Unveiling the Magic Behind QR and Bar Code Technology: Decoding the Language of Images
Introduction: In the era of digitization, the seamless exchange of information has become an integral part of our daily lives. QR (Quick Response) codes and Bar codes are two technological marvels that have revolutionized the way we store and share data. In this blog, we will unravel the secrets behind these matrix-like patterns, exploring how they work, what information they contain, and how they interact with our cameras. Understanding QR and Bar Codes: Both QR codes and Bar codes serve the purpose of encoding information in a visual form, but they differ in their structure and functionality. Bar Codes: Bar codes are the older siblings of QR codes, having been around since the 1970s. They consist of a series of black lines and white spaces of varying widths, with each combination representing a specific set of data. The scanner reads these lines and spaces, converting them into alphanumeric characters that correspond to the encoded information. QR Codes: QR codes, on the other hand,
