The code below shows how to handle an error: public void DidInvalidate(NFCNdefReaderSession session, NSError error) The app ceased to be in the foreground.Invalidation can occur for a number of reasons: This is set using the third parameter of the Start method (explained in step 2). This method may be called multiple times (and an array of messages may be passed in) if the session allows for multiple tag reads.
