[IxDA Discuss] ATM interaction design

[pauric]

Peeve: Any ATM flow that gives you cash before completing its
interaction with you.

That is, cash before it gives you your card back, or ending secure
access to your accounts.

The primary goal for the majority of people is to get cash, in
distracted or stressfull situations such as wandering kids, late for
appointments, drunk on a night out, baked on the way to your dealer
etc,  people have been known to walk away from the machine after
completing their primary goal.

Leaving the machine prompt at 'would you like to complete another
transaction?' leaving the card in the machine. Seems obliviously
stupid but I've seen it happen and done it myself.

80/20 rule, dont stick steps on for the 20 after the 80 have
completed.  I would say in this case, make the 20 start again.
