2. The Evolution of Product Identification |
Product identification has evolved from simple manual tracking methods to more sophisticated automated systems. In the early days, product identification relied primarily on human intervention, using methods such as handwritten labels, paper-based invoices, and verbal communication between suppliers and retailers. While these methods were sufficient for smaller, localized operations, they quickly became inadequate as businesses scaled and global supply chains became more complex. |
The introduction of barcodes in the 1970s was a game-changer for product identification. GS1, a global standards organization, developed the Global Trade Item Number (GTIN), a unique identifier for trade items that could be encoded in barcodes and scanned quickly at various points in the supply chain. Barcodes greatly improved the efficiency and accuracy of product tracking, enabling retailers and manufacturers to automate inventory management, reduce human error, and streamline logistics operations. |
As technology continued to evolve, Radio Frequency Identification (RFID) emerged as another key innovation. RFID tags contain microchips that store product data and can be read by scanners using radio waves. Unlike barcodes, which require line-of-sight scanning, RFID tags can be read remotely, even from a distance or when the product is in a sealed package. This made RFID particularly useful for tracking products in real-time across large distribution networks and improving stock visibility. |
The growth of digital technologies such as cloud computing, blockchain, and the Internet of Things (IoT) has further revolutionized product identification. These technologies enable real-time tracking, end-to-end visibility, and secure data sharing among various stakeholders in the supply chain. |
