QR codes, originally created in the 1990s for tracking car parts, saw a resurgence during the COVID-19 pandemic due to the demand for contactless technology. They are now commonly used for various tasks like ordering food, accessing Wi-Fi, and verifying identity. A phone camera can read QR codes, which hold up to 3KB of data, often in the form of links or contact information. While convenient, they also pose security risks due to potential scams that may redirect users to fake websites.
