What is the purpose of the QR code?

QR codes (Quick Response codes) are two-dimensional codes that can store more information than traditional barcodes, such as links, contact details, or payment information. They serve to quickly connect web resources with physical places or processes. Their purpose has expanded from their original use in the automotive industry for faster image reading and greater data storage capacity, to marketing, logistics, and payments, allowing for quick access to information without manual typing.
