A QR Code or Quick Response Code is a scannable barcode used to encode data such as text or an URL.
A QR code is a special barcode that can take a visitor directly to text, URL, or other data. QR codes require a special QR reader that is available for free on most phones. Though it is not common to post QR codes when advertising, utilizing a QR code somewhere in your advertising provides a convenient way for the consumer to get directly to what you want them to look at.
