Startup Idea : Cash from ATM without cards

In most of the developing countries, cash is the most popular form of transaction and ATMs are best and fastest way to get cash. But the only thing is to carry a card with you all the time. But if you somehow lose your wallet or card and in dire need of cash, then you have on option.What my idea is, to have an option to use your net banking account to get cash from ATMs. All you have to do is visit an ATM and use its interface to fill your account details and get cash, just like you do while paying online to e-commerce sites, but instead you get cash.
