Today, barcodes are an integral part of various industries, from retail to healthcare, logistics, and beyond.
Anatomy of a Barcode
The structure of a barcode is more complex than it appears. Barcodes consist of a series of parallel lines and spaces of varying widths, representing numerical or alphanumeric data. Each barcode is designed to be read by a scanner that translates the patterns into information a computer can process.
Typically, a barcode is divided into several sections: the start and stop patterns, the quiet zone, the data characters, and the check digit. The start and stop patterns signal the scanner to begin and end reading the barcode. The quiet zone, a margin of space before and after the barcode, ensures that the scanner can accurately detect the start and stop patterns.
The data characters in a barcode encode the product's information, such as its manufacturer, product type, and unique identifier. The check digit is a calculated number that verifies the accuracy of the scanned data, minimizing the risk of errors during the reading process.
