How to test QR codes

Few pieces of technology have had the kind of roller coaster ride in popularity that the QR code has.

QR codes initially became popular as high-speed internet and smartphones came on the scene, but they experienced a resurgence at the onset of the COVID-19 pandemic. In fact, they’ve experienced a sharp uptick in popularity — culminating in a 94 percent rise in the number of QR code interactions between 2018 and 2020.

Most consumers have seen QR codes at this point — they’ve been replacing paper and plastic menus at restaurants, providing product information at brick-and-mortar stores, or even adding extra interest to product packaging.

Smartphones have also now developed to automatically scan QR codes through native photo apps (as opposed to consumers needing to download a third-party QR code scanner), making the tech almost ubiquitous.

In your business, chances are you have a handful of potential ways to use QR codes across your physical workplace, emails, products, or services. But you should also make sure your QR codes work effectively. As you dive into implementing them, QR code tests help you create the most seamless customer experience possible.

How QR codes enhance your business

Thoughtful business owners have gotten increasingly creative in the ways they use QR codes. Here are a few examples:

Physical spaces

  • Product packaging to direct consumers to review information or read nutritional labels
  • Menu stands to direct diners to a restaurant menu
  • Coupons to activate discounts
  • Business cards to link to LinkedIn pages and profiles
  • Billboards to conveniently and instantly share business websites, surveys, and forms

Digital spaces

  • Online forms to link to outside URLs or additional product/service information
  • Payment links to provide a unique code to pay with apps such as Venmo, Apple Pay, and CashApp
  • Social media apps to visit and follow profiles on social media channels, such as Snapchat

How to run a QR code test

Ensuring users can easily access both the code and the information it leads to is key to creating a frictionless customer experience. That’s why, before you use a QR code, you need to confirm a few essential details during a QR code test. Here are the four central aspects of QR code testing.


Your QR code should stand out against a lighter or darker background. Make sure to test a QR code multiple times to see if it takes a lot of effort to get a smartphone to recognize it. If trouble persists, try increasing the contrast of the code itself on a lighter background or doing the reverse on darker backgrounds. Otherwise, consider moving the code to an area with better lighting.


QR codes can show up right in your face (with placards and business cards) or hundreds of feet away (like billboards and murals). Make sure your QR code tests reflect how far a user will likely be from the code so you can ensure it’s large enough to scan.


QR codes should work on a multitude of potential devices, not just your own. This includes the most recent models of the most popular Android and iOS devices. The cameras on these smartphones change with every iteration, so you want to make sure you’re not creating a prohibitive experience for someone who doesn’t have the iPhone 13.

Though many devices now incorporate QR scanners directly in the phone camera, keep in mind plenty of people still use older phones that require third-party apps to scan QR codes. Spend some time testing your code out on the top QR scanner apps to ensure a seamless experience.


Though this is less dependent on the QR code itself, you’ll waste your chance with potential customers and annoy established customers if the reception in the area with the QR code is too weak. If possible, make sure internet or data service is quick where you place the code. Otherwise, people won’t wait around to find out what’s on the other end.
