Abstract: A first near-field communication device is remotely powered by a second near-field communication device. The first near-field communication device receives from the second near-field communication device a frame indicating a failure of a data reception by the second near-field communication device. In response, at least one transmission parameter of the first near-field communication device is modified prior to another attempt of transmission of the data.

Abstract: A microcircuit card is provided with a fingerprint sensor. Customization of the microcircuit card is accomplished by the use of an exchange of data by near-field communications between the microcircuit card and a near-field communication device. A mechanical positioning system associated with the near-field communication device is configured to retain the microcircuit card such that the fingerprint sensor is accessible and near-field communication between the microcircuit card and the near-field communication device is assured. The mechanical positioning system may, in an example where the near-field communication device is a cell phone, be formed by a slot of a protective case for the cell phone.
