Bar codes and Radio Frequency Identification (RFID) systems are critical technologies in supply chain systems because they:

Data Acquisition: Enable the timely and accurate capture of data related to inventory, shipments, and other supply chain activities.

Tracking: Provide real-time visibility into the location and status of items within the supply chain.

Efficiency: Reduce manual data entry errors and streamline processes such as receiving, inventory management, and order fulfillment.

Tracking truck locations on cross-country deliveries (A) is typically done using GPS technology. Providing paperless invoicing of goods (C) and producing schedule broadcasts for suppliers (D) are not primary functions of bar codes and RFID systems.
