Over the last several months these machines have been appearing at bus-stops throughout the city and now one has made it to my stop.
According to the Lothian Buses website they have been a great success and are very popular but so far I have not seen a solitary soul make use of them. I don't find that surprising given the list of things this machine does not do. It does not:

• take credit or debit cards
• take banknotes
• give change
• allow you to overpay by more than 20p
• dispense more than one ticket per transaction
• give a ticket for tomorrow or even much later today - get aboard in 40 minutes or else

Now I'm all in favour of off bus ticketing but it has to be a bit more sophisticated than this. Think of a family of four having a day out in Edinburgh. Currently that's nine quid but to get those tickets they have to assemble a bucketful of coins and conduct four transactions. Have the bus bosses never set foot on the continent?

Just wait till you are 60 folks, no problem then.
