This might seem a little far-fetched, but it would allow you to use 100%
off-the-shelf hardware... What about a receipt printer? You could set up
the software to automatically print out a receipt with the rider's name
and time as soon as his/her barcode is scanned...

Heck, if you wanted to take this a little further you could get a
surplus outdoor printer like the ones at parking garages, and have it
spit out a ticket as they ride out of the tent...
