With the rise in living standards, stores are becoming larger and more diverse in their offerings. As a result, both merchants and customers are concerned about developing a simple, quick, and convenient shopping guide system. For the consumer giving credit card information, security has become a big concern. Other payment methods, such as using USSD, have numerous flaws, including lack of reliability, memory, and vulnerability to hackers. As a result, it is critical to develop a system for establishing a secure payment method. Identity theft, merchant-related scams, and customer data security are all addressed by the method. The established system also aids in keeping excellent records and tracking available products in the store, as well as product and account/transaction information. The proposed system is the implementation of a secure operational paradigm for mobile payment based on Service-Oriented architecture and the Quick Response Mechanism.
