On windows side you’ll create a windows user called rdp1 (or whatever you like)
On SambaPOS side you’ll create a Terminal and a Menu that customized for your handheld device screen. You can Map this menu to Terminal on Ticket Type > Menu Mapping so you don’t need specific user on SambaPOS side.
Login to SambaPOS? The waiter who holds the terminal will use his own SambaPOS PIN code that he uses while logging in through PC. After running SambaPOS on tablet everything is same like running on PC.
If you are using Server PC as a POS terminal you’ll also need to switch to windows account based local settings. To be able to do this login to windows with rdp1 user. Start SambaPOS and go to Local Settings. Click Display App Path button and copy Settings.txt file to the User Path. You can display User Path by clicking Display User Path button. When you do that Local settings will start working by windows user account.
