## QR Code

A Quick Response Code (or QR Code for short) is a machine readable tag that stores information like an ID, a URL, or other information.

A user is someone who uses GNU Health. A user record has at least a user name and a password. A user belongs to a company and can be linked to one or more employees who are logging into the system with that user. Access rights of a user are defined by assigning the user to one or more user groups. The language of the GNU Health user interface is defined on the user level as well. See Access Management.
