QR code that you scan with ur phone and it brings up the dono page or paypal page would be useful imo but just clicking a link or a button ingame to open the browser is so much easier.
personally i wouldnt bother scanning QR codes for info, id probably go with a little question mark next to each item that you either click or hover over for more info about the item
I grew up as one of six kids and without practically any info on any goods ROFL, and we all grew up healthy without any quirks so many pple nowadays have.
If you say so bro
