A QR code is a type of two-dimensional barcode that stores information in a grid of black and white square patterns. Compared to traditional barcodes, it can hold significantly more data and supports a wide range of characters including kanji. QR codes can be read from any direction (omnidirectional) and incorporate error-correction capability so they remain readable even when partially damaged.
