Open and login the POS
You can open the POS application by double-click on the Store Commerce application on the desktop.
The application will open and ask to login with Username and Password, which is your Personnel Number and at first login password is 123.
After first login the system will ask to modify the password, so that you can choose yourself (so pick something that only you can know and always remember).
If there is no open shift for your login, the system will ask to open a new one, choose the first option in most cases.
