Method for detecting the handling of products on a display stand by one or more persons , said products being provided with electronic tags each containing a unique identifier, each person being associated with an object communicating by radio frequency and periodically transmitting a signalling signal, said display stand comprising a plurality of near-field communication antennas and at least two radio frequency receivers being placed close to the display stand, a central processing unit being connected to said display stand and to said receivers in order to carry out said method which includes repeating the following steps: - a product inventory step during which the display stand sends and receives messages via the near-field communication antennas so as to identify and locate the electronic tags of products present on the display stand, - an inventory comparison step during which the central processing unit determines, between two successive inventory steps, a difference among the products present on the display stand, said step identifying a product removed from or added to said display stand and determining a position on said display stand where said product has been removed or added, - a person locating step during which each of the radio frequency receivers receives a signalling signal transmitted by an object communicating by radio frequency, measures the strength of the signal received and determines the position of the communicating object associated with a person by triangulation depending on the position of the radio frequency receivers and on the strength measurement of the signal received, - an association step during which the central processing unit associates a person with a product when the position of the communicating object associated with said person is located close to the position of the identified electronic tag of a product which has been removed from or added to the display stand, said associated person being considered to have removed the product from or put it back on the display stand. - a product inventory step during which the display stand sends and receives messages via the near-field communication antennas so as to identify and locate the electronic tags of products present on the display stand, - an inventory comparison step during which the central processing unit determines, between two successive inventory steps, a difference among the products present on the display stand, said step identifying a product removed from or added to said display stand and determining a position on said display stand where said product has been removed or added, - a person locating step during which each of the radio frequency receivers receives a signalling signal transmitted by an object communicating by radio frequency, measures the strength of the signal received and determines the position of the communicating object associated with a person by triangulation depending on the position of the radio frequency receivers and on the strength measurement of the signal received, - an association step during which the central processing unit associates a person with a product when the position of the communicating object associated with said person is located close to the position of the identified electronic tag of a product which has been removed from or added to the display stand, said associated person being considered to have removed the product from or put it back on the display stand. <EOS>
