), each machine being connected to a transcriber (210) of data onto a gambling card (CJ2), the machines being connected in a secured network with a central processing unit (1) by link means (123), the method having the following steps, during a gambling operation;
reading data stored in a gambling card, particularly an identification number (Id) of the card (CJ1) and/or data (S, Op1, Op2, Opx) representing the value units debited and/or credited during the preceding gambling operations, the method being characterized by the following steps;
exchanging data between the machine (200) and a database (BD) of the central processing unit (1) by means (123) linking the secured network, particularly data representing the balance (S) of the value units and/or the identification number (Id) of the card; and
checking that the data stored in the gambling card (CJ1) correspond to the data in the database (BD) in order to monitor the integrity of a system constituted by such a card, such a machine, the network, and the central processing unit.

Abstract
The invention concerns slot machines, such as jackpot or black jack and other casino gambling machines. The machines are designed to operate with gaming cards (CJ1), such as chip cards, and are connected by network to a central management unit (1). The invention is characterised in that the central management unit comprises a database (BD), wherein are stored data corresponding to those stored on the gaming cards such data concerning the gamester and card identification data (Id) and data (S, Op1, Op2) concerning the account balance stored in the card (CJ1). The procedure consists in verifying the card data with respect to the central management unit database to ensure the integrity of such a gambling machine system operating with chip cards or contactless cards.

16. Secured system for monitoring transfers of value units between a plurality of gambling cards (CJ) and a plurality of gambling machines (200, 300), each machine being provided with a transcriber (210, 310) able to debit value units of a gambling card (CJ), the machines being connected in a secured network with a central processing unit (1) by link means (123), whereby a gambling card (CJ1) stores data (S, Op1, Op2, Opx) representing gambling operations conducted, particularly data identifying the card (Id) and data representing the balance (S) of the value units debited and/or credited during previous gambling operations, characterized in that the central processing unit (1) has a database (BD) that in parallel stores the data (S1, Op101, Op102, Op10x) representing gambling operations carried out, particularly card identification data (Id1, Id2, Idn) and data representing the balances (S1, S2, Sn) of the value units debited and/or credited during previous gambling operations and in that the monitoring means (BD) check that, for an identified card, the database (BD) data and the card (CJ1) data correspond, particularly that the data (S, S1) representing the value unit balance correspond, in order to verify the integrity of the system.
