metroKEY is an interactive access control system, delivering end to end visibility on how the organics drop off facility is being used, with a user interface that actively encourages participation with fast sign up, easy to follow instructions, map locations of units, and clear information on what can be deposited. metroKEY enables users to create their own metroKEY account following a standard 2-step verification and password set up using their smartphone Once logged in to the metroKEY app, access to the unit can be granted once the one time ‘tick box’ user agreement condition has been met. This feature means that Admin intervention is not required to grant user access at the time, though within the metroKEY web portal, your admin staff are able to both grant and revoke user access as necessary. Making recycling as easy as trash disposal demands streamlined processes that enable access to the organics unit. Once users have signed in, the metroKEY app opens the unit latch via an illustrated pop-up question banner with a simple yes/no tick box for access once the user is within Bluetooth range of the unit. Where fill sensors are deployed smartphone app users can also see when a bin is full, allowing them to navigate to the nearest available drop-off location.
