The National Financial Switch is a vital part of our country's financial infrastructure, allowing banks to process transactions efficiently and securely.
It's a centralized switch that connects all major banks in the country, enabling them to share information and facilitate transactions. The switch is operated by a single entity, which ensures that transactions are processed uniformly across the country.
One of the key benefits of the National Financial Switch is that it reduces the time and cost associated with processing transactions. This is because banks no longer need to maintain their own separate systems, which can be expensive and time-consuming to maintain.

History and Overview
The National Financial Switch has a rich history that dates back to 2004 when it was launched by the IDRBT, connecting ATMs of three banks: Corporation Bank, Bank of Baroda, and ICICI Bank.
By 2009, the network had grown to connect 49,880 ATMs of 37 banks, making it the largest network of shared ATMs in the country. This rapid growth was a testament to the need for a unified payment system in India.
The IDRBT decided to hive off its operational role on ATM switching to focus on research and development, and the National Payments Corporation of India (NPCI) took over the operations of the National Financial Switch in 2009.

Any bank providing core banking services with 24x7 transaction banking capabilities can join the National Financial Switch through a sponsor bank, allowing non-scheduled Urban Co-operative Banks (UCBs) and Regional Rural Banks (RRBs) to access the national network of over 103,000 ATMs.
The National Financial Switch was also instrumental in increasing financial inclusion in Zambia, where cash remained the predominant medium of exchange until the project was initiated in 2013.
