Frequently asked questions

To put it simply, a QR code is the natural evolution of the barcode. Its name comes from "Quick Response Code", and it is called that because it can be read very quickly. The code allows easy access to all kinds of information through your phone.

They are as useful as the types of content they can hold. In fact, in recent years this kind of code has grown in popularity among audiences. It makes sense: with a single scan you can access a wide range of information and even make certain tasks easier, like connecting to a WiFi network. A QR code can help you improve the service or product you offer, interact with your customers and promote your business, among other things.

At QRzen.io you can create 26 types. 8 are static and carry the content inside the code itself: website, text, WiFi, vCard, email, SMS, call and WhatsApp. The other 18 are dynamic and can be changed after printing: from a link or a PDF to complete pages, such as a menu in several languages, a business card, a coupon, an image gallery, videos, apps or a feedback form.

Several factors influence whether a person or potential customer reads a QR code, but the most important one is that whoever wants to scan the code has a phone. Today many phones can read QR codes with their own camera; just point at the code to scan it. If that does not work you may need to download an app made to read QR codes. But don't worry! There are several apps that do this.

The biggest difference between the two is that a dynamic QR code can be edited even after being printed, while a static one cannot. So a dynamic QR code lets us change both the function and the content at any time and as often as we want.

Another major difference is that dynamic QRs allow you to collect scan statistics to get as much information as possible.

No, due to the technical difference between each type of code.

QR codes also have an error-correction system. Thanks to it, up to 30% of the QR code structure can be damaged without affecting its reading. If the damage is greater, reading may fail.

There are different platforms and tools to create your own QR, but none like QRzen.io. With QRzen.io you can not only generate custom QR codes, you can also manage and edit your codes, and track them analytically.

Yes. On the home page you can create and design the most common QR types without an account. To download it you sign up, with your email or with Google, GitHub or LinkedIn, and that starts your free 7-day trial.

No. To avoid errors when reading the QR code, this option is not available. But don't worry, we use a standard size so the logo reads well and does not compromise scanning.

Yes. You can change the content of a dynamic QR whenever you want, even after printing it, without reprinting anything. A static QR carries its content inside the image: if you change it, the code is a different one and has to be printed again.

Yes. We recommend always scanning the QR preview with your phone to check that it works.

If you are in the trial period or subscribed to any of our plans, your active QR codes should work without issues.

If your QR codes don't work, it is most likely due to design elements. Some reader apps and phone cameras have trouble scanning complex QR codes.

Below are some design elements to keep in mind:

- Make sure there is significant contrast between the foreground and the background of the QR code.
- Make sure the QR code size is suitable for the scanning distance (in general, dynamic QR codes should not be smaller than 2 x 2 cm and static QR codes should not be smaller than 3 x 3 cm).
- Make sure the logo, if you use one, does not obstruct important parts of the QR code.

You can download your QRs in PNG, SVG, JPG or WebP, in sizes up to 4096 pixels, one at a time or several at once in a ZIP file. SVG is a vector format: the best choice for large-format printing.

Once you have downloaded your QR code in the desired format, you can print it from your computer. Always make sure to test your QR before printing to avoid any issues.

Yes, to dynamic QRs. You can protect them with a password, choose between which dates they work, give them a schedule by day of the week (for example, only when your venue is open) or set a maximum number of scans. Outside of that, whoever scans sees a notice that the code is not available.

For each dynamic QR you can see how many times it has been scanned and visited, how many unique visitors it has had, from which countries and cities, with which devices, systems, browsers and languages, and at what hours and days there is most activity. We do not embed third-party trackers: the data is yours alone.

A scan is someone pointing their camera at your code: it is the figure that tells you whether your poster works. A visit is any arrival at the content, whether by scanning or by opening the link you share from your dashboard. Every scan also counts as a visit, so visits are always the total and scans a part of it: if someone reads your QR twice that is 2 scans and 2 visits, and if they also forward the link and someone else opens it, 2 scans and 3 visits.

If you only share the printed code, the two figures will be nearly identical, and that is normal: nobody has arrived through the link. Neither visits nor the previews WhatsApp or Facebook fetch when sharing use up your scan limit.

No. All plans include unlimited QRs and scans, and so does the free trial. If you do not subscribe when the trial ends, the account is cancelled and your dynamic QRs stop working.

Yes. You can invite other people to your account and give each one a role, from managing the team to view-only access, and you all work on the same codes.

No. Neither your codes nor the pages people see when they scan them carry advertising or our brand: they are yours, with your content and your colors.

Yes. When you sign up you get 7 days with every feature, free and without entering any card. Since no payment method is saved, nothing is charged automatically when the trial ends: you only pay if you decide to subscribe.

Your account becomes read-only: you can sign in and see your codes, but not create, edit or download them, and your dynamic QRs stop working. Static ones keep working, because their content is inside them. If you subscribe, everything works again right away, with the same codes. If you do not subscribe, the account is deleted 30 days after you signed up, and we notify you by email beforehand.

3 plans with every feature: quarterly, biannual and annual. Only the duration changes and, with it, the monthly price. You also get a free 7-day trial to get to know the platform.

No, we do not make extra charges beyond the plan price + VAT. However, your credit card provider may charge a small transaction fee. For more information, contact your bank or card provider directly.

The moment the payment is made you can start using all of QRzen.io's tools.

It depends on the plan you subscribed to. We offer the following plans: quarterly, biannual and annual.

Yes, from your account, at any time.

From your account, in your billing details.

All your invoices are available in your account. If you need help, write to us.

Yes. Your subscription renews automatically at the end of each period, unless you cancel it before the renewal date. If you forget, you can request a refund of the renewal within 14 days of the charge.

Yes. You have 14 days from any charge, the first purchase or a renewal, to request a full refund, without having to explain why. Just write to us.

From your account, at any time and in a couple of clicks. The subscription stays active until the end of the period you have already paid for.

If you cancel your subscription, your dynamic QR codes will stop being active at the end of the contracted period. Static QR codes will keep working, since their content is fixed and does not depend on the subscription.
