Which of the following technologies best enables pulling products through the supply chain?

According to the APICS CSCP - Supply Chain Management Certification, a point-of-sale (POS) system is a technology that captures sales data at the time and place of purchase by scanning bar codes or RFID tags on products or using other methods of identification. A POS system can transmit sales data in real time to other systems in the supply chain, such as inventory management, demand planning, replenishment, or distribution. A POS system enables pulling products through the supply chain, as it triggers orders based on actual customer demand rather than forecasts or schedules.
