Method and system for data communication with an inaccessible electronic device

摘要

The method involves receiving signals conveyed by an electrical connection lead (3) i.e. power cable, and fitting a radiofrequency interface with electrical contacts (LA, LB) in an electronic radiofrequency device (2). Signals are extracted from the electrical lead, and signals resulting from the extracted signals are injected in the interface with the electrical contacts, where the signals resulting from the extracted signals are presented in the form of frames of radiofrequency signals that are compatible to ISO/ IEC 14443 standard. An independent claim is also included for a radiofrequency communication system comprising signal generation units.
