Abstract: Provided is a method for managing a biometric sensor configured to collect a captured biometric data and a secure element able to communicate with the biometric sensor through a communication channel. The method comprises receiving a specific data by the biometric smart card, and checking the specific data by using a control data pre-stored in the biometric smart card. Only if said checking is successful, it then executes an erasing command for removing said reference biometric data from the biometric smart card and a disabling command for permanently deactivating the communication channel.

Abstract: A method for enrolling a holder of a biometric transaction device includes the following step: storing at least one biometric pattern in the device. The method further includes the following steps: a) providing the holder with a portable, mobile power connector, configured to trigger the storing; b) and/or activating the biometric pattern, the activation being carried out in response to or in association with a successful authentication of the holder. A corresponding system is also enclosed.
