(T)errible user interface <-- HAHAH!!
I finally used cash to buy a Charlie Card last night, since they're finally converting Porter Square. (In the past, I've just traded tokens for single-use tickets.)
It took a long time before I realized that the ticket machine won't take your cash bills until you press a button located nowhere near the bill feed telling it that you would like to give it some cash.
That's jaw-droppingly bad UI along multiple axes.
(a) The feed serves no purpose other than taking your money. It does not need to be modal. It is safe to assume that a customer will not insert money unless they wish to buy something. Instead of refusing the money, it should graciously accept it and then enter a dialog with the customer about what they would like to buy.
(b) For every bill-accepting vending machine that I've ever seen, the way you initiate a transaction is feeding it some dough. There are decades of UI tradition in play here; it's what people expect. If you, as a machine, act differently, customers will assume you are broken. As did I. Only when I stepped back and looked for other options did I notice the instructions telling me to poke the screen first.
After finally buying a hot new card, I proceeded to try feeding it through the turnstile, where it made a farting noise, and an integral screen lit up with a message telling me to re-insert it. So I did. Fart. OK, turnstile broken! Try next one over. Fart. WTF? Oh, I see, I'm putting the card in upside-down, because the up-side is clearly the plain white one with a large orange arrow on it, and not the colorful one with three small black arrows on it. Folks, I can understand the cost savings of not putting a strip reader on both sides of the slot, but would it have killed you to clearly print which side was up? (And which side was down?)
Ugh... what a disaster.
radiotelescope adds that the turnstiles, if they drain your ticket of the last of its funds, will hand it back to you anyway. Other cities' subways will chew up a newly empty ticket, say THANK YOU and let you through. Our city's subway, on the other hand, is destined to have a floor littered with dead tickets.
I take it back if the machines give you a bonus for recharging a ticket, like (for example) the LAUNDR-O-MAT does with its cash cards. Otherwise, why would anyone want to bother recharging an empty ticket when it's easier to just buy a new one?
