BRIEF DESCRIPTION OF EXEMPLARY EMBODIMENTS Certain exemplary embodiments of the present invention will be described in greater detail with reference to the accompanying drawings. In the following description, same drawing reference numerals are used for the same elements even in different drawings. The matters defined in the description such as detailed construction and elements are provided only to assist in a comprehensive understanding of the invention. Thus, it is apparent that the present invention can be carried out without those defined matters. Also, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. The existing portable handset is used as an RFID transponder, but the portable handset according to an exemplary embodiment of the present invention has a function for an RFID reader, in addition to a function for the RFID transponder. Hereinafter, description will be made on the portable handset performing a function for the RFID transponder and a function for the RFID reader. FIG. 3 shows the portable handset performing a function for the RFID transponder. In FIG. 3, the portable handset has a server 300, a portable handset 320 as an RFID transponder, and an RFID reader 310. Hereinafter, description will be made on the portable handset as an RFID transponder with reference to FIG. 3. The RFID reader 310 continuously generates electromagnetic waves through the antenna. If the portable handset 320 enters a range in which it can receive the electromagnetic waves propagated from the RFID reader 310, the portable handset 320 receives the electromagnetic waves generated from the RFID reader 310. In order that the portable handset 320 receives the electromagnetic waves generated from the RFID reader 310, the portable handset 320 is provided with a function for receiving the electromagnetic waves. Description will be later made on a structure for the portable handset 320 to receive the electromagnetic waves generated from the RFID reader 310. If the portable handset 320 receives the electromagnetic waves of the RFID reader 310, the portable handset 320 sends response information with respect to the received information. For example, in case that the bus fare is paid by the portable handset 320, the RFID reader 310 installed in a bus makes an enquiry about whether the bus fare can be paid by the portable handset 320. The portable handset 320 having received the enquiry checks the amount of money or balance available for payment (the balance stored therein), and checks if the balance is more than the bus fare. If the balance is checked to be more than the bus fare, the portable handset 320 notifies that it can pay the bus fare, deducts the bus fare from the checked balance, and stores a new balance. The RFID reader 310 processes information received from the portable handset 320. In the above circumstance, the portable handset 320 holds therein information corresponding to a certain amount of money. However, in case of the current post-paid fare settlement system, the portable handset 320 can send its own information to the RFID reader 310. That is, the portable handset 320 can send the information of its unique number or user. The RFID reader 310, which has received the information of the unique number and user of the portable handset 320, sends the information to the server 300. The server 300 accumulates and stores the received information of the bus fares that the user of the portable handset 320 has to pay, using the received information. The accumulated bus fares are notified to the user of the portable handset 320 every period of time. FIG. 4 is a view for showing a portable handset serving as an RFID reader according to an exemplary embodiment of the present invention. FIG. 4 shows a server 400, a portable handset 410, and an RFID transponder 420. Hereinafter, description will be made in detail on the portable handset serving as the RFID reader with reference to FIG. 4. The portable handset 410 generates electromagnetic waves for the RFID according to the user's setting. In general, the portable handset 410 communicates with other portable handsets, or requests communications to a base station in order to read out data stored in the server 400. According to the user's setting, the portable handset 410 stops operations for communications with other portable handsets or for reading out data stored in the server 400, and serves only as the RFID reader. The portable handset 410 can perform operations for communications with other portable handsets or for reading out data stored in the server, and, at the same time, serve as the RFID reader. The RFID transponder 420, which has received the electromagnetic waves propagated from the portable handset 410, sends its stored information to the portable handset 410. The portable handset 410 that has received the information sent by the RFID transponder 420 can display the information on the display unit of the portable handset 410, or store the information in the storage unit of the portable handset 410. The stored information can be read out at any time upon requests of a user of the portable handset 410. If the user of the portable handset 410 needs information other than the information displayed on the display unit, the user can request the necessary information to the server 400 that stores the information. Description will be made on operations performed between the portable handset 410 and the server 400. If the RFID transponder 420 is a business card in which an RFID chip is embedded, the RFID transponder 420 sends information contained in the business card. The information contained in the business card may be a name, telephone numbers, business name, e-mail address, corporation homepage, and so on. If the user of the portable handset 410 that has received the information needs more information on the corporation in addition to the received information, the user requests necessary information to the server 400. The server 400 stores the business card and information on the business card. The server 400 sends to the portable handset 410 the stored information on the corporation upon the requests of the portable handset 410. Further, the portable handset 410 can connect to the corporation homepage contained in information it has received. Furthermore, the portable handset 410 can request communications at the received telephone numbers. If the RFID transponder 420 is a post in which the RFID chip is embedded, the RFID transponder 420 sends the information contained in the post. The information contained in the post may be movie titles, leading actors and actresses, release dates, and so on. If the user of the portable handset 410 which has received the information needs information other than the received information, the user requests necessary information to the server 400. The server 400 stores the post and the information on the post. The server 400 sends to the portable handset 410 the stored information on the post in response to the request of the portable handset 410. Further, the portable handset 410 can acquire necessary information through connections to the server 400. The information that can be stored in the server 400 may be information necessary for the user to understand the content of the movie, such as a preview of the movie, production processes, and so on. If the RFID transponder 420 is an item in which the RFID chip is embedded, the RFID transponder 420 sends information on the item. The information on the item may be a production place, producer, price, valid period of time, and so on, of the item. If the user of the portable handset 410 that has received the information needs more information other than the received information, the user requests necessary information to the server 400. The server 400 stores the information on the item. The server 400 sends to the portable handset 410 the stored information on the item upon requests of the portable handset 410. Further, the portable handset 410 can obtain necessary information through connections to the server 400. The information that can be stored in the server 400 may be producer's greetings, moving pictures for showing a cultivation process, distribution paths, and so on. Hereinafter, description will be made on a structure for signal receptions and transmissions of the portable handset having the RFID reader. The structure for signal receptions and transmissions of the portable handset may vary depending upon the frequency used for the RFID reader and the frequency used for mobile communications. If the frequency used for the RFID reader is identical to the frequency used for the mobile communications, the existing structure for signal receptions and transmissions can be used. If the frequency used for the RFID reader is not identical to the frequency used for the mobile communications, the existing structure for signal receptions and transmissions can be modified for use. Further, a structure serving as the RFID reader can be separately provided. First, description will be made on the case in which the frequency used for the RFID reader is identical to the frequency used for the mobile communications and the existing structure is used. FIG. 5 is a view for showing a structure for signal reception/transmission part of a portable handset having the RFID reader according to an exemplary embodiment of the present invention. As shown in FIG. 5, the portable handset has a signal transmission part and a signal reception part. The signal transmission part performs a function of the RFID reader and the existing function for mobile communications, at the same time. The signal reception part also performs the function of the RFID reader and the existing function for mobile communications, at the same time. The user of the portable handset sets the portable handset to the general mobile handset for communications or the RFID reader. The user can make such setting by manipulating a button provided on the portable handset or by using the options displayed on the portable handset. If the portable handset is set for mobile communications, the portable handset performs operations for the mobile communications, and, if the portable handset serves as the RFID reader, the portable handset performs operations of the RFID reader. The antenna 560 transmits and receives data and electromagnetic waves, and the directional coupler 550 sets the portable handset to the mobile handset for communications or the RFID reader. If the directional coupler 550 is used for the mobile communications, the band select filter (BSF) 518 to the mixer 500 and the mixer 520 to the band select filter (BSF) 544 perform the operations for mobile communications. If the directional coupler 550 is used as the RFID reader, the band select filter 518 to the mixer 500 and the mixer 520 to the band select filter 544 serve as the RFID reader. The same description as above is applied to the operations of the band select filter 518 to the mixer 500 and the mixer 520 to the band select filter 544. The description has been made so far on the operations performed in case that the frequency used for mobile communications is identical to the frequency used for the RFID reader. However, the portable handset can be used even in cases where the frequency used for the mobile communications is not identical to the frequency used for the RFID reader. In this case, the band select filter 518 to the mixer 500 and the mixer 520 to the band select filter 544 can operate differently. In general, the frequencies used for the RFID reader are different from those used for the mobile communications. Table 1 as below shows the frequencies used for the RFID reader and the frequencies used for the mobile communications. TABLE 1 Frequencies used RFID reader 850 MHz to 920 MHz or 2.4 GHz to 2.45 GHz GSM 850 MHz to 900 MHz or 1800 MHz to 1900 MHz CDMA 1850 MHz to 1910 MHz or 1930 MHz to 1990 MHz 824 MHz to 849 MHz or 869 MHz to 894 MHz W-CDMA 1920 MHz to 1980 MHz or 2110 MHz to 2179 MHz As shown in Table 1 as above, the frequencies used for the RFID reader are slightly different from those used for the mobile communications. Thus, if the portable handset of a single structure is used for the RFID reader and for general mobile communications, the structure has to operate differently for the two different functions. That is, different frequencies have to be generated from the local oscillators, filtered in various filters, and so on. The control signal controls the frequencies generated from the local oscillators and the frequencies filtered in the various filters. FIG. 6 is a view for showing a structure of a portable handset performing a function for mobile communications and a function for the RFID reader according to an exemplary embodiment of the present invention. In FIG. 6, the portable handset has a structure for carrying out the mobile communications and a structure carrying out a function for performing a function for the RFID reader, unlike those shown in FIG. 5. The structure performing the mobile communications has a mobile communication reception part 600 and a mobile communication transmission part 604, and the structure performing the function for the RFID reader also has an RFID reader reception part 602 and an RFID reader transmission part 606. The mobile communication reception part 600 and the RFID reader reception part 602 consist of the band select filter 518 to the mixer 500, and the mobile communication transmission part 604 and the RFID reader transmission part 606 consists of the mixer 520 to the band select filter 544. The descriptions on FIG. 1 and FIG. 2 can be applied to the operations that the band select filter 518 to the mixer 500 and the mixer 520 to the band select filter 544 carry out. The user of the portable handset sets the portable handset to a device for general mobile communications or an RFID reader. The user can set the portable handset as above by manipulating a button provided on the portable set or by using options displayed on the portable handset. If the portable handset is set for the mobile communications, the portable handset carries out operations for the mobile communications, and, if the portable handset is set for the RFID reader, the portable handset carries out operations for the RFID reader. If the portable handset is used for the mobile communications, the directional coupler 610 is connected to the mobile communication reception part 600 and the mobile communication transmission part 604, and, if the portable handset is used for the RFID reader, the directional coupler 610 is connected to the RFID reader reception part 602 and the RFID reader transmission part 606. In FIG. 6, the structure has a disadvantage of increasing the volume of the portable handset, but has an advantage of enabling the operations to be rapidly set for the structure of the RFID reader reception part 602 and the structure for the RFID reader transmission part 606. As stated above, the portable handset according to the present invention serves as the RFID reader enabling a built-in RFID chip to obtain information on business cards, posts, items, and so on. Further, if information is additionally required about the business cards, posts, and items, the portable handset connects to a server storing the information on the business cards, posts, and items, so that the user of the portable handset can obtain the desired information at any time. The foregoing embodiment and advantages are merely exemplary and are not to be construed as limiting the present invention. The present teaching can be readily applied to other types of apparatuses. Also, the description of the embodiments of the present invention is intended to be illustrative, and not to limit the scope of the claims, and many alternatives, modifications, and variations will be apparent to those skilled in the art.
