We already have them here! (Score 1)

Here in Brazil we have had these multifunctional ATM machines for a long time (almost ten years, that's as far as I can remember). We can use them to pay any bill (they have a barcode reader), make deposits (they can accept money but the amount is manually checked and validated afterwards), recharge a prepaid cellphone, pay taxes, transfer money, invest in funds (as long as no signed papers as required) and so on.

There is a local company which manufactures multifunctional ATMs for all those purposes, some of them even have a full keyboard (I have used one once to set my internet password).

Of course all that is just a matter of savings to the banks, since an ATM is much cheaper than an employee.
