The article discusses the modernization of strandkörbe (beach cabins) in Germany, which are now equipped with smart locks that can be opened using a mobile app. The Strandbutler company has developed this technology, which allows users to rent and access the cabins more conveniently and securely. The smart locks have a built-in NFC chip and a GPS function, which enables the cabin’s location to be tracked and ensures that it is in good condition. The article highlights the challenges of developing this technology for use in extreme coastal conditions, but the company has overcome these challenges and is now providing its service to 10,000 beach cabins across Germany. The article concludes that there is still room for growth in this niche market, as there are estimated to be 100,000 beach cabins in Germany alone, and the technology has not yet been adopted internationally.
