This review gives an elaborate understanding of the OnePlus Nord QR scanner: features, performance, use-cases, and troubleshooting tips.
Part 1: Introduction on QR Code Technology
1.1 What is a QR Code?
A QR code (Quick Response code) is a two-dimensional barcode to arrange information in a matrix of black and white squares. The QR codes, invented in 1994 at Denso Wave, can store different sorts of data such as URLs, contact details, etc.
Structure: QR codes are modules arranged in squares that encode data differently by different arrangements of dark and light squares.
Error Correction: It uses error correction so that recovery is possible even when the code is damaged or obscured.
1.2 Uses of QR Codes
The functions and uses of a QR code are vast and diverse from sector to sector.
Marketing and advertising: QR codes are present in advertisement and packaging through which consumers can be directed to websites, special offers, or product information.
Payment systems: These QR codes allow contactless payment by linking to financial accounts or payment applications.
Event management: A ticket and access pass would be QR coded for fast checking in and access control at events.
Personal Use: Users might save their contact information, Wi-Fi credentials, and any related personal data on QR codes for easy sharing.
