Why need of automated teller machine?

An Automated Teller Machine or an ATM as it is commonly called is a machine that provides banking functions to customers. It is needed because:

1. Not all bank branches are open on all days of the week

2. Customers may need banking functions even on holidays and weekends

3. Customers may not be in a position to visit the bank everytime they want to withdraw or deposit money

So, the ATMs help banks to provide banking services to their customers 24*7 on all 365 days of the year.
