Wellcome to QR Code and Barcode app

Ways to Use QR Codes - When you scan a QR code, it might open a link to a website or social media account, display a YouTube video, show a coupon, or contact details.

Advertising is probably the most common use of QR codes. Brands can add a QR code to a billboard or magazine QR Code For Video Star, for example, that sends users to its website or a coupon or landing page. For the user, this takes away the hassle of typing in a long URL, or jotting it down on paper. The advertiser benefits from real-time results in which the user immediately visits their website rather than waiting until they get home, or worse, forgetting about it altogether.

Another use is through a virtual store, in which there's a large touch screen in a public place, such as a subway station or plaza. Shoppers can scan items with their smartphones and get the items delivered at a chosen time and location. Each piece has a unique QR code and works with a mobile app that stores payment and shipping information.

QR codes are often used to transfer cryptocurrency, including Bitcoin. Some cemeteries around the world have started adding QR codes to tombstones to make it easier for visitors to locate the gravesite.
