(OP)
I'm trying to help my dad set up a barcode scanner that will open a valve on a irrigation system. We're planning on hooking it up to a computer so we can see who scans their card and at what time. We already have the valve system and we have plenty of laptops but I'm just not sure how to have a barcode scanner to do such a thing. I've worked with magnetic strips, (cards to unlock a magnetic lock) but this is an area that I've tried but been unsucessful.
ANY help in the right direction will be a great asset and I thank you in advance.
Thanks,
Dustin

Can you write code? Buy a barcode scanner, and as IRstuff suggests, write some code that reads the serial port. Now the tricky part - driving a valve motor from the laptop. You need an output relay board. Try here
www.measurementcomputing.com
more specifically, something like the followin might work, depending on the valve motor amperage requirements; you might need to use the output board to drive a larger relay.

They have other devices also, that can output an analog voltage or amperage (4-20mA), which is useful if your valve actuator is a proportional control device.
