The user can now enter data into the bottom ‘Write’ window and press the Write button to write NDEF message into the tag. When this occurs, the screen will quickly flip to Write NDEF, then the user can either press the Read button or remove the tag from the reader/writer antenna and re-present the tag to get the NDEF message read back. The NDEF size is now 236 bytes (out of 250 bytes available on the tag) and the message is displayed.
