QR Code: A Digital Gateway
QR codes, or Quick Response codes, are two-dimensional barcodes that store information both vertically and horizontally, allowing them to hold a significant amount of data compared to traditional barcodes. Originally designed in 1994 for tracking parts in automotive manufacturing, QR codes have evolved to become versatile tools in digital communication. They can encode various types of data, such as text, URLs, or other data that smartphones can read and process. An example scenario illustrating their use is a restaurant menu. Instead of physical menus, restaurants display a QR code on the table. Customers scan the code with their smartphone to view the menu online, reducing physical contact and printing costs.
