Money will be paid after the succesful testing of money transaction through QR Code scanning by our android app. Project award and milestone creation will be done after successful testing of App. If you want to work on this project then you will have to agree my terms and conditions. I need an Android for scanning QR code for money transactions. We have developed one web app for generating Discount coupons. Our discount coupons will be having QR codes. We want that our merchants accept those coupons. For redeeming those coupons, they just open our Android app and scan the QR code and one secret Pin or Otp should be sent on registered mobile number and after entering that secret Pin or otp money should be immediately deposited in merchant account. Api integration will be done by developer only. Source code will be our property. Designing will be done at your end only.
