What Is A QR Code?

According to Wikipedia a QR code is a type of matrix barcode invented in 1994 by the Japanese automotive company Denso Wave. A barcode is a machine-readable optical label that can contain information about the item to which it is attached.

According to Techtarget a QR code (quick response code) is a type of two dimensional (2D) bar code that is used to provide easy access to online information through the digital camera on a smartphone or tablet. A barcode reader in the camera interprets the bar code, which typically contains a link to view a webpage, send an SMS text message or call a phone number. The technology for QR codes was developed by Densa-Wave, a Toyota subsidiary. The codes were originally used for tracking inventory and required a separate reader app, but beginning with iOS 11 and Android 8.0, readers are native to most mobile device cameras.
