This key tracking system was designed and engineered from the ground up for BuildingLink.com. We had to design a unique identification key tag holder and the entire storage drawer with the intelligence to map and keep track of any activity in the drawer. Any key removal or any key usage is monitored. A sheet metal construction and aluminum extrusions were only part of the design, we had an injection molded key tags and custom design electronic circuitry and firmware developed for this project.
Definitely one of the most creative people I have worked with
