The Unique Advantage of the RPi 4 in the hospitality environment: Mirrored displays #113
Description
The RPi 4 makes it 'easy as pie' to add a second display which mirrors the first touchscreen display and allows customers to watch the process of having their order entered by hospitality employees. This is not something which hospitality customers are typically allowed to view on proprietary point of sale systems. It can be done for well under $200, on displays as small as 12", or even on large TVs.
