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.

The free QR generator feature is built into the Share system in Chrome on both Android and iOS, and is also available in every desktop version of Chrome.

Note: Different versions of Chrome provide different QR code displays. Currently, Chrome on Android and desktop versions display the QR code with a dinosaur in the middle, while Chrome on iOS provides a standard QR code that lacks the dinosaur logo.

In Chrome on Android, browse as usual to a web page, tap the three-dot menu | Share… | QR Code, then optionally tap Download to save the code to your system for later use (Figure B).

On Android, tap the three-dot menu, Share, then QR Code to generate a code for a page.

In Chrome on iOS, similarly browse as normal to a web page, tap the Share symbol, then scroll down a bit in the displayed options and tap Create A QR Code (Figure C). On iOS, you’ll need to then tap Share | Save Image (or, alternatively, Save To Files) to preserve the code to scan and use later.

While you can create a QR code that links to a public web page for any of your social media accounts with the above apps, some social media services build access to QR codes right into their apps. For example, LinkedIn and Twitter both provide QR codes within their iOS and Android apps, respectively (Figure H). You might post this QR code along with the site’s logo on signage.
