description PCT No. PCT/FR95/00151 Sec. 371 Date Jul. 30, 1996 Sec. 102(e) Date Jul. 30, 1996 PCT Filed Feb. 8, 1995 PCT Pub. No. WO95/22125 PCT Pub. Date Aug. 17, 1995A method of transaction replenishes a microprocessor-based card. The card computes a certificate of authenticity on the basis of data elements that it contains and that include the contents of its counter of the number of replenishment operations and its identification number. These data elements enable the card to verify its entitlement to be replenished. The card increments its counter of the number of replenishments. A replenishment terminal reads the identification number of the card and transmits to the card the data elements that pertain to it and that comprise the certificate of authenticity corresponding to it for the cycle in progress. The received certificate is compared with a certificate computed by the card. When the certificates are equal, the card accepts a replenishment of units.
