Answer:
require direct line-of-sight scanning.
Explanation:
Unlike radio frequency identification (RFID) tags, bar codes require direct line-of-sight scanning. Meaning you need a device that can scan the bar code and the scanner needs to be directly pointing at the barcode without anything in the way. This is because bar codes work by embedding the information in a design of lines that need to be scanned to retrieve the information. If anything gets in the way it interrupts the scanning process and the data is not correctly transmitted. RFID tags on the other hand do not need a direct line of sight since the information is transferred through radiofrequency. This allows the data to be transferred without a line of sight and at a distance of up to 300ft.
