I'm guessing this is a USA-based website made by someone in the USA? The tell is that the website does not offer any information about the market it serves, or intends to serves, and most Americans don't realise there's a global audience on the internet.
Maybe add something that says "Australians, this isn't for you."
Hello joshuawithers. Thanks for giving me a chance to respond. If an australian owns a home in the U.S. they are a potential customer. Or if they live in Peru and want to buy a home in the US, they are a potential customer. You are correct that we only offer it in the United States. Thanks for your comment. Richard
put up a form to ask for the name of the station, and get the browser to share the gps location. also ask for which lines stop here and where they are going.
submit all that to openstreetmap.
then do a search on the station name and gps location and display some useful information.
for the scavenger hunt, save the station codes in local storage in the browser, so that visitors can track their progress but you don't track visitor movements. only upload highscores to the server.
also display a random family friendly joke to encourage scanning.
experiment, see if you can find something that makes this go viral...
to get traction, look for groups that like to play scavenger hunts. also contact the openstreetmap community and public transport enthusiasts. you should find some people interested in doing something with this.
In the few hours I've been tracking, zero people have accessed a URL other than the root domain - which I'm guessing no NFC tags link to, and the local bus stop page I'm guessing is all from the blog post, seeing as though no other pages have been opened, I'm guessing my local bus stop isn't the busiest bus stop in the network.
I think this will be even more amusing if the net effect is zero actual visits from real bus stop scans. Shades of picturesofpeoplescanningqrcodes.tumblr.com.
