Reward Points Redeemption Android App Development

I want one App where people could link whatever debit or credit cards they are using and our app should read only their reward points. Those reward points then they can redeem on our app for purchasing popcorns, burger, pizza, medicines. Whenever u shop anything using ur debit or credit cards of any banks, u get reward points. But most people are not aware of that and this is the reason rewards points get expired. There should be two versions, One for customer to redmeem their reward points and second for shopkeepers or merchants where customers will go and scan the QR code to redeem reward points. There should be admin panel also where everything could be monitored. If you think that you can do it then send me a message. Registration: Once you download the our Rewardz app, you can register your account in 4 simple steps:  Enter your debit or credit card or CIF number.  Enter the last 5 digits of your account number.  Enter the OTP sent to you on your registered email address and mobile number.  Create a username and set a password of your choice.
