Where do I get help and support?

If you subscribe to a Premium or White Label membership, you get up to one hour assistance and support. We are happy to answer questions about the platform. Support services do not include implementation work nor creating mobile websites or QR Codes from our side.

Contact Us

You can also give us feedback or request new features in our feature database and you will find more resources and How-To's on our Blog.

How can I be sure that in the free account, my QR codes will remain working forever, for free?

Our free service is offered on an as-is basis, see our terms of service. We currently have more than 50000 satisfied users on a rock solid platform. Users are always welcome to test our premium solutions, however qrd.by will never charge to the users for the free solution. Our service was launched in 2011, so we have survived the start-up phase and our teething troubles. Today we are a profitable business with organic growth.

How many QR codes can I manage in my account?

You can find the exact number of QR codes per account in our price list.

The number corresponds to the maximum total number of QR codes that you can manage and change from your account after registration.

The number does not refer to QR codes per month or QR codes per year - the number of available QR codes remains the same for the entire life time of your account. You can upgrade to a different plan at any time or contact us for an individual offer if you need more than 500 QR codes.

I created a QR code from another company. Can I activate and edit the QR code via your service?

It will depend on the URL encoded in the QR Code. You can easily find out by scanning it and looking at the destination URL from your QR Code scanner.

  • Your provider URL is encoded. If you have created a QR code in a paid account with a competitor, you must first activate the account with the provider and the code will work again.
    You can then redirect the QR Codes to our platform if you wish. This will involve having both accounts active.

  • Your own domain/subdomain is encoded. If it was created using your own domain, you can easily recreate them using our White Label QR Code Manager
    We also offer a paid white label solution that makes your QR Codes independent of us. You can switch to another provider at any time and move your existing QR codes.

If you want to use QR codes in the future, we offer a free version.
Please refer to our product page

Can I downgrade from my existing plan to another?

It depends. If you have a

Paid plan (Starter, Premium or White Label) > Free plan
No. The domain in the QR Code changes when upgrading and you cannot go back to your free plan.

Premium > Starter
Yes. Please contact our support team and we will take care of the changes.

White Label > Paid plans (Starter or Premium)
Yes. However, it is only possible if you have only 1 user under the White Label plan and you are not using a custom domain. Please contact our support team and we will take care of the changes.

Notes:

  • The next invoice will reflect the conditions of your new plan
  • Partial refunds cannot be offered when downgrading
  • You cannot have more QR Codes or Landing Pages than the ones on the new plan before downgrading

Will a free QR code be deleted if I also signed up for a paid plan?

QR codes created in a free account have no expiration date.

QR codes created in a paid account will be deactivated if you do not subscribe to a paid plan.

It is not possible to transfer QR codes from a paid account to a free account.

QR Codes

Are QR Codes for free?

Yes, the term QR Code (QR = Quick Response) itself is a registered trademark of Denso Wave Incorporated, but the use of QR codes is free.

The QR Codes that you create on our website can be used free of charge and commercially and you can create as many static QR codes as you want.

You can learn more about the history of QR Codes here: https://www.qrcode.com/en/history

What is the minimum size of a QR Code?

A QR code with a length of up to 72 characters (this is the length of a typical URL) should be printed in a size of 2 x 2 cm when scanned from a distance of 20 cm. Theoretically, smaller sizes of 1 x 1 cm are possible on modern smartphones with a camera that supports autofocus. Learn more in our post Minimum Size of a QR Code.

Do my QR Codes expire?

No.

Static QR Codes never expire since the target URL is encoded in the QR Code and you will be redirected to the URL directly.

Dynamic QR Codes in your free account will never expire, except you will delete the QR Code yourself or the target URL is redirecting you to an expired website. Our broken link checker will always keep you informed if your QR Codes are working.

After the evaluation period on one of our paid subscription plans, your account will be deactivated and therefore your QR Codes will stop working if you do not subscribe. However, once subscribed your QR Codes will not expire if you have been a customer for at least one year and if you have no pending invoices.

Is a QR Code still readable when some areas of the QR Code are damaged?

When creating a QR Code, a certain level of error correction can be specified so that the code stays readable, even if the QR Code is partially damaged or hidden. There are 4 different levels:

  • Level L - up to 7%
  • Level M - up to 15%
  • Level Q - bis 25%
  • Level H - up to 30% may be damaged

The higher the error correction, the more the QR code can be damaged, but the bigger is the size of the QR Code. Learn more about this topic in our post QR Code error correction.

Please find a detailed tutorial how to print QR Codes here Printing Guide for QR Codes.

What is a static QR Code?

A static QR Code has the target URL directly encoded and will never expire. However, there are some crucial disadvantages when using static QR codes:

  • You cannot track who scanned the QR Code but more important:
  • You cannot change the target URL once you have printed the QR Code! So, if the target URL is broken or not reachable the QR Code will not work anymore. Therefore, we strongly recommend you use dynamic QR Codes.

Learn more about the difference between a static and dynamic QR Code.

How do I create a designer QR Code?

To create a Designer QR Code follow those steps:

  1. Click on one of your QR Codes and choose Custom QR Code
  2. Choose the colours for the QR Code
  3. Choose a design pattern
  4. Set an optional logo inside the QR Code
  5. Put a frame around the QR Code
  6. Set a call-to-action
  7. Download the QR Code

Read our full Epic QR Code Designer Guide for detailed instructions and tipps.

Why is my designer QR Code not readable?

Caution should be exercised with Designer QR Codes. If the QR code has too many design elements, it will no longer work. For example, if the squares in the QR code are converted into circles and a logo is also placed in the QR code, the QR Code might not be readable anymore.

Possible Reasons

There are a number of reasons why a QR code cannot be read

  • You are using an old smartphone with a poor camera resolution
  • The QR Code Reader app has a bad algorithm to decrypt the QR Codes
  • Some QR code Readers cannot decode a white QR code on a black background
  • The logo in the QR code is too big
  • The colors have too little contrast with the background
  • Instead of squares, design elements such as round or polygon symbols are used in the QR code

Solutions

Should there be reading problems with a QR code

  • reduce the design elements
  • remove or resize the logo
  • make sure that the colors of the individual elements have enough contrast with the background color

The safest variant that a QR code can be read by all readers, is the Standard QR Code . or the Transparent QR Code .

The less complex the QR Code, the easier it is to decrypt it. Designer QR codes are more difficult to decode, so the scan position, the angle of the camera to the QR code and how far the camera is from the QR code matters. How well a QR code can be read also varies from app to app and algorithm to algorithm.

Test, Test, Test

At each design step, test whether the QR code is still readable and only after then add a new design element.

Also note that not all QR code readers can decode the Designer QR code equally well. Basically, you should always test with a smartphone with a poor camera and apps with weak decoding algorithms. If the designer QR code can still be read, you are on the safe side.

Is there a possibility to include a video (e.g. from YouTube) or a mp4 file in a QR Code?

Yes, you can! Simple redirect to a video URL in a QR Code and a user can watch the video on his mobile phone right after scanning the QR Code. The video must be hosted on a third party platform (e.g. Vimeo, YouTube). We do not host videos ourselves.

My QR Code does not work anymore. Please help!

First check if your QR Code is static or dynamic

Get a QR Code Reader and scan your QR Code. Make sure that you have a QR Code App that displays the URL before redirecting you to the website. If the URL starts with https://qrd.by/... it is a dynamic QR Code anything else would be a static QR Code or you have created the QR Code with another service, which, if that is the case, we cannot help. More details to find out what URL is stored in your QR Code can be found in the post Decoding QR Codes

Static QR Codes

If you have created a static QR Code and the QR Code is redirecting to a URL that does not exist anymore, you have to restore the target URL, otherwise the QR Code will not work anymore. We strongly recommend you to use dynamic QR Codes in the future.

Dynamic QR Code

If you have created a dynamic QR Code, the good news is that you can change the target URL without printing your QR Code again. To do so please log into your account. If you forgot your password or you cannot login, please read our Your Account FAQs



Update the target URL of an existing QR Code

Please check first if your target URL, that the QR Code is redirecting to, exists. If the target URL is not available (anymore), the QR Code is working, but the website behind has to be restored. If the website is not available anymore you can change the target URL of the dynamic QR Code to a webpage that exists as shown in the following screenshot.

Edit an URL of a dynamic QR Code

Re-Create a deleted QR Code

If you have deleted the dynamic QR Code in your account, just create a new QR Code with the same custom shortened URL. To do so enter the target URL first and then click on "Optional Settings" and set the same custom shortened URL as shown in the following screenshot.

Set custom shortened URL

How do I restore a deleted QR Code?

If you have deleted a QR Code you can either recreate it using the same short URL or you can go to your log section. You can go to you log from your account settings and click on Restore.

  • Please nothe that this will restore only the QR Codes and the target URL. Old scan statistics will not be restored since they were deleted.
  • You cannot restore advanced QR Codes (App, PDF, Multilanguage, Geofenced, etc.) and landing pages. In that case you have to recreate it using the same short URL.

If you did not print out your QR Code yet, just create a new one with your previous target URL. If your QR Code is already public, please decode the QR Code and create a new QR Code with that same Vanity URL.

How do I clear all or delete specific test scans so that they don't mess up the statistics?

If you want to delete your test scans you have two options.

Reset all scans

Click on options next to the QR Code and click on Reset. This will reset all tracking data at once.

reset qr code

Delete specific scans

You can also delete specific scans. Go to the statistics of your QR Code and scroll to the bottom. In the list of scans click on the trash icon to delete a specific scan.

delete qr code scans

Can I deactivate a QR Code?

We do not offer the option to deactivate a QR Code. You can always delete it, but you have to take into account that if a user scans a printed code it will return an error message.

A best practice would be do one of the following options:

  • Change destination URL - You can change the destination URL of a QR Code any time (Options > Edit URL)
  • Change destination URL and create a custom landing page - You can create a custom landing page to inform the user why the QR Code is not longer valid and redirect the it to this page.
  • Use scheduling function - If you know in advance when a QR Code has to redirect to a different URL you can plan ahead of time using the Schedule function (Options > Schedule)

Help! My QR Code has been hijacked! How is this possible?

If you create a dynamic QR Code on our platform nobody can change the target URL except you or anyone who has access to your account. We do use SSL for secure communication so it is very unlikely some intercepts your session. There is a much higher chance that the website of where your QR Code leads to has been compromised.

What is an offline QR Code?

An offline QR Code is a QR Code where all information is encoded in the code itself and no Internet connection is necessary. One big disadvantage of offline QR Codes is that once they are printed their content cannot be changed in comparison to dynamic QR Codes. Read more about offline QR Codes.

Can I change the URL in my QR Code?

If you created a dynamic QR Code you can change the target URL anytime. The QR Code stays the same and you don't have to print the QR Code again. Read more about dynamic QR Codes.

How do I create a one-time scan QR Code?

With scheduled QR Codes you are able to create one-time scanable QR Codes the redirect the user to a specific URL only for one time. Read the following tutorial how this works.

How to create one-time scanable QR Codes

How does a shortened (=custom or vanity) URL in a QR Code work?

If you create a QR Code you can shorten the URL, so less characters must be encoded in the QR Code. Thus the QR Codes is smaller in size and you need less space when you print the QR Code. The shortened URL in the QR Code is also called a custom URL or vanity URL.

Please note, that you can not change the shortened URL after creation. You will need to create a new QR Code with a different shortened URL.

To give you an example of a regular URL versus a shortened URL:

The very moving farewell speech at Stanford University by Steve Jobs in 2005 can be found at:

I have already created and printed my QR Code. Can I change the URL of my QR Code?

Yes, in a dynamic QR Code you can change the destination URL at any time. Static QR Codes have the destination address is permanently entered and the URL can not be changed after creation. Learn more about a static versus a dynamic QR Code.

I created a QR code in the past to use in print media. How do I decode the URL of the QR Code and how do I find out if it is dynamic or static QR Code?

Get a QR Code Reader and scan the QR Code. Make sure that you have a QR Code App that displays the URL before redirecting you to the website. If the URL starts with "http://qrd.by/..." it is a dynamic QR Code anything else would be a static QR Code. Read more about:

Decoding QR Codes

Yes, you can directly upload your logo in the vectorized .eps format or as rasterized .png, .jpg or .gif file. After merging the QR Code with your logo the branded QR Code can be printed in a perfect quality and any size. Please also test the branded QR Code, by scanning it from different apps and devices before going into production. Read more under:

I have two QR Codes with the same URL encoded, but they look different. Why?

Every QR Code Generator uses different algorithms and also different encodings (Numeric, Alphanumeric, Byte Mode, Kanji Mode, ECI Mode) when creating a QR Code. Therefore, it is possible that different looking QR Codes can have the same text information encoded. Another possibility are different error correction levels (L, M, Q or H). The higher the error correction is set the bigger the QR Code gets. Learn more about here:

//help/article/qr-code-error-correction

What QR Code Scanner do you recommend?

I created a Facebook QR Code, but it does not redirect me to the Facebook page. Why?

Read our latest blog post on how to Deep Link QR Code in Facebook

Use QR Code Reader with deep linking

If you scan a QR code and the internal browser of the QR Code Reader App is called, the internal browser may not be able to switch to the Facebook app. Try to scan the QR Code with our reference QR Code Reader App.

Check Facebook URL

The other possibility is that you have entered a wrong Facebook URL when you created the Facebook QR Code.
Check if the URL really redirects to your Facebook page.

Update Facebook App

Your current version of your Facebook App does not support mobile deep linking. You can find this out by scanning the following reference QR Code, you should be redirected to the Facebook Fan Page of qrd.by directly. If this is not the case, your Facebook App does not support deep linking.

facebook qr code qrd.by

Are you referencing to a Facebook Group?

If you want to link to a Facebook Group you need the Facebook Group ID first.

You can find the Group ID it the Source Code of the Group Page. For example go to this group page and press CTRL - u to access the source code. Then search for fb://group/ and you will find a fragment like this where you can copy the Group ID:

<meta property="al:android:url" content="fb://group/691611197690284" />

Now you can use the following URL to create a Facebook QR Code that automagically redirects the user to your group in the Facebook App when installed:

https://www.facebook.com/groups/691611197690284
