Financial services secretary Rajiv Takru has said that he favours free ATM services as they exist now. Speaking to reporters in Mumbai on Thursday, Mr. Takru said that if these services are made expensive then customers may end up at bank counters and warned that a teller service is far more expensive than ATM service. He however clarified that no bank has approached the government seeking approval to raise ATM fees and said that a final decision in this regard will be taken by RBI.Admitting that ATM services should be sustainable, Mr. Takru said banks should look at ways to encourage customers to increase their ATM usage so as to make them profitable. Mr. Takru also called for a re-look at orders of some state governments asking banks to have round-the-clock security at ATMs.
