QR codes themselves do not inherently collect your personal information or data. They are simply a tool for encoding information, such as URLs, which can be scanned by smartphones to quickly access web content. However, the websites or apps you visit via QR codes may collect data, so it’s essential to be cautious and understand privacy policies.
How Do QR Codes Work?
QR codes, short for Quick Response codes, are two-dimensional barcodes that store data in a machine-readable format. When scanned with a smartphone camera, they can direct users to websites, display text, or perform other actions like adding a contact or sending an email. The QR code itself is just a medium for information delivery and does not have the capability to collect or store data.
