6. NFC interface

03925 implements NFC Forum Type 2 Tag functionality as specified in the ISO/IEC 14443 Part 2 and 3 standards using an NXP NT3H2111 Mifare Ultralight tag.
This NFC functionality can be used to access (read and write) the 03925 configuration memory and thereby configure the device as described in the following chapters.
Chapter 6.1 below gives an introduction to the NFC functionality and options to use the NFC interface.
For in-depth support for integrating the NXP NT3H2111 NFC functionality into PC or smartphone SW please contact NXP technical support.

6.1 Using the NFC interface

Using the NFC interface requires the following:

■

NFC reader (either PC USB accessory or suitable smartphone / tablet)

■

NFC SW with read, write, PIN lock, PIN unlock and PIN change functionality

6.2 NFC interface functions

For a detailed description about the NFC functionality, please refer to the ISO/IEC 14443 standard.
For specific implementation aspects related to the NXP implementation in NT3H2111, please refer to the NXP documentation which at the time of writing was available
under this link:http://cache.nxp.com/documents/data_sheet/NT3H2111_2211.pdf
The following chapters summarize the different functions for reference purposes.
