SBI is followed by HDFC Bank (2.81 lakh), Axis Bank (2.58 lakh) and ICICI Bank (2 lakh), the RBI data showed.
"Being 'Banker to Every Indian', we are committed to promoting electronic payments in all parts of the country and provide strong push for achieving the goal of less-cash economy envisaged by the government," SBI said in a statement.
These four banks together contribute to more than three-fourths of the total 13.63 lakh PoS terminals deployed in the country.
During 2015-16, almost 40 per cent of the growth of acquiring industry in terms of number of terminals was driven by SBI alone by deploying more than 1 lakh PoS terminals.
More than 30,000 of these terminals are contactless terminals.
In the current fiscal, the bank plans to add further one lakh PoS terminals to enhance card acceptance infrastructure particularly in tier-3 and below centres, it said.
