What kind of information can be stored on QR codes?

Various types of information can be stored on QR codes. In a QR code creator, 23 types of QR code solutions are available, each requiring different data types to create. These include URLs, personal information, PDF files, marketing materials, product details, photos, videos, and many more data types. The choice of which QR code to create depends on the kind of information you want to encode, and accordingly, the appropriate solution type is selected. The relevant information corresponding to that solution type is then embedded within the QR code.
