5.4 USER NDEF

The USER NDEF area allows the user to store a string of up to 64 characters starting at

page 0x18 and ending at page 0x27.

This area can for instance be used by the system integrator to provide information on the

intended installation location or by the installer to leave information about the installation.

PTM 535BZ will neither modify nor interpret the content of this area.

5.5 NFC HEADER

The NFC HEADER area contains information about the NFC memory structure and can

therefore be used to distinguish between different NFC memory layouts.
