QR codes let people access information with a smartphone; instead of typing a URL, you point your smartphone camera at a QR barcode and tap to scan. The QR code offers a link to all sorts of information and actions, including web pages, presentations, Wi-Fi access codes, business cards and information (hours, locations) and social media sites. There are two different types of QR codes: Ones that link to one set location on the web (known as a static QR code) and one’s that send customers to an updatable web location (known as a dynamic QR code). On an iPhone, Apple’s camera app includes QR code scan support. On an Android device, both Google Assistant — with the words “scan QR code” — and the Google Camera app, with Google Lens mode, let you point your camera at a QR code then tap to scan and search.

The use of QR codes for marketing and to access online menus, especially, proliferated during COVID-19 efforts to minimize physical contact points. Many sales systems, such as Addmi, OpenTable, Shopify and Square, let business owners generate multiple QR codes for customers.

You don’t need a point of sales system to create QR codes. The following five methods offer reliable ways to create QR codes to provide contactless access and marketing to web pages and other information.
