What use would that be to anyone? I mean, what scam would be pulled by that means? Alice and Bob buy a ticket and go to a station. Alice uses the ticket to pass an entry gate, puts the ticket into an exit gate, retrieves it, passes it over the gateline to Bob, who then uses it to pass through an entry gate himself. It's passback, but slightly more subtle. A system which defeated passback might not defeat zig-zag. When I go through the barriers at Charing Cross platforms 1 - 4, just miss my train and have to head for platform 6 for the next one, I've never understood why the gates won't let me out. What scam is being prevented by it? As above. You might have punched out with the ticket, stayed on the fare-paid side of the gates, given it to one of your filthy lowlife accomplices, boarded a train, and let the ruffian wander off to use it again himself. tom -- Oh no - I've just turned my arse into a hand grenade! |
