No.  We have it for home cup games (I don't know how it works for PL games for non-ST holders) but the club has no visibility as to who scans in for an away game.  I guess there would need to be some co-operation between clubs to share that information - no idea how easy that would be, it doesn't sound like it should be that difficult as long as a club's entry system logs that info.
Thnk of the Bodo game the other week.  Away end half empty when the allocation was only 400ish to start with.  Tickets cost something like £28, with 5 points on offer.  It's a no brainer to apply, get the 5 points, but not bother with the expense and time of travelling out there, especially just a few months after we last played there.    It's how some of those at the top of the points table maintain their position there.
