Which one of the following links all the ATMs in India ?
Show answer
Answer: C. The National Payments Corporation of India (NPCI) runs the National Financial Switch, which links ATMs of almost all banks in India so cards work at any bank's ATM. So option C.
Watch for: RBI is the obvious regulator, but the network itself is run by NPCI.
Why the other options are wrong
- A. Wrong because the IBA is a banks' association and does not operate an ATM network.
- B. Wrong because NSDL is a securities depository, not a payment network.
- D. Wrong because RBI regulates payments but NPCI operates the ATM switch.
