Which device reads bar codes?

• A. bar code reader
• B. barcode scanner
• C. QR reader
• D. image scanner

Answer: (A)

Reading barcodes means converting the pattern of bars and spaces into usable data. A bar code reader is the device designed to decode that pattern and send the resulting information to a computer or system. While barcode scanners perform the same basic function, the term bar code reader is the typical label used in many contexts for this device. A QR reader focuses on QR codes, a specific type of barcode, so it wouldn’t handle all barcode formats. An image scanner just captures a digital image and doesn’t decode barcode data by itself.
