In the era of digital evolution, banking is no longer a matter of standing in a queue at a branch, while traditional financial services have morphed into more convenient and accessible forms. Within recent innovations, core banking has been a driver of transformation, but what is core banking and why is it revolutionary for banks and its customers? 

Let’s break it all down – the definition of core banking, core banking solution and how does it work, the technology behind it, and why core banking software matters and the main core banking solution features and benefits.

What Exactly Is Core Banking?

Core banking is a term used by banks to refer to the core system which they employ to provide customers with real time service from any branch or through any digital channel. In other words, core banking is the core of banking—it performs all banking operations including deposits, loan disbursements, withdrawals, account servicing and transactions. 

To use your phone to complete your transactions in a specific location, you must have access to and be connected to a central server. In simpler terms all banking activity is managed centrally and executed in real time, regardless of whether you are sitting in Mumbai, Delhi, or using your mobile app in a village. That’s why in the CBS in banking sector, the challenges of the isolated branch system are resolved on the same network.

Thus, when you transfer funds through UPI, check your balance online, or do an eKYC at any branch, that’s all enabled by core banking architecture.

Why Do We Need Core Banking Technology?

Traditional banking was fragmented; each branch maintained its own database. This meant significant banking activities could only be performed at a customer’s home branch. Not really achievable back in the day. 

Enter core banking technology, which offers a unified platform. Core banking allowed for banks to be less fragmented so they could develop faster, more reliable services for their customers. 

Here why CBS in banking sector is now essential: 

While transferring and depositing money, or withdrawing cash from an ATM, CBS provides a way to ensure real-time updates are available for these transactions. 

• Anywhere banking implies a customer can go to any branch of a bank or log-in from any device to access their account rather than being limited to only their “home branch.” 
• With core banking services, banks can provide customer-centric services. The features and benefits of core banking solutions provide a better understanding of their customers and ability to serve them in a much better manner. i.e. Instant loans or attractive offers.
•  In times of increased financial scrutiny, core banking software provides support for regulatory compliance. It is very easy to maintain accurate records and all necessary backups, and to align with the Guidelines provided by the Reserve Bank of India. 
• Core banking system has become integrated into many fintech solutions available today. For example, a bank can easily integrate with the latest payment apps, investment platforms, and mobile wallets. 

In short, including a core banking architecture into today’s digital banking concept allows for the financial world to reinvent itself and innovate.

Core Banking Architecture – A Quick Overview

There is a foundation for every seamless banking experience. Below is the typical layout of the core banking architecture:
