In the meanwhile, by connecting to the KL-95018 Antenna Module as reader/writer, we are able to read and. Formats a tag as NDEF, write a NdefMessage, and make read-only. This is a multi-step process, an IOException is thrown if any one step fails. The card is left in a read-only state if this method returns successfully. This is an I/O operation and will block until complete The NFC Forum has defined a data format called NDEF to store different kind of application data. NDEF structured data may be stored inside contactless tag. In the NFC Forum the NFC Forum Type 4 Tag Operation version 2.0 technical specification has been developed to describe how the reader device (called NFC Forum device) can store NDEF data inside an NFC Forum Type 4 Tag platform.
