- Qr codes are similiar to bar codes, except qr codes are in the form of a randomized image rather then randomized numbers .
- Product sellers often use qr codes to list special offers on their products or to give a secret message about something.
- Qr codes started off in Japan and eventually came to be used by U.S bussiness.
- Invented by the company Denso Wave.
- Qr codes help the small bussiness becuase they don't have to put all the print on a product when they can just use these little images that can be decoded for information that was printed into this generated code.
- This could save companies a lot of money by saving all the ink that would be used instead of these randomized images.
