Abstract (en)

[origin: WO9964996A1] A system comprising a card reader (1) with a terminal (3) and a security module (4) accepts a portable preloaded IC-card (2) having an integrated circuit (8) with a lock (9) to prevent unauthorised use of the IC-card (2), and a cash value unit counter content (10), which represents the cash value and is devaluated during a transaction at a stand alone point of sale. The IC-card (2) generates a card random number, whereas the security module (4) generates a security module random number. The IC-card (2) encodes the security module random number into a card signature, and the security module (4) decodes the card signature again to verify the authenticity of the IC-card (2). The security module (4) creates a security module signature from the card random number being decoded by the IC-card (2) to verify the authenticity of the security module (4). If the mutual authentication is positive, the lock (9) allows the payment transaction to take place.
