- These polarizing means thus make it possible to help the user to identify the "active" faces of the equipment, that is to say the faces associated with short-range communication means.
- these polarizing means may be mechanical components preventing contact between two faces that can not cooperate with each other.
- the magnets DET and DET-H may be replaced by snap-fastening means (or "clip") consisting of a protuberance and a cavity, the protuberance, for example on the face F1, being housed in a cavity arranged on the face F2.
- the equipment E1 is a gateway of a local network and the equipment E2 is to be connected to the local network.
- the equipment E1 comprises a file reader (for example of multimedia content) and the equipment E2, by connecting to the equipment E1, receives, from it, descriptive data relating to this file that it displays on an SCR2 screen it contains (for example for multimedia content such as audio content: the name of a piece of music, its author, an image (corresponding for example to an album cover), the duration of the piece, its coding format, etc.).
- a file reader for example of multimedia content
- the equipment E2 by connecting to the equipment E1, receives, from it, descriptive data relating to this file that it displays on an SCR2 screen it contains (for example for multimedia content such as audio content: the name of a piece of music, its author, an image (corresponding for example to an album cover), the duration of the piece, its coding format, etc.).

- a processor PROC1 of the equipment E1 (and / or a processor PROC2 of the equipment E2) command (s) a putting in availability of the transmission / reception means ER1 (and / or ER2), to initiate a communication in the transmission step S26.
- the equipment E1 and / or the equipment E2 If the reception of data by the equipment E1 and / or the equipment E2 does not start in a predefined time following the detection of the contact, or if the received data do not respect an expected exchange format (test T23) , the equipment E1 and / or E2 leaves its reception mode and ignores the received data (step S24).
- the equipment E1 and / or E2 receives the data and stores, at least temporarily, the received data for further processing (step S25).
- the pairing between the equipment E1 and E2 is achieved by simply detecting a contact between the two devices and that the pairing triggers the start of the data transmission between the two devices.

- the communication channel is thus effective between the two devices E1 and E2 and first data can be received by the equipment E2 (step S31).
- the equipment E2 conducts a T32 self-test to determine if it is connected to the local network. If this is not the case, the equipment E2 then seeks the test T34, in its memory MEM2, whether or not it has a security key WEP to connect to the local network. If the equipment E2 does not have a WEP key in memory, it sends a request to the equipment E1 to request the transmission of a valid security key, in a step S36.
- the equipment E1 determines whether it has a valid WEP key. If the test T39 is positive, the equipment E1 transmits the valid WEP key to the equipment E2 during a step S37. The equipment E2 stores the key WEP received during a step S39 in its internal memory MEM2 for future reuse.
- the equipment E2 is able to connect to the local wireless network of the equipment E1, in a step S38.
- the equipment E2 is already connected to the local network, or if it already has a valid key in memory when reconciling with a compatible equipment, it is useless to make a request to the second equipment to obtain a WEP key, and the method then leads to the steps S33 and S35 respectively.

- the equipment E2 can determine, according to the first data received, whether the equipment E1 is capable of transmitting data intended to be displayed on the screen SCR2 that the equipment E2 carries, on the occasion of a first test T42. If the main function of the equipment E2 is to display such data (for example information relating to a multimedia content being read) and the equipment E1 is able to communicate such data, the process continues. by step S44, during which the equipment E2 transmits to the equipment E1 a request to obtain data relating to a content being read by the equipment E1 for display on the display screen SCR2 . In the opposite case (if the equipment E1 is not arranged to communicate such data), no request is made (step S43).
- the equipment E2 receives the required display data.
- the E2 equipment processes this data to prepare for display. It can be provided in test T45 that the equipment E2 determines the opportunity to request a download of additional data during a step S46, for example through the Internet, to enrich the data transmitted by the equipment E1 .
- equipment E2 can determine in test T45 whether a download of metadata relating to a content being read by the equipment E1 could enrich the display data transmitted by the equipment E1.
- the data transmitted by the equipment E1 may include a URL link for a download of such metadata.
