Unknown Encoding in QR Codes: How to fix it?

how to fix Unknown Encoding in QR Codes

Hey marketers, have you ever been thrilled to launch a new campaign featuring QR codes, only to find out that some people are experiencing issues when scanning them? Let's get into it!

QR codes are the go-to for anything from linking to your latest product to verifying transactions. However, what happens when these handy little codes run into issues with "unknown encoding"? Today, we'll explore why understanding encoding matters and what you can do to avoid or fix these issues.

What is QR Code Encoding?

For starters, let's talk about what encoding means in the realm of QR codes. In the simplest terms, encoding is the method used to convert information into a format that the QR code can understand. You've probably heard of the usual suspects like UTF-8 and ASCII, among others.

Why Encoding Matters

So why should you, the marketer, care about encoding? Well, the integrity of the data within the QR code relies on it. Imagine sending out a coupon code via a QR code and finding out it leads to an error page. Not a good look, right?

The implications of this could range from minor hiccups in a marketing campaign to more serious issues like the failure of financial transactions or, for healthcare marketers, inaccurate medical records.

Symptoms of Unknown Encoding

When you scan a QR code with unknown encoding, typically, your scanning app might show an error message. You could end up seeing something like "Unable to decode" or even worse, random gibberish that makes no sense.

Common Reasons for Unknown Encoding in QR Codes

💡
So why does this happen? Here is the common reasons.

Outdated Scanning Software: If your customers are using an older scanning app, it might not recognize newer encoding schemes.

  1. Regional Encoding Variations: Different regions sometimes have unique encoding standards that are not universally recognized.
  2. Custom or Proprietary Encoding: Some companies use custom encoding for internal purposes, which general scanning apps may not recognize.
  3. Data Corruption: Poorly printed or damaged QR codes can also lead to unreadable encoding.

How to Identify Unknown Encodings

There are online tools and software solutions that can help you identify the encoding of a QR code. However, these are not always 100% accurate.

Solutions for Unknown Encoding in QR Codes

  1. Use a Different Scanner App: If the scanner app is not able to decode the QR code due to an unsupported encoding standard or character, try using a different scanner app. There are many scanner apps available for both Android and iOS devices, and some of them may support the encoding standard or character that the original app does not support.
  2. Check Encoding Standard: If you are creating a QR code, make sure to use an encoding standard that is supported by most scanner apps, such as UTF-8. Avoid using non-standard encoding standards, as they may not be supported by some scanner apps.
  3. Avoid Non-Standard Characters: If possible, avoid using non-standard characters in the QR code. Stick to standard characters that are supported by most scanner apps.
  4. Check QR Code Quality: If the QR code is damaged, try printing a new one or using a higher-quality printing method. Make sure the QR code is not too small or too large, as it may affect the scanning process.
  5. Be Careful When Scanning QR Codes: QR codes can be used for phishing attacks, and scanning an unknown QR code can be risky. Always be cautious when scanning QR codes, especially if they are from an untrusted source. Avoid scanning QR codes that look suspicious or contain non-standard characters.

In conclusion, "Unknown Encoding" is a common issue that can occur when scanning QR codes. The possible causes of this issue are encoding errors, non-standard characters, and damaged QR codes. To solve this issue, try using a different scanner app, check the encoding standard, avoid non-standard characters, check QR code quality, and be careful when scanning QR codes. By following these tips, you can ensure that QR codes work as expected and avoid any potential risks.

Encoding standards are ever-evolving. Expect to see more universal encoding formats as we move forward, which should help alleviate some of these issues.

Understanding the implications of QR code encoding is crucial for the success of your marketing campaigns. Make sure to test multiple scanning apps and stay updated on encoding standards. As the adage goes, "An ounce of prevention is worth a pound of cure."
