends NSObject
implements NFCReaderSession
```
NFCReaderSession This represents a NFC reader session for processing tags; this base class cannot be instantiate. Only one NFCReaderSession can be active at any time in the system. Subsequent opened sessions will get queued up and processed by the system in FIFO order.
