Understanding MIFARE DESFire as Type 4 Tag

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.

The NXP product MIFARE DESFire EV1 is compatible with the "NFC Forum Type 4 Tag Operation" version 2.0 technical specification and the Type 4 Tag platform. This document extends the information and the functionalities about how the NFC Forum device manages the MIFARE DESFire EV1 product as an NFC Forum Type 4 Tag platform.
