QR Codes

Are QR Codes for free?

Yes. The word QR Code (QR = Quick Reponse) itself is a registered trademark of Denso Wave Incorporated but QR Codes are free to use.

Do my QR Codes expire?

No. Once you have created a QR Code it 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.

What is a static QR Code?

A static QR Code has the target URL directly encoded. You can not track who scanned the QR Code and you can not change the target URL once you have printed the QR Code. It will never expire unless the target URL is broken or not reachable. Learn more about the difference between a static and dynamic QR Code.

My QR Code does not work anymore. Please help!

Please check first if your target URL exists. If the URL, that the QR Code redirects to, is not available anymore, the QR Code is working, but the website behind has to be verified. To find out which URL is behind the QR Code read How to decode a QR Code

Did you delete the QR Code yourself? Then this will help you How do I restore a deleted QR Code?

How do I restore a deleted QR Code?

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.

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.

Why should I use a shortened URL in a QR Code?

If you create a QR Code can shorten the URL, so less characters have to be encoded in the QR Code. Thus, a smartphone is able easier to read the code, even if the code is printed in a size of less than 2 square centimeters. To give you an example:

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

QR Code with long URL

The smaller QR Code with the shortened URL looks like this:

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

In a static QR Code the target URL is hard coded and cannot be edited retrospectively! With a dynamic QR Code you can edit the target URL anytime. Please use this function to avoid situations like this:

We created QR codes for a number of YouTube videos that were then printed on a batch of brochures. Today one of our employees accidentally deleted the YouTube videos which means we now have a lot of brochures in circulation with non-working QR codes. Is there any way you can change the URLs for us so they link to different YouTube videos? It would save us a lot of trouble as we’re in the middle of critical campaign launch.

If you are using static QR Codes we cannot do anything in that case. But you can use our free QR Code Manager to create dynamic QR Codes here:

Create 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 "" it is a dynamic QR Code anything else would be a static QR Code. Read more about:

Decoding QR Codes

Can I brand my QR Code with my own logo?

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:

Embed a logo in a QR Code

I want to print a QR Code on a big poster. Do you have QR Codes in a high resolution?

Yes. All QR Codes can be downloaded in a scaleable vector format as .eps,.svg or .pdf image.

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. This is why 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:

I created a Facebook QR Code but it does not redirect me to the Facebook page. Instead I am redirected to my Facebook timeline. Why?

There are two possibilities. One is that your current version of your Facebook App does not support mobile deep linking. The other possibility is that you have entered a wrong Facebook URL when you created the Facebook QR Code. 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. Update your Facebook App to the latest version. Try your QR Code with other mobile phones and check if you experience the same behavior.

QR Code Tracking

What is the difference between Requests and Unique Visitors?

Unique Visitors

Unique Visitors is the number of clearly identifiable persons who scanned the QR Code. This size is computed from the IP address or a session cookie of the scanning device. Scans are anonymous, thus a scan can never be directly linked with a person.

Requests (Scans)

The number of requests indicates how often the QR Code has been scanned. A QR Code may be scanned 1 or more times by the same person. Therefore, the number of requests is always greater than or equal to the number of unique visitors.

Can I get the phone number, name or address of the person who scanned the QR Code?

For security reasons it is not possible to track the person's phone number or any other details like name or contacts from the address book just by scanning the QR Code.

However, you can build a form on your landing page to retrieve personal data of the person who scans the QR Code. See How to generate Leads?

If I look at the statistics I see scans and requests from countries where I did not publish the QR Code. How come?

We identify a QR Code scan by the device's IP address and the user agent sent by the device. There are two scenarios why a QR Code incorrectly shows up from a different country:

  • The device is behind a proxy (e.g. Blackberry devices are routing all their Internet traffic through the U.S.)
  • A bot from abroad is faking its user agent. Normally we filter out bot requests. However if a Bot is sending a regular user agent string (like an Apple iPhone does) we cannot distinguish between a real iPhone and the Bot.

How can I view how many visitors have scanned my QR Code?

Using the QR Code Manager lets you manage all your QR Codes at once and you can view scanning statistics including unique visitors, visiting countries, browsers and more.

I already have a QR Code. Can I integrate it in your system for tracking?

If you created a static QR Code, you can NOT integrate it in our system.

However, if you have a dynamic QR Code, you can integrate the code in our system by following the steps below:

  • Create a dynamic QR Code on qrd°by that redirects to the URL of your original QR Code.
  • Then redirect your original QR Code to the shortened URL of the newly created QR Code on qrd°by.

The result is a double redirect. If your original QR Code is scanned, the user will be redirect to the shortened URL of the QR Code in our system. There we will track where, when and from which device the QR Code has been scanned before we forward the user to the original URL.

When I export a .csv file of QR Code scanning statistics to Excel the file is broken up and not very usable.

The exported csv file uses a semicolon ; as a column separator. If your Excel uses a comma , as a default separator when opening a csv file, all data will show up in one column.

You can overcome this problem by opening Excel, go to the Data menu and click on From Text. Then select your csv file and choose the file type delimited and select the ; as a column separator.

What are the benefits of registering a free account?

As a registerd user you can view and manage all your QR Codes (up to 5) in one place. You can even create mobile websites like business cards and much more. See the feature list for more details.

What are the benefits of a premium account?

As a premium user you can create a much higher amount of QR Codes (up to 1000) and 1000 landing pages. Have a look at the feature list to compare the details.

What happens when I exceed my daily scan limits.

Scan limitations only exist for free accounts. We have a fair use policy for free accounts. But if your daily scans heavily exceed our recommended limit of 1000 scans per day, we block your account for security reasons. If this is this case please get in contact with us.

Mobile Business Card

I want to save my mobile business card as a vCard. This works on all devices except the iPhone. Why is that?

When you are requesting a vCard in an Iphone's Safari browser, the browser does not know what to do. Instead of opening the vCard directly in the browser, the vCard has to be sent as an email attachment to the mail client on the iPhone. The mail program of the iPhone allows importing a vCard directly to the phone's address book.

New: All iPhones with an OS > 6 can now store vCards directly from the Safari browser into the address book.

Please note the some QR Code Readers do not support to save vCards directly from the App. Here is a list of QR Code Readers we recommend:

QR Code Readers

When I try to save a business card on my phone I get the error message: "Frame load interrupted"

This message may occurs if you are scanning a QR Code of a mobile business card with the QR Code reader Quick Scan from iHandy Inc. The app cannot handle the mime type “text/vcard”. We already send the bug report to iHandy Inc. but did not get any response.

Please use another QR Code reader instead. Here is a list of QR Code Readers we recommend:

QR Code Readers

Are mobile landing pages crawl able by bots?

Landing pages in the premium version will not be indexed by search engines who respect the noindex, nofollow meta tag. Mobile business cards in the free version are public by default and may be crawled by bots. However, when we see bots crawling a landing page, we do not display or output any email address. Bots who do not respect meta tags or fake their user agents may index your landing pages if your pages are linked from any other public website. However, in the landing pages editor you have the option to hide your mobile business card from search engines.
