The Eco Digital Wallet turns recycling and sustainable activities into a digital currency to promote environmental-friendly practices and instill values of stewardship among city residents and visitors. Fostering environmental stewardship and sustainable practices have become more crucial as the consumption and spending of people is on the rise, necessitating the need to create impact on the urban environment. To encourage that, the Eco Digital Wallet can be installed on a smartphone and linked via NFC or barcode to the recycling kiosks. Cameras can also be used to log and track certain sustainable practices. The Eco Wallet is then topped up with tokens and digital currency in reward for those activities, which can be then used for rewards, services, and eventually hold real monetary value.
