What is a QR Code?
A QR (Quick Response) code is a two-dimensional barcode that can be easily scanned by smartphone cameras. It can store significantly more data than a standard barcode, such as URLs, plain text, Wi-Fi network credentials, or contact information.
Common Use Cases
- Linking physical flyers or menus to a digital website.
- Sharing a Wi-Fi password quickly with guests.
- Creating vCards so people can scan and save your contact info.
Frequently Asked Questions
Do these QR codes expire?
No. The QR codes generated here are static, meaning the data is encoded directly into the image pattern. As long as the destination URL remains active, the code will work forever.
Is there a limit to how much text I can encode?
Yes, standard QR codes have a maximum capacity. If you input too much text, the code will become too dense and difficult for phone cameras to scan.
