QR codes are matrix barcodes that can be read by smartphones and stored various data like text and URLs. They have more data capacity than traditional barcodes. Users need a smartphone with a camera and QR code reader software to scan and interpret QR codes. Examples of how libraries can use QR codes include providing hours, branch locations, call numbers, tours and art descriptions. There are several free online generators that can be used to create QR codes.
