We offer a solution to register work hours on a project easily, smoothly, inexpensively and above all correctly via barcode scanning.
On your project you can print a 'project sheet' with barcodes for the different hour types.

The recorded time can then be neatly read in (via an locally installed program) for post-calculation.

Pocket scanners are used less these days given that most employees do, after all, have a smartphone in their pocket.
As an alternative, time and material can also be recorded via that IAMD Field app.
