Problem Statement
In Hong Kong, we have a lot e-wallet options, such as WeChat Pay, Alipay, PayMe, BoC Pay and more. While these e-wallets have made digital payments more accessible, they have also created friction for both merchants and users.
For Merchants
Merchants must collaborate with multiple payment providers and display multiple QR codes for each provider leading to operational complexity and higher costs
For Users
Consumers must juggle multiple apps depending on what the merchant accepts which is inconvenient as they must managing multiple wallets
Unified QR Code Payment System
Solution
a unique QR code for each transaction and customers can use their preferred e-wallet app to scan the QR code and complete the payment
- Eliminate the need for merchants to collaborate with multiple payment providers and display multiple QR codes
- Users can choose their preferred e-wallet app for transactions without being limited by the merchant’s accepted payment methods
Project Objective
Develop a proof-of-concept prototype of the Unified QR Code Payment System that generates dynamic QR code and allows simulated e-wallets to scan and make payments
