Product counterfeiting has become an emerging brand-security issue for commodity consumables. In recent years, innovative technologies have been introduced in response to this important issue. Because of their sensitivity, convenience to management, and relative rapid results, sensors have drawn attention for their application in the fight against counterfeiting. In this article, we provide an overview of the latest development in sensors that can be used for anti-counterfeiting purposes. We also focus on introducing various innovative sensors that could be employed in smart packaging, including biosensors, nanosensors, and radio frequency identification (RFID) sensors. At the same time, the article discusses current and potential applications of the sensors, challenges of implementing them, and an outlook of sensors in packaging industry for anti-counterfeiting strategies.
