To all developers here is a request of 1 or 2 products that i believe, in the peak of the pandemic, could sell a lot, due to sanitary reasons:
A system for restaurants that costumers can access the restaurant o bar menu thru a qr code on the table, a qr code that link to a responsive webpage where they can see the menu from that specific establishment, there are already a few platforms in market and are selling like water on desert, like for instance: bonee.net or mastertaag.com.
This system could be sold as 2 versions, one with a panel for multiple restaurants an the other for single restaurant.
No mobile APP, just backend and frontend.
Developers, think about it!!
