UPCAkoodi

UPCAkoodi, commonly known as UPC-A (Universal Product Code Add-on), is a barcode symbology used primarily for retail product identification and inventory management. It is a variation of the Universal Product Code (UPC), which is widely adopted in North America for tracking trade items in stores.

The UPC-A barcode consists of twelve numerical digits, typically encoded as a series of black and white bars. The code includes a 6-digit manufacturer identification number, a 5-digit product number, and a single check digit used for error detection. In addition to the primary 12-digit code, UPC-A can be supplemented with a 2 or 5-digit add-on code, known as UPC-A add-on, which provides additional information such as book edition or magazine issue.

The barcode is widely supported by barcode scanners and point-of-sale systems due to its simplicity and reliability. It is designed to be easily scanned in various retail environments, facilitating quick checkout processes. The encoding scheme of UPC-A utilizes a combination of guard bars and digit patterns to ensure accuracy during scanning.

UPC-A is governed by standards set by organizations such as GS1 (Global Standards One), which ensures global interoperability. This barcode symbology is an essential component of retail and supply chain logistics, helping streamline inventory, sales tracking, and checkout operations efficiently.

In summary, UPC-A barcodes are a vital tool in modern retail, providing a standardized, reliable method for identifying and tracking products throughout the supply chain.
