A method and device for managing an emergency procedure of an emergency transaction mode that can be activated in the event of a computer attack on or a failure of a transaction network. The method may be carried out by an electronic device suitable for performing a transaction in a normal mode or in the emergency mode. The method performs operations that may include receiving an activation command for activating the emergency mode procedure, where the command includes an identifier of the procedure and first encrypted data; verifying the activation command, which includes verifying the first encrypted data; and if verification of the command is successful, activating the emergency procedure.

Method of managing an emergency mode transaction procedure, and an associated device

A method for collecting transaction history data and an associated terminal device. The method may include: collecting on-line, from a remote server (SV), first history data (DT) representative of at least one transaction associated with a user account (); communicating contactlessly with a smart card (), during which the terminal (T) recovers second history data (DH) stored locally in a memory () of the smart card, the second history data being representative of transactions processed by the smart card in association with the user account (); and analyzing, during which the terminal (T) aggregates the first and second history data in order to obtain up-to-date history data. It is thus possible to generate transaction-following data from the up-to-date history data.
