Used-by dates printed on packaging are critical for ensuring product safety, regulatory compliance, and accurate stock rotation in food, pharmaceutical, and consumer goods industries. Poor print quality, smudging, or inconsistent coding can lead to unreadable dates and potential distribution errors.

A 2D smart vision camera enables OCR-based inspection of used-by dates directly on packaging lines by capturing high-resolution images and extracting printed date information in real time. It verifies the presence, format, and readability of expiry or used-by dates against predefined standards, ensuring only correctly labeled products proceed to packaging, storage, or shipment. This improves compliance, reduces manual checks, and enhances overall production quality control.
