Tools without an overview
Who has the hammer drill right now? Is the ladder still on site, or back in the warehouse? Without central management, unclear ownership and unnecessary time spent searching build up quickly.
Manage tools centrally
With Kernas, every tool gets its own asset number and a QR label. Scanning it instantly pulls up the stored information: current assignment, stored location, and the next inspection due date.
A typical workflow
Capture the tool → attach a QR label → assign it to an employee → on return: log its condition → keep inspection deadlines in view.
Identify by QR code
A scan shows a tool's current assignment and stored location — no need to ask around the team.
Check tools out and back in
Tools can be assigned to employees and later checked back in. Handovers can be documented with a signature and a condition note. That keeps it traceable who took a tool, what condition it was returned in — and who used it before that.
Inspections, documented
Many tools and machines may be subject to recurring inspections or maintenance. Kernas helps manage the relevant obligations and intervals, and document completed inspections in a traceable way.
Tool management instead of spreadsheets
A simple list is often enough for a handful of tools. With several employees or job sites, it quickly becomes unclear where a tool is stored and who it's assigned to. Kernas brings tool data, assignments, QR codes and inspections together in one central application. Existing Excel or CSV lists can be imported directly.
