I was working on a business promotion project for a client and I showed her QR codes to put on her brochure to promote her yoga business and she was impressed. She did not know the QR codes could be so easily generated and applied. Now people who see her brochure or see her ad in a magazine only have to scan the QR code with a QR reader in their smart phone and they go directly to her site.
