QR codes have become an integral part of our daily lives in 2024.
However, their origins can be traced back 30 years ago to 1994 in Japanese Toyota factories.
The predecessor of QR codes, barcodes, were limited to letters and numbers, while QR codes can store a variety of information, including links and text.
QR codes function as physical links in the world, encoding complex data into a small package that can be easily scanned by devices.
The “QR” in QR codes stands for quick response, pointing to their ability to quickly redirect users to updated content.
Despite their convenience, QR codes also pose risks, as malicious individuals can create fake codes to steal personal information.
Users should exercise caution when scanning QR codes, treating them like any other online link and verifying their authenticity.
