How to create QR codes: 5 methods
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).
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).
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.
In Chrome on desktop systems and Chrome OS, you may need to enable the QR code option. To do this, type chrome://flags in the omnibox, then press Enter. Enter "QR code" in the search box that displays, and then adjust the setting to Enabled (Figure D). Restart, as prompted.
Once QR codes are enabled, when you click or tap in the omnibox, the QR code icon displays on the right side of the box, next to the bookmarking star. Select it to display a QR code for the page, and then select Download to save the image.
How to create QR codes with QRbot
QRbot lets you create codes that link to a web page, as well as codes that encourage other actions, such as adding a contact, connecting to Wi-Fi, sending an email or SMS or making a call (Figure E). Go to the QRbot QR Generator, select an action, add any necessary details, then download your code. The web-based version is free. The developer, TeaCapps, offers free Android and iOS apps, as well as upgraded pro options for both platforms (for $4.99 and $5.99, respectively) that remove ads and provide access to extra features. Additionally, the upgrade on iOS lets you adjust colors, add a custom logo and select from more themes.
How to create QR codes with Barcode Generator
In addition to the methods above, people who use Windows also might consider installing the free Barcode Generator app by Vevy Europe-S.P.A. from the Microsoft Store. As with Chrome and QRbot, Barcode Generator provides several pre-built action options to create QR codes for email, Twitter, Facebook, SMS, Wi-Fi, Flickr and YouTube, among others (Figure F). Select an action, enter your data, then save the generated image.
How to create QR codes with iQR codes
On macOS, iQR codes - QR Code Art Studio provides fast, fill-in-the-blank creation of QR codes for phone numbers, SMS, email, locations, web links, contact info, calendar events, Wi-Fi access and more (Figure G). This $14.99 app also lets you make more adjustments to the display of the QR code than any of the above options. These tweaks include pixel styles, corner and resolution sliders, foreground and background colors, as well as customizations of the corner control points. The app also provides a built-in tool that assesses the readability of your QR code along with tips to help ensure reliability.
How to access QR codes in social media apps
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.
