Method for activating a portable contactless payment object of the timepiece or piece of jewellery type able to participate in the making of an electronic payment by tokenisation, the method comprising the following steps: - obtaining of a payment token by a mobile electronic device coming from a server of a trusted third party providing a payment service by tokens, and - configuration of the portable object with a view to use thereof providing a transmission of said token included in the electronic device to said portable object by means of an activation terminal, said terminal comprising a first communication module including an NFC proximity communication unit and a second communication module comprising a communication unit for receiving and sending data remotely via a wireless network of the Wi-Fi or Bluetooth type, and in that said step of configuring the portable payment object comprises a substep of arranging this portable object on a data transmission zone defined on/in the activation terminal so as to guarantee an optimum exchange of data between an NFC proximity communication module of the portable object and the first communication module; said obtaining step comprising: - a substep of digitisation by the electronic device of a first graphical representation included on the activation terminal, said first graphical representation comprising a matrix code; - a substep of decoding of the matrix code with a view to obtaining binary information sequences including data relating to a location of a digital file for configuration of the electronic device; - a substep of generation, by the electronic device configured by the digital file, of a request to obtain this payment token comprising data for production of said token comprising at least one banking data item; - a substep of transmission of the payment token by the server of the trusted third party to the electronic device, this transmission substep comprising a phase of generating the payment token by a processing module of the server of the trusted third party; said step of configuring the portable object comprising: - a substep of digitisation by the electronic device of a second graphical representation included on the activation terminal, said graphical representation comprising a matrix code; - a substep of decoding of the matrix code with a view to obtaining binary information sequences including data relating to a configuration of a communication link between this electronic device and the activation terminal, and in that, during said configuration step, a processing unit of the electronic device transmits, to the second communication module of the activation terminal via its communication interface, the token generated by the server of the trusted third party, said token next being transmitted by the first communication module of the activation terminal to the portable object via the NFC proximity communication module of this portable object. - obtaining of a payment token by a mobile electronic device coming from a server of a trusted third party providing a payment service by tokens, and - configuration of the portable object with a view to use thereof providing a transmission of said token included in the electronic device to said portable object by means of an activation terminal, said terminal comprising a first communication module including an NFC proximity communication unit and a second communication module comprising a communication unit for receiving and sending data remotely via a wireless network of the Wi-Fi or Bluetooth type, and in that said step of configuring the portable payment object comprises a substep of arranging this portable object on a data transmission zone defined on/in the activation terminal so as to guarantee an optimum exchange of data between an NFC proximity communication module of the portable object and the first communication module; - a substep of digitisation by the electronic device of a first graphical representation included on the activation terminal, said first graphical representation comprising a matrix code; - a substep of decoding of the matrix code with a view to obtaining binary information sequences including data relating to a location of a digital file for configuration of the electronic device; - a substep of generation, by the electronic device configured by the digital file, of a request to obtain this payment token comprising data for production of said token comprising at least one banking data item;
