This paper presents a system allowing rapid prototyping and development of new SMART RFID sensing applications. The proposed system is composed of a new low-power passive 13.56 MHz RFID Analogue Front End (AFE) chip, sensors, rechargeable battery a micro-controller and memory. The AFE was designed and fabricated successfully based on using a 0.35 um CMOS technology. To allow re-charging a battery through the RF field, a new battery charger is designed and integrated within the AFE, this leads to a selfpowered system which is a new benefit in the RFID sensing and continuous monitoring. As application, a Shelf Life Time Tracker (SLTT) is developed. The SLTT is a supervision RFID system monitoring quality changes during transport of perishable foods. When addressed, the system will give a shelf life prediction based on the used quality model. This system will be used to make appropriate management decisions that maintain and increase value across a supply chain. In addition to the shelf life prediction, the SLTT allows the conditions monitoring (temperature, humidity, etc.).
