Question: 1 / 400

Which of the following is true about bar codes and RFID tags and their respective scanners?

Bar codes require a direct line of sight and RFID tags do not.

The correct information indicates that bar codes require a direct line of sight for the scanner to read them, as they depend on optical scanning. The scanner emits light that is reflected back from the barcode, and this requires the barcode to be visible in the scanner's field of view. In contrast, RFID tags function differently; they can be scanned without direct line of sight because they communicate via radio waves. This allows RFID scanners to read the information from RFID tags even if they are obscured by materials or are not directly in front of the scanner.

Understanding these differences is crucial in logistics and inventory management, as it influences how items are scanned, tracked, and managed throughout the supply chain. The ability of RFID technology to work without line of sight offers significant advantages in efficiency and convenience over traditional barcoding methods.
