Device for determining a transactional device, corresponding method and computer program

An electronic device for determining a type of transactional device used to carry out a transaction, the electronic device comprising:

• a data processor;
• a memory;
• an optical sensor;
• and
• a set of transactional interfaces,
• wherein the memory stores instructions which when executed by the data processor configure the electronic device to:
• obtain at least one recording coming from the optical sensor, said recording being obtained when a user holds said transactional device in hand;
• determine at least one confidence score, said at least one confidence score being associated with at least one corresponding input for activating at least one transactional interface of the set of transactional interfaces of said electronic device;
• and
• activating at least one transactional interface associated with said at least one input of the structure of data for activating transactional interfaces of the set of transactional devices of the electronic device, as a function of a descending order of value of score of said at least one confidence score.

A non-transitory computer-readable medium comprising program code instructions stored thereon, which when executed by a processor of an electronic device configure the electronic device to:

• determine a type of transactional device used to carry out a transaction by:
• obtaining at least one recording coming from an optical sensor of the electronic device, said recording being obtained when a user holds said transactional device in hand;
• determining at least one confidence score, said at least one confidence score being associated with at least one corresponding input of a structure of data for activating transactional interfaces of a set of transactional devices of said electronic device;
• and
• at least act of activating at least one transactional interface associated with said at least one input of the structure of data for activating at least one transactional interface of the set of transactional devices of the electronic device as a function of a descending order of value of score of said at least one confidence score.
