In everyday life people are using Plastic cards (Master Card, VISA etc..). It is difficult to remember the PIN code for many people while paying at the shop. So most of them pay by cash.
To solve this problem, I have an idea of developing a mobile application that will store your ATM cards as fingerprints. So you can pay by your Finger Print. So no need of ATM cards.
Why this idea now?
Simple. From the middle of last year, many mobile companies are releasing the mobile that has finger print sensor. So by the end there will lot of mobile with finger print sensors. This is the right time to develop this idea.
