Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

UPC (Universal Product Code) is a barcode standard used for product identification in retail, not a data automation source. POS terminals, OCR (Optical Character Recognition), and keyboards are all input methods that can be used for automated data collection and entry. UPC is an identification system, not a data collection/automation device itself.
