A data carrier-based electronic goods/services procurement/purchasing system in which transactions with multiple goods and services providers (container partners) are handled by means of data carrier cards (2) via a system computer (12, 24), wherein in the system at least one memory location (6) for user-individual data is provided on the data carrier card (2); a memory location (8) for user-individual container data is provided in the system, i.e. for data suitable for linking the user to multiple providers (container partners) in the purchasing system; at least one linking logic (25), arranged on the card (2) or at some other system location (24), which on user access to the system and/or when a user transaction with a container partner has already been handled, automatically prompts at least one further action by the same or other container partner depending on the user-individual data and/or transaction data of the user, the further action being communicated to the user via a data output (16) incorporated in the system; the linking logic basing decisions on the memorized user-individual data (6) and/or on the memorized user-individual container data (8) and on the access features predefined at the container partner end.
