A QR code is a two-dimensional barcode that stores information in a scannable square pattern. It helps people jump from a physical object or printed surface into a digital action with one scan.
QR stands for "Quick Response." Unlike a traditional one-dimensional barcode, a QR code stores data both horizontally and vertically. That gives it more capacity and makes it useful for websites, text, contact details, WiFi credentials, app links, and more.
Web pages, product pages, videos, forms, and download links.
vCard information such as name, number, and email address.
Instructions, notes, short messages, and reference details.
Phone calls, SMS drafts, WiFi login data, app installs, and more.
A static QR code contains the final content directly or points to a fixed destination. A dynamic QR code points to a redirect that can be updated later. Static is simpler; dynamic is more flexible for campaigns and content changes.
