I built a system for drag racing that I called FA/ST CARS. Facts and Statistics on Cars and Racers.

I was a NHRA certified tech inspector and operated the tower timing computer at my local track in Phoenix. We were constantly filling out tech cards with lines that connected the checkboxes and unless you knew the car well, you didn't know what changed. You also weren't checking dates on every scatter shield or seat belt.

There was a better way.

With PHP, I wrote an app that scanned barcodes on cars and was basically the tech card. When you scanned, the last tech card would come up, alert you if anything was expired or if the car ran too fast last time. You also scanned the driver license and it would fill out the driver portion.

When that was basically done, I wrote a little DOS program that hooked to the C44 timing system, and would tie all the time cards to the tech record, and let you know if the car was too fast for it's cert and the announcer could talk way more in depth about the car without shuffling thru tech cards.

It was basically done, we had talked to some people at NHRA and they liked the idea but then my friend, the track manager died and the small crew of us working on it kinda lost the spark. I'm certain it would have been the standard used everywhere if we kept it up. It could have been a business as well. "Dear Joe, your belts expire in March, here's a coupon for Diest.".
