QR codes have become an integral part of our digital landscape. Whether you're scanning to access a restaurant menu, make a payment
What is a QR Code?
A QR code (Quick Response code) is a type of matrix barcode that can hold a wide range of data. Unlike traditional barcodes that store information linearly, QR codes store data both horizontally and vertically, enabling them to contain more complex information like URLs, vCards, geo-locations, and even payment data.
History of QR Codes
The QR code was developed in 1994 by Denso Wave, a Japanese automotive company. Originally created for tracking automotive parts during manufacturing, QR codes have since evolved into a widely used digital tool for various industries. The rise of smartphone technology has drastically accelerated the adoption of QR code scanning worldwide.
Types of QR Codes
- Static QR Code: Once generated, the content of a static QR code cannot be changed. Perfect for permanent information.
- Dynamic QR Code: Allows you to change the linked data even after the QR code is printed or shared. Ideal for marketing campaigns.
