Yes. The word QR Code (QR = Quick Reponse) itself is a registered trademark of Denso Wave Incorporated but QR Codes are free to use.
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.
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.
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?
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.
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.
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.
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.
If you create a QR Code qrd°by 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:
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
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
or as rasterized
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:
Yes. All QR Codes can be downloaded in a scaleable vector format as
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:https://blog.qrd.by/2013/03/15/qr-code-error-correction/
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.
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.
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.
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?
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:
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.
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:
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.
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
Then select your csv file and choose the file type
and select the
; as a column separator.
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.
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
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.
