A jackpot system used in casinos for allocating the wins from at least one jackpot to players playing at a plurality of gaming positions. The gaming positions are associated with a computer network including a computing engine having a memory for receiving inputs from the gaming positions and at least one output for communicating information to the players. At least one paytable is stored in that memory or in another memory associated with the computer network. The paytable can be configured by an operator and has a plurality of possible winning entries and wins associated with the winning entries. A selection generator is triggered at least once, via the computer network, by a trigger input generated in response to the playing of each game of a group of selected games to generate a selection.

A chip card is operable in a contactless and contact-coupled mode. For operation in the contactless mode, the chip card has an antenna coil and rectifier. In the contactless mode, the chip card receives an AC signal. The rectifier provides a rectified received AC signal. The rectified signal is used for powering internal circuitry of the chip card. The chip card further has a recognition circuit that recognizes whether an AC signal is actually received by the antenna coil. If the AC signal is recognized, the recognition circuit switches the chip card to the contactless mode. If no AC signal is recognized, the recognition circuit switches the chip card to the contact-coupled mode.
