[Mark Jenkins] Impressed with the Covid 19 vaccination verification system that restaurants in Manitoba must use. Customers must present a QR code, which must be verified through a mobile application provided by Apple or Google.With the help of the local hackerspace, he came up with a bash script solution Only kilobytes are required, while the mobile application requires 50 MB. [Mark] Dissatisfied with the exclusivity of application usability and the lack of open APIs. His worries are not entirely theoretical-Google mysteriously withdrew their apps from the Play Store for more than a week.
The temporary result shown in the video below is a demo system called Alexandra. It consists of a receipt printer, a webcam used as a QR scanner, and a 2005 laptop running the script.This is just a proof of concept because [Mark] Specify clearly. There is still some work to be done-for example, the method used to authenticate to the Google server is temporary.But in the end [Mark] Hope to have a free software alternative as soon as possible, suitable for restaurant owners to use in their premises.
