if they don't need to pay for the terminal, that's a huge boost. currently restaurants use outdated and refurbished technology a lot of the times, so this should have a competitive advantage.
After installation, my question is, will support and maintenance for such hardware and software be still free?
I would say they will need to pay for maintenance themselves. Also are there limited number of free terminals for each restaurant or they will get as many as they need in the beginning?
The answers before from the dev sounds like they get no limitation on hardware, but I could imagen that they will check before if some restaurants need really a high amount of this if they order.
