Abstract
A method and a device for making available electric charge in order to charge an electronic card including a near-field communication module by way of a terminal. The terminal has what is known as a reader mode in which it is able to supply power to the card in near-field mode and receive data from the card. The method includes the following steps, on the terminal, set to reader mode, so as to generate an electromagnetic field able to charge such an electronic card: initializing the communication between the terminal and the card; receiving a message from the card, the message containing at least one datum telling the terminal that it should maintain the electric charge; and maintaining the electric charge while remaining in reader mode.

A method for making available electric charge in order to charge an electronic card comprising a near-field communication module by way of a terminal, the method being implemented on the terminal, which is set to a near-field reader mode so as to generate an electromagnetic field able to charge the electronic card:
- initializing a communication on a near-field channel between the terminal and the card, the terminal being configured to communicate wirelessly with the electronic card using a human body as part of the initialized near-field channel;
- receiving a message from the card, said message containing at least one datum telling the terminal that the terminal should maintain the electric charge;
- and
- maintaining the electric charge while remaining in reader mode;
- until an end of a first duration for which the electric charge should be maintained, or
- until obtaining a command to stop making the charge available;
- and
- then stopping making the charge available for the card.
A method for electrically charging an electronic card comprising a near-field communication module and a rechargeable battery by way of a terminal, which is set to near-field reader mode, the method being implemented on the card, when the card is located within the electromagnetic field generated by the terminal, and comprises:
- initializing a communication on a near-field channel between the card and the terminal, the electronic card being configured to communicate wirelessly with the terminal using a human body as part of the initialized near-field channel;
- transmitting a message to the terminal, said message containing at least one datum telling the terminal that the terminal should keep making electric charge available;
- and
- adapting a received charge in order to charge the battery;
- and
- transmit a first duration for which the electric charge should be maintained or a command to stop making the charge available for the card.
A terminal comprising:
- a near-field communication device, a memory and a processor that are configured so as, when the terminal is set to reader mode, in order to generate an electromagnetic field able to charge an electronic card comprising a near-field communication module, to:
- initialize a communication on a near-field channel between the terminal and the card, the terminal being configured to communicate wirelessly with the electronic card using a human body as part of the initialized near-field channel;
- receive a message from the card, said message containing at least one datum telling the terminal that the terminal should maintain the electric charge;
- and
- maintain the electric charge while remaining in reader mode:
- until an end of a first duration for which the electric charge should be maintained, or
- until obtaining a command to stop making the charge available;
- and
- then stopping making the charge available for the card.
An electronic card comprising:
- a near-field communication device-, a rechargeable power supply, an adaptation circuit, a memory and a processor that are configured so as, when the card is located within the electromagnetic field generated by a terminal, to:
- initialize a communication on a near-field channel between the card and the terminal, the electronic card being configured to communicate wirelessly with the terminal using a human body as part of the initialized near-field channel;
- transmit a message to the terminal, said message containing at least one datum telling the terminal that the terminal should keep making electric charge available;
- adapt a received charge in order to charge the battery;
- and
- transmit a first duration for which the electric charge should be maintained or a command to stop making the charge available for the card.
A non-transitory computer-readable medium comprising code instructions stored thereon, when the instructions is executed by a processor of a terminal, perform a method for making available electric charge in order to charge an electronic card comprising a near-field communication module by way of the terminal, the method being implemented on the terminal, which is set to a near-field reader mode so as to generate an electromagnetic field able to charge the electronic card:
- initializing a communication on a near-field channel between the terminal and the card, the terminal being configured to communicate wirelessly with the electronic card using a human body as part of the initialized near-field channel;
- receiving a message from the card, said message containing at least one datum telling the terminal that the terminal should maintain the electric charge;
- and
- maintaining the electric charge while remaining in reader mode:
