"Low Tech" Bar Code Reader -- Possible?

Hello Microcontroller Loving Friends,
Would it be feasible or possible to create a 'low tech' bar code reader using QTI sensors?
Not much like a 'real' bar code, really, but something similar - on a different scale. For example, if I created a large strip of paper with areas of black & white, and assuming I could control the path of the "scan", couldn't something similar to a bar code reader be created using this technique?
I'm thinking of making a bar code reader robot and locating it inside one of the many plexiglass display cases in the main entrance to our school during National Robotics Week and then offering students clues to a puzzle so they can make a key - a barcode key - to "unlock" the robot and watch it do something - light up LEDs, beep, dance, give them a pass to skip school, whatever.
Thanks,
Scope
