IGNORE ANYONE WHO DOES NOT CITE THE OFFICIAL CURRICULA Vendor Certifications exams are based on the vendor's official training material, not internet forum troll opinion consensus. The wording below is from the book, and matches the wording in the question. 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.

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

QR codes and barcodes are not short-range wireless communication technologies. They are considered optical scanning technologies.
