Radio Frequency Identification technology has been a focal point of recent innovations in home appliance. The smart fridge is now a prominent area of interest for both academics and businesses for its potential to transform our kitchen experience; however the current market price of a smart fridge is highly expensive and out of budget for the average consumer. A close examination of possible factors shows that while the price of RFID components is constantly decreasing, overall cost remains high enough to make the smart fridge a luxury product. Implementing adaptive characteristics in high frequency RFID reader/tag will increase the capability to adapt to specific environments such as humidity and different interferences with fridge environment. In this paper, we introduce a low cost enhanced design smart fridge based on adaptive high frequency RFID combined with the traditional smart fridge features and a freshness detection capability. Our design not only outperforms the existing ones in price but also presents the consumer with information on the freshness of fruits and vegetables.
