All you have to do is point the phone camera at the banknote and keep it at a certain distance. The application reads the value of the banknote by voice.
There is also vibration feedback. One to three short vibrations represent $10, $20, and $50, respectively; one to three longer vibrations represent $100, $500, and $1,000.
