QR Code Analysis

Abstract: Two-dimensional matrix barcodes called "Quick Response" (QR) are used. It must store much information compared to one-dimensional barcodes, and it must be decrypted quickly using any handheld device, including a smartphone. When creating two-dimensional matrix codes, these two considerations are taken into account. The possibility of security becomes a significant factor when a bar code contains sensitive information or private data Users are unsure of whether a QR code will connect them to reliable information or a malicious website because QR codes are simply square bar codes with a distinctive design. Recently, QR codes have been used in numerous application fields, and their use is growing quickly. As a result, more individuals are becoming acclimated to this technology and using it properly. Due to the QR code's increasing popularity as more people use smartphones, it is swiftly acquiring universal acceptance. Given their broad acceptance, the security aspect of QR codes, such as data leakage and data tampering, is critical. The paper offers a comprehensive overview of QR codes and their applications.
