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.

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

The QR Codes you create on our side can be used free of charge and commercially. When you register a free account, you can manage up to 1 QR Codes in your account. If you need a larger volume of QR codes, look at our product overview page.

No. Once you have created a QR Code in your free account 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.

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.

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

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.

This really depends where you want to print the QR Code on. Please read more about the Minimum Size of a QR Code.

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.

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

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 to decode a QR Code
• How to create a QR Code with a Vanity URL

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)

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.

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

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:

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.

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:

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:

Please click on the options next to the QR Code and then on Design QR.

Now click on the right transparent QR Code icon.

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

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:

For iPhones you don't need a QR Code Scanner. Since version iOS11 you can scan a QR Code with the native camera app. For all other phones we recommend the QR Code Scanner from i-Nigma. Learn more about here

Just make a screenshot of the QR Code and decode the QR Code with one of the following Apps:

• neoreader.com (iOS, Android, Amazon)
• qrbot.net (iOS, Android)

Here is an example how to make a screenshot with an iOS device and how to decode the QR Code by just simply click on the image icon at the top and select the screenshot from the image library.

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

No.
The beauty of vector graphic is that you can make them as big as you want without blurring the QR Code, because only polygons are saved and not pixel by pixel. Therefore only very little memory is needed.

Yes.
The QR Code only contains the link to the .pdf file and not its content. So if the file is edited, nothing changes in the QR Code.

While creating the PDF QR Code, or clicking on "Options > Edit" for existing PDF QR Codes, you can add a cover image to the preview page instead of the default PDF thumbnail.

You can add a title, a description, a website and show/hide the sharing button.

You can also set a direct download of the PDF file without an intermediate page. It works well with Apple devices, since they can display the PDF file directly in the browser after scanning the QR code. This option is not recommended on Android devices, since a download usually takes place in the background and the PDF file is not immediately displayed.

Unique Visitors

Unique Visitors is the number of clearly identifiable devices that scanned the QR Code. The number is computed by summing up all unique IP addresses from the devices. The IP addresses are stored anonymously and a scan can never be directly linked with a person. Thus scans are anonymous and GDPR compliant.

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.

Note: If you scan a QR Code from different devices and they are all connected to the same Wifi-network, the number of unique visitors is 1 and will not increase.

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 three 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.
• We are looking up IP addresses to their countries with the database from https://www.maxmind.com. Even they claim there is a 99,8% accuracy on country level, there is a chance that the IP address is assigned to the wrong country and therefore will display you the wrong information.

The most accurate results you get, when you enable the GPS tracking function for QR Codes.

Another possibility that requests show up from a different country is that the URL might have been shared through Facebook, WhatsApp, WeChat or other social media platforms by the user or the app after scanning. You can have a look on the Referred section of the statistic page for more details.

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.

First and foremost, the IP address of the smartphone that scanned the QR code is used. This allows the country of origin to be determined with an accuracy of 99%.

For each IP address also a position is approximated. The accuracy can range from one to 1000 kilometers. On average the accuracy is about 200 kilometers. If you would like to determine a more precise position, activate the GPS location in the options menu of a QR code.

If the GPS tracking function is switched on for a trackable QR code, the position can be determined down to an accuracy of only a few meters. Read more about:

You can enable GPS tracking of QR Codes by clicking on the GPS icon in the options menu next to a QR Code.

Yes. Geo-targeted QR Codes redirect the user to a specific website depending from which country he is scanning the QR Code. This feature is available in the White Label QR Code Manager.

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.

You have three possibilities to create a QR Code with geo information:

• You can encode a position in the QR Code, that will show the location to the user after scanning the QR Code. This is called a GEO QR Code
• You can add an address to the QR Code, if you know where you want the place the QR Code e.g. at your door, at a bus station, at your office. Any time your QR Codes are scanned you can see on a map where and how often your QR Codes have been scanned. Create a geo-tagged QR Code
• If you print your QR Codes e.g. on flyers and you want to know where your QR Codes are scanned, you can enable the GPS tracking feature. People are asked to submit their location after scanning the QR Code. Learn more about QR Code GPS tracking

In general, a scan limitation only applies to a free account when using dynamic QR Codes. Static QR Codes have no limit at all. If you use a free account, we rely on a fair use policy of 100 scans per day. If this daily limit is exceeded once, you will receive an information e-mail from us, which notifies you that if the limit is exceeded again, the account and the QR Code will be blocked.

If the scan limit is exceeded a second time, you will receive an e-mail from us, that the QR Code has been temporarily deactivated and you can switch to a paid plan.

Subscribing to our Starter Plan with a one-time annual membership of USD 60, - will allow you unlimited scans and the QR Codes continues to work even when terminating your subscription.

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.

Yes. In the integrated scanner of your iPhone the preview only shows the top-level domain qr1.at without the subdomain.

If you want your own domain to be displayed, we recommend our white label product. There you can run our platform under your own domain e.g. qr.mycompany.com.

If you create a QR code and then scan it with an iPhone, the domain mycompany.com will be displayed in the preview instead of qrd.by.

More about this product and instructions on how to set it up Domain can be found at:

• White Label QR Code Manager
• Set up your domain

You can upgrade your current plan to the white label plan at any time in your account settings. Existing QR codes continue to work and newly created ones will contain the domain you have selected.

We only send one message per scan per second. You will receive a scan notification as often as the link in the QR Code of is scanned from a mobile device. Some QR Code Readers request the link twice, this explains the double notification.

We generally use QR codes with a secure URL encoded, for example https://qrd.by/test
If the QR code now redirects to an insecure website without an SSL certificate, Blackberry refuses to forward.
We strongly recommend that you secure your landing page with an SSL certificate. These are available free of charge at https://letsencrypt.org. This not only makes your website safe, it is also rewarded by Google and may appear in a better place in the search result.

Our service is free of any kind of advertising.

If a user is using a free QR Code reader, the reader app may display an advertising banner. We have nothing to do with this and unfortunately have no influence on it.

The good news is: almost all smartphones can already be used with the built-in camera app read the QR Code and make third-party applications obsolete. This means that neither we nor the smartphone will display advertising banners.

If you user our white label product, you can additionally use our service under your domain (e.g. qr.mycompany.com)

Learn more about our White Label QR Code Manager

In the media library you can upload pictures or pdf documents and link them directly with a QR Code.
You can also link your QR Code to a YouTube Video.

Call-2-action buttons may be placed on a landing page to offer a user a specific action that will be triggered when the button is pressed. An example is to show a "Call me" button on a digital business card that allows the user to initiate a call to the owner of the business. More use cases:

• Initiate a call
• Download a PDF
• Send an E-Mail
• Goto an Address
• Start a WhatsApp Chat

In the landing pages editor you have the option to hide your mobile business card from search engines who respect the noindex, nofollow meta tag.
When we see bots crawling a landing page, we do not display or output any e-mail 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.

When we send an e-mail we use a Sender Policy Framework (SPF) that your e-mail server can check, if the IP of the server that has sent our e-mail is allowed to do so. If not your e-mail-provider can block our e-mails.

Since we do use a correct SPF-record that matches all IP-addresses of the mail servers we send e-mails from, there is another possible reason why our e-mails are not delivered to your inbox:

The mails we send you, are forwarded to another e-mail address. Since the last e-mail server is seeing the IP address of the forwarding e-mail server and not the IP of our server, the receiving server refuses to deliver the email because the IP check for our SPF record fails.

There are 2 possibilities to overcome this issue:

• Use an e-mail address in your account that is not forwarding e-mails
• Disable the SPF-record check on the receiving e-mail-server for the domain cbscluster.com

When you send an e-mail to us and you get back an SPF error, you must check with your sysadmin.

This error happens due to anti-spam checks, if you don't have a correct SPF record in your mail domain.
You can type in your domain in the mxtoolbox and see, if it passes. If not, your sysadmin must fix the SPF record.

If you want to have more control over your QR Codes, you can subscribe to the White Label plan and use your own subdomain instead of qrd.by.

Here you will find free, fast and robust alternatives that will make scanning a better experience with no ads.
