2. How Barcodes Work in the Supply Chain |
At its core, barcode technology provides a means of encoding information in a format that can be read automatically. This is particularly useful in supply chain management, where fast, accurate data collection is essential. There are two main types of barcodes commonly used in the supply chain: 1D barcodes and 2D barcodes. |
1D Barcodes: These are the traditional linear barcodes composed of parallel lines and spaces. A standard 1D barcode can encode up to 20-25 characters, usually representing product IDs, item numbers, or batch codes. These barcodes are widely used for product identification, inventory tracking, and order processing. |
2D Barcodes: These barcodes store information in both horizontal and vertical dimensions, allowing them to hold much more data than 1D barcodes. The most popular 2D barcode types include QR codes and Data Matrix codes. These can store much larger amounts of data, making them ideal for more complex tracking and additional product information, such as production details, expiration dates, and shipping routes. |
Once a barcode is printed on a product's packaging or label, it can be scanned by a barcode scanner or a mobile device equipped with scanning software. The scanner reads the pattern of bars and spaces, which is then converted into a numerical or alphanumeric code. This code is matched with the relevant information in a database, such as the product's location, batch number, and stock levels. |
