The Trolley Buddy System is a mesh network enabled solution to reduce neglect of shopping trolleys within the community. Leveraging existing rituals with physical coin locks, the Trolley Buddy replaces this with the use of a payment card to deposit a virtual $2 to unlock a trolley. The Trolley Buddy features an E-paper display for energy efficiency and to reduce the digital nature of the product compared to alternatives. In addition to the Trolley Buddy, the Bay Buddy is attached to a trolley bay, to sense when a trolley is placed in a designated area further reducing neglect.
