It would probably be easier to handle paper tape. Old ASR-33 teletypes can often be picked up for about $10 at swap meets. A more elegant solution would be a magnetic stripe reader. You can make a reader using a tape head and some Plexiglas or pc board material. Crooks use homemade reader/writers to copy codes onto cards this way. The cards cost pennies.

I have 30 to 50 boxes of computers cards stored that I would like to read. What I would like to find, is some "simple" device to read them, shove the data out a port (serial or parallel) and let one of my computers that inhabit my basement catch the stuff. One approach is to find an old IBM Punch & Reader units. Another is to build a little LED/photosenser array that the cards would be moved past by hand (My fingers hurts just thinking about it....). Any suggestions? Sources? Reply to me or to the net if you come up with answer to both Paul's and my projects.
