In my last project post, I detailed how I set out to help my local coffee shop to adapt to the new way of digital, contactless menus during the pandemic. A custom Flask web server with a webpage displaying the coffee shop’s menu, set on a port to allow access external of the coffee shop’s network with a link embedded in a QR code is the bulk of the solution for them, but there was a little more that they needed.
Like many coffee shops, a single batch of pastries are made and delivered to the shop for the day. This means that as the day progresses, certain menu items are not available as they sell out. So while customers can access the menu digitally, their choice may be sold out. To remedy this, the addition of a webcam to capture a current image of the pastry case and display it alongside the menu needed to be added to the project.
