If you have a company with more than 1 employee, you will probably have to share some tools, cars, trailers, cabins and other small things. When there are many tools and many employees, it is easy to get confused in the system about who took what and who did not return it because he had given it to someone else.
Shared tools keep track of it for you. Full overview of who took what, and when. You can create multiple tool warehouses in the company, so you can keep track of whether the tool is going back to the facility on the heath, or whether it is going into the office after use.
You can print QR codes that you stick on the tool, so that it is easy for the employees to say that they have taken it with them.
If the tool should go astray and a kind soul scans the QR code, he will get information about who owns the tool, and can call you. Even if he does not have the app installed!
