2Pay - Payment Workflow

Hello Folks,
I have recently working on a self-initiated payment app called 2Pay. Basically, The concept is to provide smart payment system to rural areas who don't have the required hardware to scan barcodes and generate a bill. If we take the advantage of the mobile camera for this case, then the smart payment could be easier and accessible for everyone.

This is the payment flow for the concept. Full case study is coming soon, stay tuned.
