Each QR code can represent various types of information, including URLs, text, contact information, and more. Additionally, QR codes can be customized with different colors, designs, and error correction levels. With such flexibility and versatility, QR codes have become ubiquitous across a wide range of industries and applications, from marketing and advertising to logistics and ticketing.
