QR reader
Square pattern decoder
A QR reader is software or a device that scans and decodes QR codes—those square black-and-white patterns that encode information like URLs, contact details, or payment links.
Most smartphones have QR readers built into their cameras: Just point your QR reader at the code to pull up the menu.
