Abstract
Gaming machines provided with mechanical counters according to the regulations, to which there is grafted an electronic payment mechanism working on the basis of a chip card. It consists in diverting a certain number of links of the units of the machine by the electronic payment mechanism to enable wagers to be placed and payments to be made through the chip card, without the receiving or issuing of tokens and, preferably, without the modifying of the contents of the TOTAL IN and TOTAL OUT counters. A downgraded version modifies the contents of these counters and the balance of the feeder box containing the coins is obtained by modifying the formula used to compute this balance. It enables the efficiency of gaming machines to be raised.
