Abstract: A debug method implemented by a first near field communication (NFC) device includes a step of storing, in a memory of the first NFC device, one or more parameters which are associated with the operation of the first NFC device during a communication with a second distant NFC device. The first NFC device then uses an answer to select (ATS) communication, sent in response to receipt of an answer to select (ATS) communication, to send the stored one or more parameters to the second distant NFC device.

Abstract: A device facilitates personalizing an integrated circuit card including a fingerprint sensor. The device includes a support sheet, a first antenna located on top of and in contact with a surface of the support sheet, and at least one second antenna located on top of and in contact with the surface of the support sheet. The at least one second antenna is connected to the first antenna.

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.
