Coastal Frequency puts NFC posters at train stations. You tap your phone on a poster to get beach info and check in. Each tap tracks which beaches you've visited. Once you've checked in at all the beaches on the list, you get a free gift poster to keep. It's a fun way to explore new seaside spots while using the train. The project turns ordinary trips into a little adventure and gives you a nice souvenir to remember your journey by.
