QR codes make it easy for people to point-and-tap to access an online menu, connect to Wi-Fi or link to a social media site.

QR codes let people access information with a smartphone; instead of typing a URL, you point your camera at a QR code and tap. The QR code offers a link to all sorts of information and actions, including web pages, presentations, Wi-Fi access codes, business information (hours, locations) and social media sites. On an iPhone, Apple's camera app includes QR code 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 search.
The use of QR codes as a way 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 QR codes.
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 to web pages and other information.

How to create QR codes with Chrome
Google's Chrome browser includes the ability to obtain a QR code for web pages (Figure A).

Create a QR code link to web resources in the Chrome and Chrome OS browser.
The feature is built into the Share system in Chrome on both Android and iOS. However, you may need to enable the QR code feature in Chrome on desktop and Chrome OS systems.
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.
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 for later use.

If you consistently post on social media sites, a QR code can make it easy for people to access your social media accounts. 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.

Social media apps, such as Twitter, often include access to a QR code for your account within the mobile apps.
