The existing interaction for cash withdrawal leaves user with options of withdrawing only round-figure amount, more precisely amount only in multiples of hundreds. In case of need, even when user has the balance account in account, can not withdraw the amount due to this withdrawal specification limitation.
There are quite a few problems identified with money withdrawal mechanism in ATMs. User can only withdraw amounts in multiples of hundreds; any amount not fitting this criterion (say Rs.123/-) yields an "invalid amount" error message. So even if there is money in the account user can not withdraw it. User should be empowered to withdraw the entire amount in account.
Another problem is even while the denominations are not supported format for entering desired amount is always 0.00 (o Rupees.00 Paisa).
When ATM machine cannot dispense lower denominations till paisa, one has to type in the above specified format; this is not only inconvenient for the user but also increases chance of error due to redundant typing. This contradicting behavior can definitely confuse naïve users.
Currently in most of the ATM machines, e.g. one of UTI bank ATMs, a person has to type in reverse order: first paisa towards higher denominations. This needs a little coping up for the novice and semi-literates.
