What do most JIT systems rely on?

• A. Manual counting
• B. EPOS, barcodes and RFID
• C. Batch processing
• D. Excel spreadsheets

Answer: (B)

Just-In-Time systems rely on real-time, accurate information to trigger replenishment. They need a seamless flow of data from when a product is sold or moved to when stock is updated, so supplies arrive exactly when needed. Electronic point-of-sale systems capture sales data at the moment of purchase, and barcodes or RFID tags identify each item quickly and precisely. This combination provides up-to-date stock levels and movement, allowing the system to signal replenishment promptly and keep inventories lean. Other options don’t fit as well. Manual counting is slow and prone to human error, delaying decisions. Batch processing means larger, less flexible stock and slower responses, which undermines the pull-based nature of JIT. Excel spreadsheets might help with data organization but aren’t the live tracking infrastructure that automates and speeds up stock updates. So the best answer is the integration of EPOS, barcodes, and RFID.
