Quick response (QR) code deformation
Examples of techniques for quick response (QR) code deformation are described herein. An aspect includes receiving a first QR code, wherein the first QR code is scannable by a QR code scanner at a first range of angles. Another aspect includes determining a scanner angle, the scanner angle being outside of the first range of angles. Another aspect includes generating a second QR code based on the first QR code and the scanner angle, wherein the second QR code comprises a deformed QR code that is scannable by the QR code scanner at a second range of angles that is distinct from the first range of angles.
