Abstract: Electronic equipment, such as a mobile phone, PDA or other device, is operative to transmit information to another electronic equipment when the two are paired caused by moving them, e.g., shaking, at substantially the same frequency and amplitude. The transferred information may be contacts or other information. The electronic equipment include a motion transducer providing motion signals representing motion and a comparator that compares motion signals to determine whether substantially the same motion is occurring to both electronic equipment; if affirmative, a substantially secure communication link is established over which information may be transmitted between electronic equipment. A method of transmitting information includes detecting occurrence of motion and in response thereto transmitting information.
