     DESCRIPTION OF THE INVENTION 
     Referring to FIGS. 1A and 1B, the device consists of a casing 1 adapted to receive a memory card 2 in a card slot 10. 
     The casing 1 is equipped with a keyboard 4, a screen 5, an infrared unit 6 with integrated receiver and transmitter components, and of an acoustic assembly composed of a speaker 8 and a microphone 9. The casing 1 is also provided with an optical receiver 7 capable of reading optical signals (bar codes, etc.). The microphone 9 and the speaker 8 may either be grouped together, or be separate, for example, by a linkage that would enable the speaker-microphone pair to be located conveniently, respectively on the microphone and on the speaker of a or a multi-chip type. For a better understanding, we will now explain the dual-chip concept. 
     One of the chips, functioning as permanent memory means, will remain permanently on the card, and will be able to retain permanent data, such as user information, type of subscription, address and/or a set of data that is not expected to change rapidly. The second chip, on the other hand, functioning as removable memory means, will be of removable and temporary-type, and as such, will be replaced regularly in order to follow the changes and the modification of variable parameters, such as time tables, prices and other periodic variations. 
     The subscriber will receive, for example, a new chip every six months, at the same time as all the other &#34;paper&#34; documents that each subscriber receives regularly. Once the removable chip 3 is snapped on, the apparatus will be able to communicate all kinds of data, at the request of the user, relating, for example, to the flights of an airline that could interest the subscriber. 
     The human-casing dialogue will be done by virtue of an alpha-numeric keyboard 4, and a screen 5 that will enable friendly communication. The casing-central computer dialogue will take place by virtue of a simple telephone, in accordance with the following modalities: 
     In order to make flight reservations, the user will type the destination in an abbreviated form (three letters, for example) on the keyboard 4, and then the desired time of the flight. The memorized data on the removable chip 3 will be consulted and brought up on the screen 5 according to the choice made, and the user will get all the details of his flight: flight number, time, price, etc. 
     The choice of the flight can also be done by the bar code scanner device 7 on any ad-hoc document The user will have to lift the telephone off the hook and press a key of the keyboard 4, and the apparatus will send the DTMF to execute the dialing command, and then, all the data will be sent by the speaker 8, placed in application against the microphone of the handset 12. The initial dialing will be done manually if the line is not connected to an electronic computer center. Once the data has been transmitted, the computer processes the data and either sends the confirmation, or suggests another flight, if the desired flight is full. To receive information, the microphone 9 must be placed in application against the speaker of the handset 12, this procedure can be done according to two modalities: 
     Either the apparatus is pressed on the microphone of the handset 12 for the transmission of data, and then replaced on the speaker, after the user has received a signal indicating the end of the transaction by the speaker of the handset, and/or by a message on the screen 5 or, by virtue of an acoustic and/or luminous signal of the apparatus, or else the transmission of data will be done, not in two consecutive phases, but in a single phase: in order to do this, it will be necessary for the data to be transmitted from the casing 1 to the computer and from the computer to the casing at the same time, by appropriately placing the microphone/speaker pair of the casing on that of the handset; in this case, it would be useful to vary the distance and the inclination of the microphone/speaker pair. This adjustment can be done by virtue of a linkage, or by any other type of well-known telescopic system. 
     After the user sees his flight confirmed by the computer, the parameters related to this flight will be memorized in the permanent chip of the card. Actually, for all the procedures that will follow, the casing will serve as a substitute for the traditional ticket, and all the elements of the chip may be consulted at any time, either by the passenger, or by any other authorized person or organization. From this moment onwards, the casing will enable the passenger to board the flight by virtue of an infrared interface. As shown in FIG. 8, and in fact, when the user has to pass through different gates or an access passage 20 in order to embark on the plane, a permanent specialized terminal 11 will emit an infrared signal, recognized by the portable casing 1 as an invitation to transmit the elements concerning the flight chosen and confirmed by the user during the acoustic transmission described previously. 
     The portable casing 1 will, in fact, dialogue with the terminal 11 in order to verify and validate the passage, if all is considered normal. After the transfer of data with the central computer, the terminal 11 will enable the passenger to pass through, in accordance with any procedure adopted by the airline: releasing a turnstile, emitting any type of acquiescence signal, etc. If there is an irregularity, the system will display its disagreement and will not allow passage. At all times, the casing will serve as the ticket, by displaying, when necessary, the particulars of the flight. Moreover, the permanent chip will memorize the flights of each user in order to enable the different advantages offered by the company to be applied to each case: a free ticket for X number of flights, according to such or such criteria, flight histories, etc. 
     Of course, these different elements must respect confidentiality laws and, to this effect, it would be possible, not to have access to the data except by virtue of a secret personal code. 
     According to another version, the apparatus may also serve as a means of payment. As illustrated in FIG. 5, in order to do this, it will be necessary to replace the chip card 2 in the card slot 10 of the portable casing 1 with a bank card 15 with chips, or with any other credit card, and in fact, the bank card 15 may have a recess that will enable it to receive the removable chip. A long distance payment will be done by virtue of an acoustic interface, similar to that of the data transfer, during the reservation phase described previously, whereby data is transmitted between speaker 8, microphone 9 and handset 12, and via a telephone line 22 to a computer center 18. The same telephone line 22 will also enable the memorized data to be reactualized in the removable chip. Another application of the system described in the present patent is the friendly communication between the portable systems described previously and any other device capable of dialoguing with the portable systems. 
     Three non-limiting embodiments of the use of the invention will be described hereafter: 
     1) PORTABLE/SYSTEM 
     2) PORTABLE/PORTABLE 
     3) PORTABLE/SYSTEM/PORTABLE OR INDIVIDUAL 
     The first embodiment mentioned above, is in fact, the case of airline reservation systems, seen above, but the PORTABLE/SYSTEM application of the most general type, will include, among others, mail orders. The clientele need only slide the optical scanner 7 on the reference(s) desired, lift the telephone off the hook and the transmission of data will be done automatically towards a specialized server or computer center 18 (as shown in FIG. 6B), which, on receiving the data, will interpret it and send the client an acknowledgment, a suggestion, etc. Of course, during the transmission of data, the casing took into account the individual parameters of each client, memorized in the chip card. 
     In a second embodiment, PORTABLE/PORTABLE, the data of a portable casing 1 are directly transmitted to another portable casing 1, either by virtue of their respective optical units 6 (as shown in FIG. 3) or acoustically (as shown in FIG. 4) by a telephone line, and in this case, the user will have to type a text or different data via the keyboard 4, or by any other means available on the portable and then the data will be received by another waiting portable, at the other end of the telephone line 22. In this case, the present system has the advantage of transmitting data rapidly and economically, especially, when the transmitting and receiving casings are separated geographically. 
     Finally, in the third embodiment of the system presented in the present patent, that is to say, a PORTABLE/SYSTEM/PORTABLE or the owner of a portable casing 1, the concept concerns a message center, especially for an inter-subscriber service via a server center adapted to this effect. Referring to FIG. 7, the subscriber who is qualified by virtue of the data memorized in the chip card 2 installed in his portable casing 1, can contact another interlocuter whose profile corresponds with a specific request, via a central server system 30. Example a user, subscribing to a &#34;Cinema lovers&#34; service, and arriving in an unknown town, who wishes to see the latest film of a particular director, can do so, in the company of a university student, fan of the same director, and wanting to see the same film. 
     The user will program all the elements relative to his wishes, by the keyboard 4, and by virtue of a friendly exchange authorized by the chip dedicated to a specific application. 
     Once the data has been entered, it is sent towards a server center 30 that will analyze the request and orient it towards another person, who has formulated a similar proposal Different interlocuters can come into contact with each other directly, in such a way, that the caller transmitting a definite proposal, can directly contact a corresponding person, who has himself, put forward a similar proposal earlier. 
     The server center 30 appropriately diverts the different parameters of the proposal after analyzing them (in our example): choice of film, time, geographical location, transport means, etc. Direct telephone contact basically respects the confidentiality of the parties concerned, because one party can never be in a position to know any information regarding the other, because the contact is established in a completely anonymous fashion. The server center 30 acts as a selective and intelligent call-diverting unit. The first person to call the server center 30 leaves the parameters of a specific proposal, as well as his telephone number. The next caller with a compatible proposal sees his call directly oriented towards the first person having made a similar request. Of course, this message center can have a simplified form, such as consultation of a database: stock exchange, sports results, weather, etc. The message center can be used either by a specific section of the population, having a memory chip card, or an interchangeable chip, dedicated to a specific use after having paid their dues; or, it can address a wider, less specific section of the population, such as subscribers to message centers of the &#34;MINITEL&#34; type. 
     We will now describe, as a non-limiting example, one special embodiment of the invention, with reference to the annexed drawings, wherein; 
     FIGS. 1A and 1B illustrate a portable casing according to the invention; 
     FIGS. 2A and 2B illustrate a portable casing of the present invention in transmission mode. 
     In FIGS. 1A and 1B, we have a casing (1) that has integrated processing means, controlled, for example, by a micro-processor and communication means. A keyboard (4) enables the user to manually enter the data; an infrared transmitter/receiver (6) enables dialogue with a terminal (11); an acoustic transmitter (8) and receiver (9) enables dialogue, via a telephone network, with any other system provided to this effect (server, databank, computer center, etc.). 
     An optical scanner (7) capable of reading specific codes such as bar codes and others. Any data inputted by the above-mentioned communication means can be displayed on a screen (5). 
     The portable casing includes a card slot (10) adapted to receive a card (2) comprising of one or several micro-circuits (3) and/or one or several memory supports (3). The most typical configuration being the following: 
     a permanent micro-circuit containing elements for the identification of the user; 
     an interchangeable micro-circuit containing a memory and enabling a specific use by the user, for example, a micro-circuit integrating plane time tables, the different shows in a city, etc., or, more broadly, a micro-circuit enabling access to a particular server center. 
     FIG. 2A depicts shows a portable casing (1) communicating with a specialized terminal (11) by virtue of their respective optical interfaces, and FIG. 2B illustrates a portable casing (1) communicating via a telephone receiver (12). 
     Other variations and modifications can, of course, be brought to this description, but these will neither be outside the scope, nor the spirit of the present invention.
