And how do they get into the park? You have the tickets not them. Since you used your finger for their passes if you go out and give them the tickets later their tickets will not work as the scanner will not match their finger with the tickets. So you have the whole family show I.D.'s while a number of people behind you are fuming as the whole process you used ties the line up for a long time.
If the idea that the biometrics between passes bought at the same time with the same credit card are linked, your point is moot.
And I believe they HAVE to be linked... The confusion caused at the turnstyles constantly by mom and dad accidentally swapping passes before entering (not to mention the kids) would create more of a bottleneck than your concern above.
It makes sense that they would be tied to each credit card transaction.
Meaning in theory what I and unkadug suggested would work.
When you buy tickets from the automated machines, or when you buy them from a ticket booth at the TTC, are names even assigned to the tickets?? I didn't think they were. I thought you walked up to the automated ticket machines, buy however many identical tickets you need, and off you go. If there are no names on them, the biometrics would HAVE to be linked, because there's no way to know which ticket was for which... They would just be treated as a group of tickets for a group of people, all bought at the same time. The first time a finger scan was done on each ticket, it would go into the "approved" group of biometrics.
Unless I'm wrong, and every single ticket media always has to have an individual name on it to tie it to a specific person (even those bought at the booths and automated machines. It's been a few years since I've used those automated machines at the TTC so I don't remember for sure.
Either way, you can bet I'm going to test this next time I'm there, just because I'm curious.
