Yes. If you are an Administrator in Halaxy, you can set other users in your organisation (such as bookkeepers or administrative staff) to be able to see patient information without being able to see patient names.
To hide patient names for a user (NOTE: only Administrators are able to do this):
Click Settings > Users.
Click the Edit (pencil) icon next to the user's name.
Tick the "Hide Access To Patient Names" checkbox.
The user will now see anonymised names (such as "HK 123456") instead of actual patient names.
