This is interesting, i built similar for retail environments, oneoffs for events or windows or whatnot. I'm sure you could probably get away with a few terrible webcams per lane for ball tracking it's pretty much a perfect environment. A totally flat level lit are with very little noise with one circular blob moving through it. Might be an issue if you do the ever popular blacklight lanes night bowl thing, maybe just a switch to look for light blobs instead of dark blobs ;) An NFC system for tap to play should be a pretty straight forward proposition as well on open hardware. Have tags, tie their unalterable ID numbers back to a credit card/account and you are good to go. Start it with your regulars, league players if you have them, whatnot. You can also tie that back to league scoring. A few lanes at a time. I'm excited for you, this is a super fun project with endless sidequests.
