wow "14 other competitors in the umbrella-sharing industry" So how do the others do it? I could only imagine some simple number lock unlockable when you scan a QR and pay a deposite, but I don't know how return could work. Maybe it could be verified by someone else unlocking it from the same place you claimed to have left it? And if nobody ever unlocks it, because you just took it home, it flags you as a thief after 3 times? Or slightly snowbally: you pay 5 dollars to get an umbrella with a number lock and only get it back when someone else rents it again. This way you have to make sure to put it where it gets used. Ah, dedicated stations of course work, but take away some of the organic simple nature http://umbracity.com/ http://umbracity.com/ edit: one with number locks: (I wonder how the return works) https://www.shanghaiexpat.com/news/umbrella-sharing-comes-shanghai https://www.shanghaiexpat.com/news/umbrella-sharing-comes-sh...
