Government IT projects always run over budget, past their deadline and the final product only has half of the intended features - why would a project that looks bigger than anything done before succeed when the government has failed so many times before.
I had to get up in the morning at ten o'clock at night, half an hour before I went to bed, eat a lump of cold poison, work twenty-nine hours a day down mill, and pay mill owner for permission to come to work, and when we got home, our Dad would kill us, and dance about on our graves singing "Hallelujah." But you try and tell the young people today that... and they won't believe ya.
That would only be the case if you let people push between the members of the group, which means that passing your phone back every time is the very worst case scenario - the average case would be much closer to only having to scan your phone once.
I have just done a university coursework with a very similar system to this using NFC instead of 2D barcodes and if it is set up correctly it can be a lot quicker using this system than having the queue for a paper ticket.
The problem with (some) textbooks is that they rely quite heavily on pictures to help explain things (e.g. A lot of biology textbooks) which may require the ability to display colour, which the sony device can't.
If the number of tickets associated with the phone is stored in a database, the database can be updated every time someone uses the turnstile. If a second person scans their phone, the database would update their record. All you would need to do is scan your phone again and it would start accessing your database record again.
It should be possible to encode the number of tickets in some way in the barcode, so if you book 5 tickets, swiping the phone once will allow the turnstile to open 5 times.
I think that Near Field Communication (NFC) would be a more secure way of implementing a similar system, and there are
phones that can use NFC already. Each NFC tag has a unique ID, which (as far as i'm aware) cannot be changed, so unless someone steals the phone they can't use the ticket.
