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. There are two types of QR codes: One links to one set location on the web (known as a static QR code), and the otherone sends 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, 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.
We’ll look at various methods that 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 a free QR code generator for web pages (Figure A). The free QR generator feature is built into the Share system in Chrome on both Android and iOS and is 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.
Android
In Chrome on Android, browse as usual to a web page, then:
- Tap the three-dot menu.

In Chrome on iOS, browse as normal to a web page, then:

- Tap Share, then choose either Save Image or Save To Files to preserve the code to scan and use later.
Desktop
In desktop versions of Chrome on Windows, macOS or Chrome OS devices, right-click or tap with two fingers on a touchpad to display the Create QR Code option. The generated QR code displays in the upper-right area the browser. You may then scan the image or select the Download button to save it (FigureD).

More options: Create a QR code with Adobe, Canva and ChatGPT Plus
There are many other ways to create a QR code; here are three more.
Adobe
Adobe suggests that QR codes make it easy for people to access a “website, social media accounts, and other online resources.” With an Adobe account, you can use its free Adobe Express QR code generator, which offers a few style, color and file format options (Figure H).
Canva
The online design platform Canva provides a QR code generator in its web-based editor. With a free Canva account, you can create a QR code (Figure I) and customize the margin size, background color and foreground colors, then place the graphic as desired in your design.
ChatGPT
Even AI chatbots are entering the QR code-generation competition. Subscribers to ChatGPT Plus from Open AI, maker of the popular chatbot ChatGPT, can create a QR code with a prompt (Figure J). For example, try:
Create a QR code that links to https://techrepublic.com
The system responds and gives you a link to the QR code images you requested. Modify the above prompt as desired to create a QR code that connects to whatever public link you prefer.
How do you use QR codes?
The use of QR codes, especially for marketing and accessing online menus, proliferated during COVID-19 efforts to minimize physical contact points. Many sales systems, such as OpenTable, Shopify and Square, let business owners generate multiple QR codes for customers.
Do you use QR codes at your organization? If so, what types of information do you link to for your customers: menus, social media marketing, Wi-Fi sign-in)? What systems or apps do you use to create QR codes? Let me know how you use QR codes on X, formerly known as Twitter, at @awolber.
