The correct answer is A. data carriers.
AIDC stands for Automatic Identification and Data Capture. It is a technology that uses electronic methods to automatically identify and capture data about physical objects. AIDC technologies include barcodes, RFID tags, and biometrics.
Barcodes are a type of optical machine-readable code that represents data in a visual format. They are used to identify products, assets, and people. RFID tags are a type of radio frequency identification tag that can be attached to or incorporated into a product or asset. They are used to track and monitor the movement of goods and people. Biometrics are a type of physical or behavioral characteristic that can be used to identify an individual. They are used to authenticate users and protect against fraud.
AIDC technologies are used in a variety of industries, including manufacturing, retail, healthcare, and transportation. They can help to improve efficiency, accuracy, and security.
