  • Does it scan from my desired distance where I place it (in cases of printing your QR codes on billboards?) 
  • Does it lead to the correct information you have input?
  • Does it work when scanned with different devices?

How to scan the QR code

How to test a QR code online 

Once you have generated your QR code using a QR code generator online, don’t hastily download and print thousand of them right away. Do QR codes test first. 

Here’s what you should do:

1. Scan the QR Code in various lighting levelsqr code test online

The first thing to consider if this is- what is your target? 

Do you want to get the most scans in daytime or night time or even both?! 

Lighting is very inconsistent all throughout the day, so it would be advisable to do a QR code test or scan in different lighting levels. 

Low, medium, light, and bright light. 

If you have determined your time of day in which you would want your QR code to get most scans, and it doesn’t work, you can also adjust the contrast of your QR code color. 

Just make sure the background color of your QR code is lighter than its foreground. 

The next thing you can do after this displays your QR code in the desired area and try to do an actual QR code test. 

If your QR code doesn’t scan or doesn’t work, you can increase the code’s color contrast. 

2. Do a QR code test on different devices. 

Sometimes, a QR code works in an Android phone but fails to scan in iPhone, or it could work in both. Sometimes even QR code readers and social media apps that can scan QR codes do not work. 

The best for you to do is scan the QR code using various devices and see if it functions. 

3. Test the distance of the QR code it will be scannedqr code test sheet

First things first. What is the purpose of your QR code, and what is your target outcome for this campaign?

The QR code can either be scanned from a short distance or from a long-distance or even both depending on your purpose and target.  

If you plan on printing your QR code in a product packaging, business card, or in your wine bottles, there’s no need for you to make them scan from a long distance as this will only require to be scanned from a shorter distance.    

However, if you are planning to do a public display of your QR code, for example, your printing a QR code on your billboard, you need to consider the distance the QR code will be scanned from and consider the size of your QR code. 

You might opt for a bigger size if you are planning to have your QR codes displayed on billboards or any advertising environment that will require your QR code to be scanned from a distance.

4. Test internet access in that area.

Many public areas provide an internet access spot, so it would be advisable to place your QR code with Wi-Fi service in the nearby area. 

However, if your QR code solution is in static form, it will be scanned right away, even without internet access. 

Best practices when generating your QR code for it to have a better scan
