Device for protecting computer confidential data exchanges for permitting remote payment via communication media; requires secondary device to use of support before or during exchange of data

摘要

A computer system permits communication with or without electric contact with another computer system with which it can exchange some data and/or to achieve a complete operation like a payment, or an authorization of access. The support carrier's identification requires a secondary device to use of the support before or during an exchange of data. Alternatively it initiates the exchange, with or without electric contact with the support.
