Free QR Code Generator

A QR code is a two-dimensional barcode that, when scanned by a smartphone or QR code scanner, opens online content such as websites, contact info, and files. QR codes can also support advanced functionalities like payments, location sharing, event RSVPs, and multimedia, making them useful for marketing, events, and product touchpoints.

The father of the QR code is Masahiro Hara, an engineer at Denso Wave, who invented the QR code in 1994 in Japan. The QR code was created to overcome barcode limits, especially in automotive manufacturing, by storing more data and scanning quickly. Denso Wave holds the patent but chose not to enforce it, so the QR code is free to use.

A QR code is a two-dimensional matrix that stores data both horizontally and vertically, so it can hold more information and scan from many angles. A barcode is one-dimensional and stores data only horizontally, which limits capacity and usually needs more precise alignment for scanning.

QR codes are popular because they give instant, contactless access to digital content in seconds. You’ll see them on restaurant menus, event check-ins, and COVID-19 vaccination passes. In marketing, QR codes also drive engagement through creative placements, such as Taylor Swift’s giant QR code in Chicago.
