When the guard scans your Aztec code on your ticket, what kind of information is taken from it and does that information go anywhere? If so, what is that information used for?

Thanks

Hi

The location of your ticket being scanned is recorded. Gatelines can scan these, as well as humans (on board staff, or at gatelines with manual scanners). The scan record is then sent to a database for that operator. The scan record is also available to the retailer. There are various other things that go on too.

It's an Aztec barcode, not a QR code, incidentally.

Individual eTVDs (online databases) can be shared with other TOC and retailer eTVDs. It's used for revenue protection and various other reasons.

Various checks happen
1) is the barcode valid (ie is it home generated or altered)
2) has the ticket been used before (or been refunded / cancelled)
3) it electronically endorses the ticket as being used (either on train or at a barrier and for barriers it’s either entry or exit)
4) it records who scanned it (person or machine)
5) what time it was scanned (sometimes the service as well)

The information is saved on a database to which all operators save details and can access details to varying degrees

However, annoyingly, each TOC has been allowed to develop their own scanning software rather than the Rail Delivery group insisting that their should be certain standards.

For example, if you are travelling on a First Group TOC, their hand hand scanners (set to train mode) won’t bat an eye if you use the ticket at the electronic ticket gates. However they will throw a wobbly if your ticket was previously scanned by STM (Northern Staff) at a barrier as the App that they use isn’t as intelligent as the First Group one. The Northern scanner “just” scans and (AFAIK) doesn’t has gate modes or train modes etc.

It does have a station/train mode - I set it to the train I'm working and it tells me if advance tickets are valid on that service, for example. Not sure how that comes across to other operators though.
