The apps looking cool.but no hardware to try it. i would like to build a games that can play with real figure. the idea is that,...something like pocket monster. when you open the games and wake up the figure, then the character can be show inside the games. How can I do?
Umm... are you going to make a arcade with card?
To build the hardware, you'll need to implement a hardware with RFID + data connection(like Bluetooth or USB or Serial port...) function. You can try to design these features on Arduino.
It sounds cool. And I think you don't need to use Bluetooth Low Energy. BT3.0 already fulfills your need for this project, and you can buy a BT module to connect your Arduino & Android. Below is my proprietary Bluetooth Arduino Joystick.
