Exampel code for communicating with DESFire under PC/SC with the PR533

[Lars Lars]

We are developing an Application for a computer Device (Panasonic FZ-M1) which has an inbuild RFID Reader With the PR533 chip.
We are using the Windows driver that is installed on the Device and the documentation we have is the UM-10463.

There is no referance to the handling of the DESFire card in this document. Is there some sample code available for handling of the DESFire card?

Hi Lars,

For C# programming on tablets and phones there is the Proximity API for Windows Phone. You will find a lot of examples how to use this interface in the net.

You will also find applications notes about the MIFARE DESFire EV1 on the NXP public documents server. For example:

Kind regards,

Hi,
And thank you for Your quick response.
This is not quite what we were looking for.

We try and rephrase:

References:
UM10463 PR533 Contactless Interface Controller, Rev. 1.2 - 10 November 2014, 230112 User Manual.

Problem:
We are trying to do the example descriped in the UM10463 document (rev 1.2) on page 55. The example is for an Ultralight card,
but what we need to do is to send commands to a Mifare Desfire 4k card and read the result.
We have changed the Switch Protocol command to 14443-4A.
Send seems to be O.K., but we get the TAG error on receive.
The error status is 6F 01 (PSCS part 3 Supplement Table3). Cannot find it there.
What does it mean?

Hi,

I will check the document UM10463. But please take in mind: the MIFARE Ultralight is not an export controlled product, but the MIFARE DESFire is an export controlled product. Therefore customers need to sign an NDA and we cannot discuss about detailed topics on a public server.

I come back later after I have studied the document and have valuable answers.

Hi again,

We have signed a NDA a while back so that should be o.k.
