Need Program written for amatuer

Evening /prog/ I have a task for you. I'm in highschool and know nothing of real world programming. Know only Visual Basic, Pascal and Actionscript.

I've been hired by the school to make a swipe card system and need to make the program to run it.

Currently have:
Card scanners that work.
Cards to scan
2 x Touch screen computers

I need to somehow be able for them to scan there card and be signed in at the school, but i also need them to be able to sign out.

Having the information in access would create brownie points for the teacher. I currently have a list of names and the barcode number that corresponds to them.

Can you help?

I've been hired because i'm one of only 3 people in the current programming class, and the teachers with the skills to do it are to lazy to do it.
