Financial data sharing has undergone a significant transformation over the past few decades. From traditional methods of data exchange to the advent of open banking, the way financial institutions handle and share customer information has evolved to meet changing technological capabilities and regulatory requirements. This blog provides a historical overview of financial data sharing practices and examines the shift towards open banking.

Traditional methods of financial data sharing

1. Paper-based processes

In the early days of banking, financial data sharing was predominantly manual and paper-based.

Key characteristics:

Physical documents: customer information, transaction records, and financial statements were maintained as physical documents.

Manual transfers: data sharing involved physically transferring documents between departments or institutions, often through mail or courier services.

Limited access: data access was restricted to branch offices, and customers had to visit in person to perform transactions or request information.

Challenges:

Inefficiency: the manual process was time-consuming and prone to errors.

Security risks: physical documents were susceptible to loss, theft, and unauthorized access.

2. Early electronic systems

With the advent of computers, financial institutions began to digitize their data, leading to the development of early electronic systems for data sharing.

Key characteristics:

Centralized databases: banks used centralized databases to store customer information and transaction records.

Internal networks: data sharing within the institution was facilitated through internal networks, allowing faster access and processing.

Atm networks: the introduction of automated teller machines (atms) enabled customers to access their accounts and perform transactions electronically.

Challenges:

Interoperability issues: early electronic systems were often proprietary, making it difficult to share data between different institutions.

Limited external access: external data sharing was still limited, and customers had to rely on bank branches for many services.

The advent of online banking

1. Internet banking

The proliferation of the internet in the 1990s revolutionized financial data sharing, leading to the rise of online banking.

Key characteristics:

Online portals: banks launched online portals, allowing customers to access their accounts, view statements, and perform transactions from their computers.

Email communication: electronic statements and notifications were sent via email, reducing reliance on physical mail.

Enhanced convenience: customers could manage their finances from the comfort of their homes, improving convenience and accessibility.

Challenges:

Security concerns: the rise of online banking introduced new security risks, such as phishing attacks and data breaches.

User adoption: initial adoption was slow, as customers were wary of conducting financial transactions over the internet.

2. Mobile banking

The advent of smartphones and mobile applications further enhanced financial data sharing capabilities.

Key characteristics:

Mobile apps: banks developed mobile apps, providing customers with on-the-go access to their accounts and financial services.

Sms alerts: real-time transaction alerts and notifications were sent via sms, improving customer awareness and security.

Mobile payments: mobile payment solutions, such as apple pay and google wallet, allowed customers to make payments using their smartphones.

Challenges:

Device security: ensuring the security of financial data on mobile devices became a priority.

App usability: developing user-friendly mobile apps was crucial for customer adoption and satisfaction.
