Simply input the information you wish to encode, customize your QR code if desired, and the generator will create one for you to download.
Once you have your QR code, you can print it on business cards, flyers, or any other promotional materials. This can be a useful way of sharing links to your website, social media profiles, or other forms of contact information without requiring someone to type out the details manually.
Do QR Codes Expire?
QR codes themselves do not expire, as they are simply a visual representation of encoded information. However, the content that a QR code links to, like a URL or a specific resource, can expire or become inactive over time. For instance, if you create a QR code that directs to a web page and that page is later removed or the URL changes, the code will no longer lead users to the intended content.
To ensure your QR code remains functional, it’s advisable to regularly check the links associated with your codes. If you anticipate that a link will change or become inactive, consider creating a new QR code that directs to a stable, long-term destination, such as a social media page or your main website.
