This lesson focuses on the digital infrastructure that enables retail payment processing, including internet banking, mobile apps, and the technology that connects merchants to the banking system.

7.1 Introduction to Digital Banking Channels
Digital banking encompasses the delivery of banking services through electronic channels, moving beyond traditional branch banking. This includes internet banking (via web portals), mobile banking apps, and digital TV banking . Understanding these channels is essential, as they are often the primary interface for retail customers.

7.2 Payment Gateways and Their Role
A payment gateway is a critical piece of technology that acts as an intermediary between a merchant’s website and the financial networks that process a transaction. It securely authorizes and processes payments, supporting credit cards, debit cards, and other digital payment methods . In the broader architecture, this is part of a payment system that provides the mechanism for transferring value between payer and beneficiary .

7.3 Marketing and Management of Digital Products
Effective banking institutions actively market their digital products to promote adoption . Understanding the application architecture, which includes the computer networking and banking products that underpin digital services, is key to managing and enhancing the customer experience . The ease of use and security of apps are critical factors in customer acquisition and retention .

7.4 Emerging Payment Technologies
The digital landscape is constantly evolving. This includes the adoption of contactless payments (NFC technology) and the rise of mobile wallets . A deeper understanding of electronic payment systems considers various types, such as credit cards, debit cards, online cash, and mediating services like PayPal. These represent a fundamental shift from paper-based to electronic value transfer .
