frequently asked questions

What is a two-dimensional code?

A QR code, or QR code, is a two-dimensional barcode first created in 1994 by a subsidiary of Japanese company Denso Wave. QR codes consist of black and white squares arranged on a grid and can be scanned with a smartphone camera or a dedicated QR code scanner. When you scan a QR code, it can be used to quickly access information or perform actions, such as opening a website, downloading an app, or adding a contact to your phone. QR codes are becoming increasingly popular due to their ease of use, versatility, and ability to store more information than traditional barcodes. They are used in a variety of industries, from marketing and advertising to transportation and healthcare.

Can I use the QR code generated by this tool for commercial purposes?

Yes, you can use the QR codes generated by this tool for commercial purposes. This means you can use QR codes on products, advertisements, business cards or any other business application without any restrictions. QRCode provides its services free of charge and there are no restrictions on the use of the generated QR codes. However, you are responsible for complying with any relevant laws and regulations in your country or region regarding the use of QR codes.

Will the generated QR code expire?

No, QR codes created using QRCode are very stable and can be used indefinitely. This means that once a QR code is generated, it will continue to be valid as long as the content it links to is still available.

Is there a limit to the number of QR code scans?

There is no limit to the number of QR code scans. The QR code will run as many times as necessary as long as the content it links to is still available.

Will QRCode save my data?

No, your data is not saved or reused in any way. QRCode only caches your QR code image files on its servers for 24 hours to improve performance. This means that after 24 hours, the QR code image will be deleted from its servers.

Why doesn't my vCard QR code display the correct fields?

Not all QR code scanners follow the official vCard standard, which may result in mixed contact fields. It is recommended to try other QR code scanning applications for better results. Alternatively, you can try using another tool to generate vCard QR codes.

What if my QR code doesn't work?

There are many reasons why QR codes may not work properly. First, check the entered data to make sure there are no typos or mistakes. Sometimes, QR codes that contain large amounts of data (such as vCard codes) may need to be reduced so that a scanner application can read them correctly. Removing the logo and ensuring there is enough contrast between the background and foreground of the QR code will also help. For more information on why QR codes don't work, see this article.

Does QRCode work in all browsers?

QRCode requires a modern browser that supports HTML5, and officially supports Chrome, Firefox, Safari, Edge, and Internet Explorer 11. If you are using an older browser or a browser that is not officially supported, you may have problems using QRCode.
