Abstract
The invention is a method for preventing the loss of a smart card (10) of a user (50) in which upon detection of a communication between the smart card and a terminal (20) for performing a transaction, the smart card starts emission of a broadcast signal during a preset period. A portable apparatus (30) of the user evaluates an assessed distance between the smart card and the portable apparatus by analyzing parameters of the broadcast signal. The portable apparatus triggers a loss warning if the assessed distance reaches a threshold before a time equal to the preset period. The smart card uses an internal energy source (11) to power the emission of the broadcast signal and the preset period is longer than a duration during which the transaction is carried out.
