Payment System Architecture: Connecting BANK, Cloud, and Merchant ECR

This Flowchart illustrates the payment process using an Emtech Interface, showing the interaction between different entities such as Bank Base, Cloud, and Merchant QR. The process starts with the payment initiation via Way 4, followed by communication with the Bank Base and the Cloud via Public APIs (HTTPS). The Emtech Interface facilitates the transaction through secure API connections, allowing seamless interaction between the merchant and the bank. This Flowchart is ideal for professionals in payment processing and fintech sectors, providing a clear visual representation of how payment data flows through the system. Tools like EdrawMax can be used to design and customize such Flowcharts for payment systems, improving transaction transparency and security.
