Problem:

Is it possible to copy information from a door lock card to an Android device and emulate that device as a card?

To Investigate:

  1. write a survey: Android card emulation for RFID technology

2 kinds of cards:

  • ID, taiwan, no encryption

  • IC: Mifare classic, plus, encrypted, classic with proprietary encryption algorithms, cracked, plus with AES.

TODO:

  • The mechanism for ID card

  • The mechanism for IC card

  • How to emulate a ID card

  • How to emulate a IC card
