If you want to register to Kolibrie HRM you need to identify yourself with a legal identification document. It is not allowed to use your drivers license as an ID document. 

Are you not in the possession of an EU-identification document? Then use your residence permit. 

Take a picture of the front- and back of your ID document in the app. Not the front- and back of the passport cover. The app will show you how to do this.

Still problems with identifying? Please contact Kolibrie HRM.
