QR codes are two-dimensional barcodes that store data in a series of 0s and 1s, represented by black and white modules arranged in a square grid. The structure of a QR code consists of several components, including the finder pattern, timing pattern, alignment pattern, data modules, and error correction code. The finder pattern, located in the top left, top right, and bottom left corners of the QR code, helps the scanner detect the code's orientation and position. The timing pattern, consisting of alternating black and white modules, runs horizontally and vertically through the center of the code, allowing the scanner to determine the code's size and orientation. The alignment pattern, located in the center of the code, helps the scanner to accurately position the code and correct for any distortions. The data modules, which make up the majority of the QR code, store the actual data, such as text, URLs, or other information. The error correction code, which is calculated based on the data modules, allows the scanner to detect and correct errors that may occur during the scanning process. QR codes use a variety of encoding modes to store different types of data, including numeric, alphanumeric, binary, and Kanji modes. The choice of encoding mode depends on the type of data being stored and the desired level of error correction. QR codes can store up to 7,089 characters of text, 4,296 alphanumeric characters, or 2,953 binary bytes, depending on the encoding mode and error correction level used. The data storage capacity of a QR code is determined by the number of data modules, which is in turn determined by the size of the code. Larger QR codes can store more data, but may be more difficult to scan accurately.
