DFW released a competitive request for proposals (RFP) for Smart Restroom Technology in 2019. The requested scope was to initially provide pricing for over 8 different features and sensor types including throughput counting, stall occupancy, staff monitoring, passenger digital signage, connected dispensers, connected plumbing, and a smart restroom platform to manage staff and analyze data. DFW shortlisted TRAX Analytics (formerly a part of Infax, Inc.) in which they requested a pilot to be run at one pair of restrooms during the evaluation period.

TRAX Analytics was selected as the finalist and was requested to install the system in 163 restrooms airport-wide during the height of the COVID Pandemic. The airport selected throughput counters, staff monitoring with beacons, the TRAX mobile app, stall occupancy, digital signage, and connected dispensers as their final scope.
