**UPDATED DESCRIPTION** **** PLEASE READ CAREFULLY AND UNDERSTAND IT BEFORE CONTACTING ME*** *** I WILL CHAT WITH YOU ONLY IF YOU READ ABOUT IT, DON'T GIVE YOUR COPY PASTE HISTORY *** ------------------------------------------------------------------------------------------------------------------------ Dear All, I want to implement an idea on the smartphones (IOS & ANDRIOD). I will brief the idea by an example: Suppose you are going to hypermarket, you buy some products and finish, now for the annoying part which is cashier queue waiting, how about you scan the product by your cellphone and make the payment? without going and wait in the cashier queue? How the store owner will know that you have paid? I don't have a solid answer now but it could be done by using a camera at the exist to check your code which will verify the payment. If you have another Idea (BESIDE THE CAMERA) we can discuss it, but please read first before you contact me. Regards, Sounds good right? Can you implement it?
