“Best QR Code Generator Tools for Linux In 2025”

One kind of two-dimensional barcode that may hold text, URLs, contact details, and other kinds of data is called a QR code or Quick Response code. Denso Wave, a Toyota subsidiary, created QR code in 1994 to follow car parts as they were being manufactured.

Because QR codes can store data both horizontally and vertically, they can hold a lot more information than regular barcodes, which only store data in one dimension (horizontally). Black and white squares placed in a grid make up a QR code’s design. These days QR codes have become a quick and easy way to share information like Wi-Fi credentials, contacts, texts and payment details. Payment QR codes are mostly used in cafes and mart.
