Abstract - The rise of modern technology has led to a surge in wirelessly based security applications. These applications often utilize various wireless communication technologies to build and implement security access control systems. Among these technologies, Quick Response (QR) codes have gained widespread use in contactless applications across sectors like access control, library book tracking, supply chains, and tollgate systems. This paper explores the integration of QR code technology with Arduino and Python to develop an automated QR code-based access management system. When a QR code is detected, the entry's QR scanner collects and compares the user's Unique Identifier (UID) with the system's stored UID. The results demonstrate that this system effectively grants or denies access to secure environments in a timely and reliable manner. Such security systems play a crucial role in safeguarding physical and intellectual property by preventing unauthorized access. While traditional door locks, including mechanical and electrical locks, address basic security needs, advanced systems like the one described here contribute to creating structured data files for authorized individuals, enhancing overall security measures.
