In the winter I organize esk8 karting rides. We rent an entire circuit for 4-6 hours.
Now I am looking for a timing system. So that every person who drives knows his lap time.
I was thinking of an NFC system, where I gave every man a sticker that he had to put on his helmet, set an antenna + reader at the start / finish. And let it upload those results directly to a cheap website.
Any tips? Any guys with experience?
