Silkron Smart RFID Fridge utilizes RFID technology to read the tags attached to the products. Users can hold, view and check on the details of the items and even put them back if it is not desired. The system will know what exactly has been taken out once the door of the smart fridge is closed then charge the actual amount accordingly. Only relying on the RFID reader that is embedded inside the vending fridge, it has lower maintenance cost and lower startup cost.
