I’ll admit ignorance to the complexity involved, I had just thought that a sharpie would be less conspicuous than a bag full of QR code stickers if management were to search employees which I believe they do in amazon warehouses. Also the communicability of it, being able to tell others in different warehouses “fill in these squares on the QR code” rsther than distribution of stickers.
Thanks for the in depth reply about feasibility of it though, very interesting!
