You should import pax device library. Than you will be able to read Mifare card with custom APDU commands like you have already did for public android mobile phone.

NFC is not provided out of the box in PAX devices unlike mobile android phones.

Then you can read Mifare card from Contactless Card Reader Interface of device with sending custom APDU commands over a method provided by pax device library.
