A couple of dumb questions regarding QR Codes.
Who makes them?
Can I advertise my web site/business on the QR code?
So if someone scanned it would my web site come up? - Could I put one on a magnet on the side of my truck. Or are the QR codes just for products?
Do I buy one or do poeple rent the codes, not sure how the whole QR code thing works.
Thank You in advance.
