What is Barcode?
Turkish: Barkod
A barcode encodes product or asset information as bars and spaces so optical scanners can identify items quickly.
What is a Barcode?
A barcode is a visual identifier encoded so machines can quickly read physical items such as products, boxes, shelves, assets, or documents. The most common form is a 1D barcode made of bars and spaces; retail EAN or UPC codes are familiar examples.
How Does It Work?
A barcode scanner detects reflected light differences from the bars and converts the pattern into a numeric or alphanumeric code. The code usually does not contain the full product name; it acts as a key to a product record in a database. Code 128 is common in logistics, EAN-13 in retail, and internal codes in warehouse or production tracking.
Reliable scanning depends on print quality, label size, contrast, scanner type, and whether the code maps correctly to system data.
Business Use
Barcode systems support warehouse receiving, point-of-sale, shipping, returns, asset counting, and production-line tracking by reducing manual data entry. Inventory management systems use barcodes to record product movements faster. A QR code is two-dimensional and can carry URLs, text, or longer data.
A healthy barcode project is not only label printing; product master data, numbering rules, scanner choice, and ERP integration should be designed together.
