Overview

This solution implements a magnetic card reader for smart phones based on MSP430G2432 microcontroller. The reader is designed for reading out the content of the bank card based on ISO7811 and sending the card's information (such as card ID and expiration data, etc.) back to the mobile host.

Features
  • Ultra-low power: average 1uA standby and <2mA for reading (information can be stored for years)
  • Low cost design using an MSP430 Value Line MCU, a single channel op-amp, and a few passive components
  • Small form factor
  • Easy to integrate into a full system
  • Android test tool application provided"
