Abstract

DC60 (25/05/42) A system that at least consists of a card reader (1) with terminal (3) and a security module (4) that accepts pre-recorded IC cards. A portable (2) with an integrated circuit (8) with an insert (9) to prevent unauthorized use of the IC card (2) and a counter body of cash value units (10), which represents Cash value The IC card (2) generates random numbers, where the security module (4) generates random numbers, the IC card security module. (2) encode a random number, a security module into a card signature and a security module (4) decrypt the card signature again (2) Security Modules (4) Create a signature module to provide security from a number. A random number card decoded by an IC card (2) for verification. The module's certification condition provides safety (4) .If the mutual approval is correct, the insert (9) will allow a replacement item. Convert to Pay (Fig. 1) A system that at least consists of a card reader (1) with a terminal (3 and a security module (4)) that accepts pre-recorded IC cards that Carry (2) at the integrated circuit (8) with insert (9) to prevent unauthorized use of the IC card (2) and the cash value unit counter (10) representing the cash value. The IC card (2) generates random numbers, where the security module (4) generates random numbers, the IC card security module. (2) enter the code random number to provide security into the card signature and security module (4) decrypt the card signature again (2) Security Modules (4) Create a signature module to provide security from a number. A random number card decoded by an IC card (2) for verification. The module's certification condition provides safety (4) .If the mutual approval is correct, the insert (9) will allow a replacement item. Convert to pay (Fig. 1).

Claims (1)

1. A system that at least consists of a card reader (1) with an electronic terminal (3) and a module to provide absolute security. At least one module (4) and a portable pre-recorded IC card (2) with an integrated circuit (B) with a lock (9) to prevent IC card use (2). And a non-volatile memory segment (20) to store the value of an existing IC card (10) with a way to reduce its value. The existing IC cards are down respectively during which they are available. Replacement item Converted at the independent unit point (56) attached to the terminal (3 tags:
