Frequently Asked Questions (FAQs)
How does a QR code work, and what is it used for?A QR code, short for Quick Response code, is a two-dimensional barcode developed in 1994 by a subsidiary of the Japanese company Denso Wave. It features a grid of black and white squares that can be scanned using a smartphone camera or a QR code scanner. Scanning a QR code allows users to instantly access information or perform actions like opening a website, downloading an app, or saving contact details. Thanks to their simplicity, versatility, and capacity to store more data than traditional barcodes, QR codes have become widely used across industries, including marketing, advertising, transportation, and healthcare.
Is it allowed to use QR codes created with this tool for commercial purposes?Yes, QR codes generated with this tool can be used for commercial purposes. You are free to incorporate them into products, advertisements, business cards, or any other commercial applications without restrictions. QRCode provides this service at no cost and places no limitations on how the generated codes are used. However, it is your responsibility to ensure compliance with any applicable laws and regulations related to QR code usage in your country or region.
Will the generated QR codes ever expire?No, the QR codes generated with QRCode are static and do not expire. Once created, they will function indefinitely as long as the linked content remains accessible.
Is there a maximum number of times a QR code can be scanned?A QR code can be scanned an unlimited number of times. It will continue to function as long as the linked content remains accessible.
Does QRCode collect or store my data?No, your data is not saved or reused. QRCode temporarily stores your QR code image files on their server for 24 hours to improve performance. After 24 hours, the image will be automatically deleted from the server.
Why isn't my vCard QR code displaying the correct fields?Not all QR code scanners adhere to the official vCard standard, which can cause contact fields to display incorrectly. We recommend trying a different QR code scanner app for more accurate results. Alternatively, you can generate the vCard QR code using another tool.
What should I do if my QR code isn't working?There are several reasons why a QR code might not work correctly. Start by checking for any typos or errors in the data. QR codes with large amounts of data, such as vCard codes, may need to be simplified for scanner apps to read them properly. Removing logos and ensuring sufficient contrast between the background and foreground of the QR code can also improve scanning.
