Correct Option
The National Payments Corporation of India (NPCI) manages the National Financial Switch (NFS), which serves as the central network linking all Automated Teller Machines (ATMs) across India. This infrastructure enables interoperability, allowing customers of any bank to conduct transactions at ATMs of other banks. The NFS was initially developed by the Institute for Development and Research in Banking Technology (IDRBT), an initiative of the Reserve Bank of India, before NPCI assumed its operations in 2009.
Incorrect Options
- Indian Banks' Association (IBA) is a body representing banks in India, primarily involved in policy advocacy, coordination, and promoting best practices within the banking sector. It does not operate or manage ATM networks.
- National Securities Depository Limited (NSDL) provides dematerialisation and settlement services for securities in the Indian capital market. Its functions are distinct from the management of interbank ATM infrastructure.
- The Reserve Bank of India (RBI) is the central bank and the primary regulator of the banking system in India. While it oversees and regulates banking operations, including ATMs, it does not directly operate the technical switch that connects all ATMs. This operational responsibility rests with entities like NPCI.
