Abstract

The present invention provides a method to reinforce the security of a conventional transaction performed by a Short-Range (SR) communication-enabled chip card, wherein the chip card is paired with at least one SR communication-enabled handset, the method comprising the steps of: initiating the conventional transaction between the chip card and a reader; wherein the method is characterized in that: sending, by the chip card, an authentication request to at least one of the at least one paired handsets over an established Short-Range (SR) communication channel; receiving, by a paired handset, the authentication request and computing an authentication result granting or refusing the transaction; sending, by the handset, an authentication response to the chip card over the established channel, the authentication response comprising the authentication result; and continuing or stopping, by the chip card, the conventional transaction with the reader depending on the authentication result.
