In a written reply to the Lok Sabha, Minister of State for Finance Santosh Kumar Gangwar said RBI has informed that it recently conducted a "representative sample survey" of about 4,000 ATMs situated in metro, semi-urban, urban and rural areas across the country.
"Primary findings of the survey has revealed that around 30 per cent of the ATMs (600) of public sector banks and 10 per cent (100) ATMs of private sector banks surveyed were non functioning/mal-functioning," he said.
"The report does not explicitly capture bank-wise data on non-functioning/mal-functioning of ATMs surveyed," the minister said.
