The invention relates to a pay terminal that can be coupled to a pay card having at least one value unit and to a background terminal. The terminal comprises a control unit having means for changing the value units disposed on the pay card and a communication unit having means for bidirectional transmission of information between the pay card and the background terminal, whereby the value units to be transmitted to the pay card (3) can be determined by running a treed decision-making network (5), whereby the decision-making network (5) consists of a plurality of decision-making nodes (N) that are linked to one another and to which a given condition (C) and one or two decision-making rules (R) are assigned. Depending on the existence or absence of condition (C), another decision-making node (N) can be activated. |
