People must be still remembering how they used to do any transaction in a bank. To withdraw money, they had to stand in a queue with a withdrawal form or a check. When his/her turn would come, the clerk would first check your signature by searching through a number of registers to locate your specimen signature and to verify it. Similarly, another search through bank ledgers would be done to locate the page containing the details of your account. Thereafter, the necessary entries would be made and then would be forwarded to another person who would authorize the payment.
Only after all these activities are completed successfully, you would be able to withdraw cash from your account. Another difficulty was that you could withdraw money only during the working hours of the bank. It would not be possible for you to withdraw money on a holiday or in the night.
