Read Google Smart Tag using PN7642

Hi Experts,

I need your help to develop firmware to read a tag saved in an Android phone application inside Google Wallet.

I haven't found any documents related to it or a tutorial video. Can you provide me a document on how to read a tag saved in a phone using MIFARE DESFire? I have already bought the PN76 evaluation board.

Thanks & Regards,
Yash

Unfortuantely, Goolge Wallet topics are quite restricted.

This is a mass-market support channel and, we don't have the support resources to provide the proper information. I will have to kindly ask you to please contact your NXP sales. Still, for a direct support is recommended to please contact the MIFARE2GO team to the following mail: mifare@nxp.com
