• 2.1 The Traditional Banking Era

For centuries, banking was a physical, location-based service . The traditional bank operated through a network of branches, where customers conducted all their financial activities in person. Services were delivered during set business hours, and access was limited by geography . This model is often described as “brick-and-mortar” banking.

Key characteristics included:

  • Branch-Centric: The primary and often only point of customer interaction.

  • Paper-Based: Reliance on physical documentation for opening accounts, processing transactions, and record-keeping .

  • Limited Access: Services available only during business hours and within geographic proximity to a branch.

The core banking model relied on centralised systems where all transactions were processed through a central mainframe, and branch networks were the primary distribution channel.

2.2 The Introduction of Electronic Banking (1960s–1990s)

The first major shift away from purely physical banking came with the introduction of electronic banking. Key milestones included:

  • ATMs (1960s): Allowed customers to perform basic transactions outside branch hours .

  • Card Payments (1970s–1980s): Credit and debit cards enabled electronic payments without cash or cheques.

  • Telephone Banking (1980s): Allowed customers to perform transactions via phone.

  • Internet Banking (1990s): Enabled customers to access accounts and perform transactions via the web.

These innovations began the process of digitising banking but were still largely extensions of the branch-based model.

2.3 The Digital-First and Mobile Era (2000s–Present)

The advent of smartphones and mobile internet transformed banking from a digitised version of branch banking to a truly digital-first experience. Key developments include:

  • Mobile Banking: Full-service banking through mobile apps, enabling transactions anytime, anywhere .

  • Digital-Only Banks (Neobanks): Banks with no physical branches, operating entirely online .

  • Fintech Disruption: Technology startups offering specialised financial services, often with superior user experience .

  • Open Banking: Allowing third-party providers to access bank data through APIs, enabling new services and business models .

  • Real-Time Payments: 24/7 instant fund transfers, eliminating traditional processing delays .
