Method for monitoring products in a refrigerator, wherein the refrigerator () comprises at least a compartment () for containing products (), a door () adapted to close said compartment () and radio frequency transmission means () adapted to communicate with a plurality of transponders () associated with said products () to detect the presence of said transponders () into the compartment (), each transponder () being able to send a specific identification code, the method comprises: detecting said transponders in static condition of closed door (C), detecting said transponders during a time period (T) which represents a dynamic phase of door opening (C), detecting said transponders during a second time period (T) which represents a dynamic phase of closing door (F), comparing said transponders () detected in static condition (C) and in dynamic condition (F, F), and their time events of detection for determining the transponders introduced and extracted, respectively, from the refrigerator during the condition of open door (C).

Apparatus for monitoring items passing through an entry/exit opening in a delimited space, comprising: Control means () are provided to continuously store and/or update the time-based detection events of the transponders and the time-based variation events of the signal transmitted by the sensors (), said control means () being adapted to compare said time-based signal-variation events to determine an opening passing-through time interval (T), and to compare the time-based detection events of the transponders with the passing-through time interval (T) to determine the transponders that have passed through the opening.
