In an era dominated by smartphones and digital connectivity, Quick Response (QR) codes have become an integral part of our daily lives. Originally created in 1994 by a Japanese automotive company, Denso Wave, QR codes have evolved from their industrial roots to find a myriad of applications across various industries. From marketing and advertising to contactless payments and event ticketing, QR codes have seamlessly integrated into our world, offering a convenient bridge between the physical and digital realms.
