SYSTEM FOR SECURE TRANSACTIONS OF CARD-BORNE VALUE UNITS

摘要

The invention concerns a system for secure transactions of card-borne value units. The system comprises a card peripheral for establishing a connection with the card and comprising a transparent mode, a terminal connected to the card peripheral, a host device connected to the terminal. The host device comprises a transaction application for processing value units on the card and cryptographic means for reading and/or writing value units and other data on the card. The card peripheral operates in transparent mode. The terminal redirects the data from or to the card peripheral to the host device. The host device interfaces with the card via commands and data exchanges. The invention is particularly useful for recharging a smart card in particular from computer means available to the user owning said card and an ordinary smart card reader.
