[Vo]:qr codes

My first QR code.  It was easy as pie.  COVID is making these touchless codes take off. http://www.angelfire.com/scifi2/zpt/temp/qr_code.png

[Vo]:QR codes

They are the little black squares on things.  I recently went to a restaurant that I could view a menu by scanning a QR code.  This was new to me.  Has anyone put a QR code on your buniness card, or other product?  What do you think of them?  I installed the Red Laser app to read these codes.  D
