EC-Council Official Curricula Certified Cybersecurity Technician v1 https://online.vitalsource.com/reader/books/9781635679533/ Module 13 Page 1562 QR Codes and Barcodes: These codes are machine-readable tags that contain information about the product or item to which they are attached. A quick response code, or QR code, is a two-dimensional code that stores product information and can be scanned using smartphones, whereas a barcode comes in both one-dimensional (1D) and two-dimensional (2D) forms of code.

QR codes and barcodes: These are commonly used in retail environments for product identification and pricing. The process involves scanning the codes with a machine-readable scanner, which reads the product details and calculates the total bill.

Wireless doesn't mean to be readio frequency alone, it can be optical bar code reader too. So As per CCT book machine radable tag most of the time QR codes or 2D bar code. Thus, correct answer is D.

QR Codes and barcodes are listed under short-range wireless communication (page 1562), and the description matches the question perfectly. There are no tags used in NFC (maybe RFID, but not NFC), NFC communication is done between two devices to "exchange" information, RFID is for identification... IMHO
