The National Payments Corporation of India (NPCI) is responsible for linking all ATMs in India. This is primarily done through the National Financial Switch (NFS), which is the largest network of shared Automated Teller Machines in the country. The NFS facilitates seamless inter-bank transactions, allowing customers to use any bank's ATM for services such as cash withdrawal and balance enquiry, thereby ensuring nationwide interoperability and greater financial inclusion.
