Have you seen small, black and white squares printed on posters or in magazines and newspapers? Have you seen any "designer" ones? They are called QR (Quick Response) codes and they can give travelers information quickly and easily. Tip: You must have a QR Reader on your smart phone and everything in the “tech world” must line up correctly. QR codes are not typically found on a website, but scan this one and read a message from Aladdin Travel. SS
From one of our readers: "On an Android phone, the "Google Goggles" app can read these."
