A system for identifying or assisting in identifying a product or a set of products of a user, such as products corresponding to the contents of a meal tray, said system for identification or assistance in identification comprising: - a counter for receiving said product or set of products; - a lighting system for lighting the counter; - a plurality of image acquisition devices (41, 42, 43) pointing toward the counter so as to acquire images of said product or set of products at different viewing angles; - a display screen; characterized in that the system for identification or assistance in identification also comprises: - a first database storing user account data, each user account comprising: ∘ an identifier of a user; ∘ a credit or debit balance value; - an identifier device enabling the user to be identified; - a control device configured to: - acquire an identifier of the user; - determine whether the acquired identifier of the user corresponds to the identifier of the user of a stored user account; - acquire images (401, 402, 403) of said product or set of products by using said image acquisition devices (41, 42, 43); associate the acquired images (401, 402, 403) with the identifier of the user in a second database, and in that the system for identification or assistance in identification comprises a back face that extends substantially orthogonally to the counter, the back face absorbing daylight less than the counter; and in that said image acquisition devices (41, 42, 43) comprise a first image acquisition device whose optical axis is oriented perpendicularly to the counter, and second and third image acquisition devices (42, 43) arranged on either side of a plane passing through the optical axis of the first image acquisition device and perpendicular to the back face, the optical axes pointing toward the counter and sloping in mutually opposite directions relative to the optical axis of the first image acquisition device. said system for identification or assistance in identification comprising: - a counter for receiving said product or set of products; - a lighting system for lighting the counter; - a plurality of image acquisition devices (41, 42, 43) pointing toward the counter so as to acquire images of said product or set of products at different viewing angles; - a display screen; - a counter for receiving said product or set of products; - a lighting system for lighting the counter; - a plurality of image acquisition devices (41, 42, 43) pointing toward the counter so as to acquire images of said product or set of products at different viewing angles; - a display screen; characterized in that the system for identification or assistance in identification also comprises: - a first database storing user account data, each user account comprising: ∘ an identifier of a user; ∘ a credit or debit balance value; - an identifier device enabling the user to be identified; - a control device configured to: - acquire an identifier of the user; - determine whether the acquired identifier of the user corresponds to the identifier of the user of a stored user account; - acquire images (401, 402, 403) of said product or set of products by using said image acquisition devices (41, 42, 43); - a first database storing user account data, each user account comprising: ∘ an identifier of a user; ∘ a credit or debit balance value; ∘ an identifier of a user; ∘ a credit or debit balance value; - an identifier device enabling the user to be identified; - a control device configured to: - acquire an identifier of the user; - determine whether the acquired identifier of the user corresponds to the identifier of the user of a stored user account; - acquire images (401, 402, 403) of said product or set of products by using said image acquisition devices (41, 42, 43); associate the acquired images (401, 402, 403) with the identifier of the user in a second database, and in that the system for identification or assistance in identification comprises a back face that extends substantially orthogonally to the counter, the back face absorbing daylight less than the counter; and in that said image acquisition devices (41, 42, 43) comprise a first image acquisition device whose optical axis is oriented perpendicularly to the counter, and second and third image acquisition devices (42, 43) arranged on either side of a plane passing through the optical axis of the first image acquisition device and perpendicular to the back face, the optical axes pointing toward the counter and sloping in mutually opposite directions relative to the optical axis of the first image acquisition device.
