Umbrella Pendant / Sharing Umbrella

Public umbrella-sharing projects have been deployed in several cities. But sharing economy does not guarantee less consumption on resources. In fact, vandalism and encroachment happen massively in existing umbrella-sharing projects.
Umbrella Pendant is a mobile device attached on personal umbrella.
It is designed to let the owner share his/her umbrella with others in need in short distance. After helping others, the owner will get payed as thanks-giving via the APP when the QR code is scanned.
