<p>The invention concerns a method for authorising and controlling with a memory card the dispensing and metering of a least a flux, using any type of meter (9, 11) delivering a signal representing said consumption to an electronic management unit (4) connected to a memory card (2) reader (31) and for controlling the opening and closing of at least a member for interrupting (10, 12) the dispensing (5, 6) of said flux. The invention is characterised in that the memory card (2) is loaded with value units, and is introduced into the electronic unit (4) reader (31), all the value units contained in the card memory are unloaded into the memory of the electronic unit with an identification code particular to the card (2); the card (2) is then removed from the reader (31) and the dispensing of said flux is authorised by opening the member interrupting the dispensing (10, 12); the number of value units corresponding to the consumption of the flux is deducted in the electronic unit memory (4).</p> |
