NTAGI2C TAG ,Andriod Studio, MIFARE SDK Lite

Forum / MIFARE SDK / NTAGI2C TAG ,Andriod Studio, MIFARE SDK Lite

  • 30. June 2015 at 12:30
    I am testing a small app that uses the MIFARE SDK Lite with the NTAG12C tag. The tutorial i am following is
    UM10809-Getting Started with MIFARE SDK from the mifare. However i am having problem getting
    the application to read my Tag, the Nxpnfcliblitecallback () callback method is the issue i believe.
