    I do understand that ATM's have become user friendly and for those who does not have time to do banking leisurely can use the ATM facility even at the odd hours of the day and thus one can ensure 24 hours banking at our disposal. With the advent of ATM's many people are not carrying the hard cash with them but simply carry the bank cards through which they can withdraw the money at any given time. But care must be taken that you withdraw the money from your bank ATM's only otherwise service charges may be levied. More over I want to make a suggestion here that every ATM must have a hotline facility to the branch or the customer care center where in certain problems faced during withdrawal or transactions could be redressed. For example the card might have been read, but we wont get the cash or we type higher denomination and got lesser cash etc. Some ATM's have facility to withdraw only in the denomination of 500 and not 100. So all these problems for the new user are not addressed and he has to wait for next day when the bank opens to tell his complaints.
