A payment system for use with electronic payment devices. Electronic payment cards (e.g. "Smart Cards"), may be used with one or more payment stations (e.g. electronic cash registers). The payment stations are designed for receiving, during a payment transaction, a monetary value by crediting, in the payment station, a first value, and debiting, in the payment means, a second value corresponding to the first value. The first and second values may be expressed in different calculation units, such as currencies of different countries. The system furthermore offers a payment device for application in such a system, and a method for effecting a payment transaction with an electronic payment means.
