QR codes are an easy and inexpensive way to use in the identification process. QR codes can be generated for free in the address http://www.qr-koodit.fi/generaattori. Just print the QR code with a sticker printer and attach it wherever you want. The size of the sticker can be quite small. A sticker that is the size of a finger tip is enough.
When you create QR codes, use the project's or employee's ID code depending on which needs to be identified.
