People pay ATTENTION when it's about their money!

Interaction with ATM is limited to a short period, and one operation.

Interaction with ATM is motivated with immediate need.

ATM only offers basic & hierarchical & expectable choice:
 - what is your code ? (keyboard with 10 digits, 2 extra key (ok, cancel))
 - how much do you want ? (enter number or push 1 button)
 - do you agree with the fee ? (yes/no)


Compare to a programming computer's environment: keyboard is 105+ keys,
there is no questions, and people do not even think about the
specifications of what they will be doing for the next week!
