ATM software is an example of something that really is becoming needlessly over-engineered. For example, a week or so ago I encountered an ATM that prompted me for my e-mail address to e-mail a receipt (or, as smaller, secondary options, buttons for printing a receipt or declining a receipt all together). It really rubbed me the wrong way. Who is trying to collect my e-mail address? How are they storing it? What else will they use it for? Why is this the default option?
