In today's our digital age, Quick Response (QR) codes have emerged as an indispensable tool, seamlessly integrating into our daily lives. These square-shaped pixelated patterns of black squares on a white background might seem simple, but they hold a wealth of information and functionality, ranging from secure transactions to convenient data sharing.
What is a QR Code?
A Quick Response (QR) code is a two-dimensional barcode that stores information in a visually readable pattern. Initially created in 1994 by a Japanese automotive company, QR codes gained widespread adoption due to their ability to store more data than traditional barcodes and their quick readability. The distinctive square design allows for faster scanning and decoding compared to linear barcodes.
