Scan equipment in and out

I’m looking at equipment management. Basically I want to pick up say a radio, scan it to check it in or check it out. Then apply that to an employee. The management template lets me pick a list of say radios. While this is nice, I am looking at a way to scan, click and go vice scrolling around to file one of 150 devices and assigning this to one of very many employees. How can i make this a scan to check in or check out to keep work flowing and streamline the process of checking gear in and out
