FIG. 10 also shows a specific data format 301 of the received data 300. The received data 300 includes a start code 302, a basic code (code-related data) 304 as basic data following the start code 302, an additional information code (related- information code) 306 as related-information data including information related to the basic data following the basic code 304, and an end code 308 following the additional information code 306. As indicated by the specific data format 301, the start code 302 includes a start code 302a representing a synchronizing signal for reception, and the basic code 304 includes an article discount code 304a as code-related data which can be optically read. The article discount code 304a is indi- cated as a code or a number. The additional information code 306 includes article name data 306a representing the name of the article, article image data 306b representing the image of the article, article price data 306c representing the price of the article (discount price), and article message data 306d characterizing the article. The additional information code 306 comprises image information and/or audio information. Since the article image data 306b actually comprises a large amount data, it is transmitted as compressed data. The end code 308 includes a code representing the end of the received data 300 and a phase compensation signal, etc. FIG. 11 shows an article discount code 304ai which expresses the article discount code 304a (see FIG. 10) as a bar code and an article discount code 304an which expresses the article discount code 304a as a number, as an example of optically readable code-related data which is displayed as graphic data on the display screen 57 (referred to as "displayed image 57a" when it displays the codes shown in FIG. 11) of the display unit 58 of the portable information communication terminal 28. The article discount code 304an expressed as a number can be considered as optically readable code-related data. FIG. 12 is a flowchart of an operation sequence for converting the article discount code 304a of the basic code 304 of the received data 300 into optically readable data and displaying the data on the display screen 57 of the portable information communication terminal 28. When the portable information communication terminal 28 which is connected to the entertainment apparatus 102 as shown in FIG. 1 or which is used as a stand-alone device as shown in FIG. 2 is turned on and capable of receiving wireless signals, the CPU 224 intermittently or continuously confirms in step SI whether there is received data 301 in the wireless communication block 220 as a wireless signal receiver or not . If YES in step SI, i.e., if there is received data 301 in the wireless communication block 220, then the CPU 224 transfers the received data 301 to the working memory 226 in step S2. In step S3, the CPU 224 reads the basic code 304, i.e., the article discount code 304a, from the received data 301, and converts the article discount code 304a into bar code data as optically readable code-related data. At this time, the CPU 224 functions as a code data converter for converting basic code data received by the wireless communication block 220 into optically readable code-related data. Another code data converter may be employed which comprises a decoder in the wireless communication block 220 for converting the basic code data received by the wireless communication block 220 into optically readable code-related data. A converting algorithm may be any algorithm compatible with the reading system, i.e., the system combined with the POS terminal 14 having the code reader 210 which comprises a bar-code reader, and is not limited to any particular algorithm. In step S4, the CPU 224 transfers the optically readable code-related data, i.e., bar code data, to the LCDC 228, which displays the article discount code 304ai as a bar code in an upper area of the displayed image 57a on the display unit 58 shown in FIG. 11. In this manner, the CPU 224 and the LCDC 228, which jointly make up a display controller, display the article discount code 304ai as a optically readable bar code represented by the code-related data in the displayed image 57a on the display unit 58. In step S5, the CPU 224 and the LCDC 228 also display the article discount code 304an expressed as a number in a lower area of the displayed image 57a on the display unit 58 shown in FIG. 11. In the present embodiment, the article discount code 304an expressed as a number is displayed to let the user know the details of the article discount code 304ai as a bar code representation, and may not necessarily be required in the sales assistance system 10, 30 shown in FIGS. 1 and 2. While the article discount code 304ai in the form of a bar code representation is used as the article discount code 304a in the illustrated embodiment, the article discount code 304ai is not limited to a bar code representation, but may be expressed as a different code representation such as a number of dots or dots in different sizes. Therefore, an algorithm for converting the received data 301 into optically readable code-related data with the CPU 224 as a code data converter may be any algorithm compatible with the reading system, and is not required to be any particular algorithm specific to the code reader 210, which is a bar-code reader, of the CVS 13. FIG. 13 shows the contents of the additional information code (related-information data) 306 in the received data 300, 301 shown in FIG. 10, as displayed on the display screen 57 (referred to as "displayed image 57b" when it dis- plays the data shown in FIG. 13) of the portable information communication terminal 28. As described above, the additional information code (related-information data) 306 includes data corresponding to the details represented by the basic data (the article discount code 304a) of the basic code, and may be displayed on the display screen 57 of the display unit 58 when necessary or when the user operates the manual control pad 56 of the portable information communication terminal 28. In FIG. 13, the display screen 57 displays "sandwich" as an article name 306aa based on the article name data 306a in the received data shown in FIG. 11, a color image in perspective of a sandwich as an article image 306ba based on the article image data 306b in the form of photographic article data, "30 % OFF !" as discount information as an article message 306da based on the article message data 306d, and "¥280" as a discount price 306ca based on the article price data 306c. The Japanese expression may be replaced with another language expression such as an English expression. If the portable information communication terminal 28 is used in the United States, then the ¥ (yen) representation is replaced with a $ (dollar) representation. The displayed image 57a shown in FIG. 11 and the displayed image 57b shown in FIG. 13 may alternately be switched around by operating the manual control pad 56, or may simultaneously be displayed as split images. In this sense, the manual control pad 56 serves as an image selector switcher. FIG. 14 is a flowchart of an operation sequence for selecting the displayed images 57a, 57b based on instructions entered by the user. In step SH shown in FIG. 14, the processing in steps SI - S3 shown in FIG. FIG. 12 is carried out. Specifically, in step SI shown in FIG. 12, the CPU 224 intermittently or continuously confirms whether there is received data 301 in the wireless communication block 220 as a wireless signal receiver or not. If there is received data 301 in the wire- less communication block 220, then the CPU 224 transfers the received data 301 to the working memory 226 in step S2. In step S3, the CPU 224 reads the article discount code 304a from the received data 301, and converts the article discount code 304a into bar code data as optically readable code-related data. In step S12, the CPU 224 reads the article name data 306a, the article image data 306b, the article price data 306c, and the article message data 306d as related- information data from the received data 300, 301, and prepares for making these data ready for being displayed. In step S13, the CPU 224 confirms with the input block 234 whether there is data entered from the user via the manual control pad 56 or not. If there is data entered from the user via the manual control pad 56, the CPU 224 confirms in step S14 whether the entered data is an instruction for displaying the article discount code 304ai as a bar code with respect to a basic code (code-related data) or not. If the entered data is an instruction for displaying the article discount code 304ai, then the CPU 224 performs the processing in steps S4, S5 shown in FIG. 12 in step S15. Specifically, the CPU 224 transfers bar code data to the LCDC 228, which displays the article discount code 304ai as a bar code in the upper area of the displayed image 57a on the display unit 58 shown in FIG. 11. In step S5, the CPU 224 and the LCDC 228 also display the article discount code 304an expressed as a number in the lower area of the displayed image 57a (FIG. 11) together with the article discount code 304ai. If the entered data is not an instruction for displaying the article discount code 304ai, but an instruction for displaying an related-information image (additional information image) such as the article image 306ba, then the CPU 224 displays in step S16 the article name 306aa, the article image 306ba, the article message 306da, the discount price 306ca, and the article discount code 304an expressed as a number, in the displayed image 57b. Since the article image data 306b representing the article image 306ba is compressed data, the article image data 306b is expanded by the CPU 224 for displaying the article image 306ba in the displayed image 57b. By transmitting a relatively large amount of data such as image data as compressed data from the transmitting station 20, the transmitting station 20 can transmit images on a real-time basis using a pager system or the like which has a relative small data transfer rate. A process of processing a plurality of received data relative to different article discount codes will be described below. In this process, in order for the user to select an article discount code 304a to be displayed on the display screen 57 of the display unit 58, some additional information codes (related-information data) 306 of the received data 300 (301) are simultaneously displayed on the display screen 57 of the display unit 58. FIG. 15 shows four article images based on the article image data 306b of plural additional information codes (related-information data) 306, i.e., an article image 306ba of sandwich, an article image 306bb of wine, an article image 306bc of meat, and an article image 306bd of ice cream, displayed simultaneously in split images 57ca, 57cb, 57cc, 57cd, respectively, in the displayed image 57c on the dis- play unit 58. In the displayed image 57c, the article image 306bc of meat displayed in the split image 57cc having a background 310 in a different color shown as hatched in FIG. 15 and a thick image frame 312 represents a highlighted image selected by the user via the manual control pad 56. The highlighted image can be scrolled by the manual control pad 56. For example, when the user shifts the highlighted image to the split image 37ca showing the article image 306ba of sandwich, the displayed image changes to a displayed image 57d shown in FIG. 16 which contains the highlighted article image 306ba of sandwich in the split image 57ca which has a background 310 in a different color and a thick image frame 312. When the user operates the manual control pad 56 to decide on the article image 306ba, the displayed image changes to the image 57a showing the article discount code 304ai in the form of an article discount bar code corresponding to the article image 306ba of sandwich. When the user presents an article to be purchased and also the portable information communication terminal 28 which is displaying the article discount code 304ai in the form of an article discount bar code corresponding to the article to be purchased to the clerk in the CVS 13, the clerk reads the image 57a showing the article discount code 304ai with the code reader 210 (see FIGS. 1 and 2). The store computer 212 checks the article discount code 304ai against its own database. If the article discount code 304ai is not present in the database, then the store computer 212 checks a da- tabase in the central computer 16 at the CVS headquarters 15 on a real-time basis through the circuit network 26, and presents the article to the user at a discount price. The additional information code (related-information data) displayed as a character image on the display screen 57 may include an article discount period expressed as a range of days, and information designating discounting stores. These article discount period and discounting stores may also be displayed on the display screen 57. FIG. 17 is a flowchart of an operation sequence for se- lecting a desired one of additional information codes (related-information data) 306 displayed in FIG. 15 as the four article images 306ba, 306bb, 306bc, 306bd with a selecting instruction entered by the user via the manual control pad 56, and displaying the article discount code 304ai corre- sponding to the selected additional information code 306 in the displayed image 57a on the display unit 58 as shown in FIG. 11. In step S21 shown in FIG. 17, the processing in steps SI - S3 shown in FIG. FIG. 12 is carried out. Specifically, in step SI shown in FIG. 12, the CPU 224 intermittently or continuously confirms whether there is received data 301 in the wireless communication block 220 as a wireless signal receiver or not. If there is received data 301 in the wireless communication block 220, then the CPU 224 transfers the received data 301 to the working memory 226 in step S2. In step S3, the CPU 224 reads the article discount code 304a from the received data 301, and converts the article discount code 304a into bar code data as optically readable code-related data. In step S22, the CPU 224 determines whether there is any remaining received data 301 or not. In the example shown in FIG. 15, the processing in step S21 is further repeated three times. Stated otherwise, when the reception of four received data 301 relative to the four article images 306ba, 306bb, 306bc, 306bd is completed, control goes from step S22 to step S23. In step S23, the CPU 224 reads the additional information codes (related-information data) from the working memory 226, expands the additional information codes, and displays the image 57c shown in FIG. 15 on the display unit 58 via the LCDC 228. The displayed image 57c is comprised of the four split images 57ca, 57cb, 57σc, 57cd which display the article image 306ba of sandwich, the article image 306bb of wine, the article image 306bc of meat, and the article image 306bd of ice cream, respectively, based on the four received data 301. In step S24, the CPU 224 monitors the manual control pad 56 in the input block 234 for an instruction entered by the user. When an instruction is entered by the user, the CPU 224 confirms in step S25 whether the entered instruction represents a request for displaying a bar code in a selected image or not . If the entered instruction does not represent a request for displaying a bar code, then the CPU 224 confirms in step S27 whether the entered instruction is an instruction for scrolling the split images 57ca, 57cb, 57cc, 57cd in the displayed image 57c shown in FIG. 15 or not. If the entered instruction is a scrolling instruction, then the CPU 224 scrolls split images 57ca, 57cb, 57cc, 57cd, successively changing highlighted images in step S28. If the entered instruction is not a scrolling instruction in step S27, or if the scrolling process in step S28 is finished, then control goes back to step S24 to confirm whether there is an instruction entered by the user or not. If the entered instruction represents a request for displaying a bar code in step S25, then the CPU 224 displays the image 57a (see FIG. 11) including the article discount code 304ai expressed as a bar code which corresponds to the highlighted one of the split images 57ca, 57cb, 57cc, 57cd on the display unit 58. In this manner, the user can display the desired article discount code 304ai corresponding to a desired additional information code (related-information data) 306 selected from the additional information codes (related-information data) 306 (the four article images 306ba, 306bb, 306bc, 306bd in the example shown in FIG. 15) in the displayed im- age 57a on the display unit 58. According to another embodiment of the present invention, if the portable information communication terminal 28 has a uniquely identifiable individual identification code (so-called individual ID such as a hardware serial number or a production serial number) such as an identification code used by a portable telephone set, the individual identification code may be stored in the nonvolatile memory 222. If the individual identification code stored in the nonvolatile memory 222 can be read by the CPU 224, then the individual identification code may be displayed on the display screen 57 of the display unit 58 in the same representation as shown in FIG. 11, i.e., an optically readable graphic representation. According to still another embodiment of the present invention, it is assumed that the portable information communication terminal 28 stores a user identification code (user ID) in the nonvolatile memory 222. The user identification code may be manually entered and stored in the non- volatile memory 222 by the user when the user obtains, e.g., purchases, the portable information communication terminal 28. If the user identification code stored in the nonvolatile memory 222 can be read by the CPU 224 , then the user identification code may be displayed on the display screen 57 of the display unit 58 in the same representation as shown in FIG. 11, i.e., an optically readable graphic representation. FIG. 18 shows an example of the displayed image 57d which includes the article discount code 304ai expressed as a bar code relative to a particular code as a basic code and the article discount code 304an which expresses the article discount code as a number, and also includes an individual identification code 311 expressed as a bar code and an individual identification code 312 which is an alphabetic representation of the individual identification code 311. In the example shown in FIG. 18, the individual iden- tification code 311 and the individual identification code 312 may be replaced respectively with a user identification code expressed as a bar code and a user identification code which is representative of the name of the user. These user identification codes may be displayed together with the ar- tide discount code 304ai expressed as a bar code and the article discount code 304an expressed as a numerical representation. According to yet another embodiment of the present invention, in the example shown in FIG. 1 and the example shown in FIG. 6, when the portable information communication terminal 28 is connected to the entertainment apparatus 102 or when the portable information communication terminal 28 and the entertainment apparatus 102 are spaced from each other within a distance capable of infrared communications, the transmitting station 20 can transmit, to the portable information communication terminal 28, data 400 (401) which comprises, as shown in FIG. 19, a start code 302 (302a), a basic code (code-related data) 304 (304a) as basic data following the start code 302 (302a), and an end code 308 (308a) following the basic code 304 (304a), but not an additional information code (related-information data) 306, instead of the received data 300 (301) shown in FIG. 10. The data 400 (401) is received as received data 400 (401) by the portable information communication terminal 28. FIG. 19 is a flowchart of an operation sequence of the above embodiment in which the data 400 (401) is received as received data 400 (401) by the portable information communication terminal 28. In step S31 shown in FIG. 31, the CPU 224 of the portable information communication terminal 28 confirms whether there is received data 401 in the wireless communication block 220. If there is received data 401 in the wireless communication block 220, then the CPU 224 transfers the received data 401 to the working memory 226 in step S32. In step S33, the CPU 224 transfers the received data 401 to the entertainment apparatus 102 via the serial communication block 236 or the infrared communication block 238. In the entertainment apparatus 102, the CPU 252 confirms the transfer of the received data 401 in step S41, and then transfer the received data 401 to the main memory 258 in step S42. In step S43, the CPU 252 searches the optical disk 156 as a mass-storage medium and/or the main memory 258 for data using a key represented by the article discount code 304a as a basic code (code-related data) in the received data 401, reads related-information data as an additional information code corresponding to the article discount code 304a, and sends the related-information data from the main memory 258 via the graphic processor 260 to the display monitor 164. In step S44, the CPU 252 displays the same image as the image 57b shown in FIG. 13 at an enlarged scale on the display screen 201 of the display monitor 164. Specifically, the display screen 201 of the display monitor 164 displays "sandwich" as the article name 306aa based on the article name data 306a, a color image in perspective of a sandwich as the article image 306ba based on the article image data 306b, "30 % OFF !" as the article message 306da based on the article message data 306d, and "¥280" as the discount price 306ca based on the article price data 306c. In the portable information communication terminal 28, the CPU 224 executes step S34 after it has transmitted the received data 401 to the entertainment apparatus 102 in step S33. Specifically, the CPU 224 executes the processing in steps S3 - S5 shown in FIG. FIG. 12 in step S34. Specifically, in step S3 shown in FIG. 12, the CPU 224 reads the article discount code 304a from the received data 301, and converts the article discount code 304a into bar code data as optically readable code-related data. In step S4, the CPU 224 transfers the optically readable code-related data, i.e., bar code data, to the LCDC 228, which displays the article discount code 304ai as a bar code in the upper area of the displayed image 57a on the display unit 58 shown in FIG. 11. In step S5, the CPU 224 and the LCDC 228 also display the article discount code 304an expressed as a number in the lower area of the displayed image 57a on the display unit 58 shown in FIG. 11. In the embodiment described above with reference to the flowchart of FIG. 20, since no image data is contained in the data transmitted from the transmitting station 20, the transmitted data has a reduced amount of data. Since the related-information data employs data stored in the optical disk 156, a very fine, high-quality image can be displayed at an enlarge scale on the display screen 201 of the display monitor 164. FIG. 21 is a flowchart of an operation sequence of yet still another embodiment of the present invention. In this embodiment, in the example shown in FIG. 1 and the example shown in FIG. 6, when the portable information communication terminal 28 is connected to the entertainment apparatus 102 or when the portable information communication terminal 28 and the entertainment apparatus 102 are spaced from each other within a distance capable of infrared communications , the transmitting station 20 can transmit, to the portable information communication terminal 28, a plurality of data 401 each comprising, as shown in FIG. 19, a start code 302 (302a), a basic code (code-related data) 304 (304a), and an end code 308 (308a). The data 401 is received as a plurality received data 401 by the portable information communica- tion terminal 28. The entertainment apparatus 102 reads a plurality of items of related information corresponding to a plurality of received basic codes (code-related data) 304 (304a) from the optical disk 156 or the like, and displays the read items of related information on the display screen 201 of the display monitor 164. Based on an instruction entered from the manual controller 108, the entertainment apparatus 102 selects desired related information from the items of related infor- mation (see FIG. 6) displayed on the display screen 201 of the display monitor 164. Thereafter, the user enters, via the manual controller 108, an instruction to display a bar code relative to the basic code (particular code) corresponding to the selected related information. The corre- sponding code is now displayed on the display screen 57 of the display unit 58 of the portable information communication terminal 28. In steps S51 through S53 shown in FIG. 21, a plurality of received data 401 having different article discount codes 304a, as shown in FIG. 19, are received by the portable information communication terminal 28, and stored in the working memory 226. In step S54, the plural received data 401 are transferred to the entertainment apparatus 102 via the serial communication block 236 or the infrared communication block 238. If the CPU 252 of the entertainment apparatus 102 re- ceives the plural received data 401 in step S61, then the CPU 252 transfers the received data 401 to the main memory 258 in step S62. In step S63, the CPU 252 reads a plurality of related- information data corresponding to the different article discount codes 304a from the optical disk 156. Then, in step S64, the CPU 252 displays the same image as the image shown in FIG. 15 at an enlarged scale on the display screen 201 of the display monitor 164. In steps S65 through S69, the CPU 252 executes the same processing as the processing in steps S24 through S28 shown in FIG. 17 which has been described above with respect to the portable information communication terminal 28. Specifically, in step S65, the CPU 252 monitors the manual controller 108 in the input block 254 for an instruction entered by the user. When an instruction is entered by the user, the CPU 252 confirms in step S66 whether the entered instruction represents a request for displaying a bar code in a selected image or not. If the entered instruction does not represent a request for displaying a bar code, then the CPU 252 confirms in step S68 whether the entered instruction is an instruction for scrolling the split images 57ca, 57cb, 57cc, 57cd on the display screen 201 of the display monitor 164 as shown in FIG. 15 or not (see FIG. 6). If the entered instruction is a scrolling instruction, then the CPU 252 scrolls split images 57ca, 57cb, 57cc, 57cd, successively changes highlighted images in step S69. If the entered instruction is not a scrolling instruction in step S68, or if the scrolling process in step S69 is finished, then control goes back to step S65 to confirm whether there is an instruction entered by the user or not. If the entered instruction represents a request for displaying a bar code in step S66, then the CPU 252 transfers the request for displaying a bar code corresponding to the related information selected in step S67 via the serial communication block 250 to the portable information communi- cation terminal 28. The CPU 224 of the portable information communication terminal 28 which has received the request for displaying a bar code in step S55 displays the image 57a (see FIG. 11) including the article discount code 304ai expressed as a bar code corresponding to the highlighted one of the split images 57ca, 57σb, 57cc, 57cd on the display unit 58 in step S56. In the embodiment described above with reference to the flowchart of FIG. 21, since no image data is contained in the plural data transmitted from the transmitting station 20, the transmitted data has a highly reduced amount of data. Since the plural related-information data including a large amount of data such as image information employs data stored in the optical disk 156, very fine, high-quality im- ages can be displayed at an enlarge scale on the display screen 201 of the display monitor 164. Inasmuch as the user enters instructions via the manual controller 108, the user finds it easier and more efficient to enter instructions than via the manual control pad 56 of the portable information communication terminal 28. FIG. 22 is a flowchart of an operation sequence of a further embodiment of the present invention. In this embodiment, instead of receiving data as a wireless signal from the transmitting station 20 , the same data is sent from a mass-storage medium such as the optical disk 156, which serves as a software supply means for supplying software to the entertainment apparatus 102, to the portable information communication terminal 28. In step S71 shown in FIG. 22, the CPU 252 of the entertainment apparatus 102 reads data stored in the optical disk 156. In step S72, the CPU 252 determines whether the read data is data stored in the same pattern as the data 301 shown in FIG. 10 or not, i.e., whether the read data contains the data 301 including the article discount code 304a or not. If the read data contains the data 301, then the CPU 252 transfers the data via the serial communication block 250 to the portable information communication terminal 28 in step S73. The portable information communication terminal 28 then processes the data 301 in the same manner as with data received as a wireless signal. Therefore, the CPU 224 of the portable information communication terminal 28 carries out the same process as the process described above with reference to FIG. 12 in step S81. In step S81, the display screen 57 of the portable information communication terminal 28 displays the article discount code 304ai expressed as a bar code as shown in FIG. 11. The entertainment system described above with reference to the flowchart of FIG. 22 does not requires the antenna 218 and the wireless communication block 220 of the portable information communication terminal 28 and the infrastructure of the broadcasting system 24. However, the entertainment system described above with reference to the flowchart of FIG. 22 may employ the antenna 218, the wireless communication block 220, and the infrastructure of the broadcasting system 24. FIG. 23 is a flowchart of an operation sequence of an embodiment for downloading data relative to a plurality of different article discount codes from a mass-storage medium such as the optical disk 156, selecting desired related information with the manual controller 108 and displaying the selected related information on the display screen 201 of the display monitor 164, and displaying an optically readable code such as a bar code corresponding to the selected related information on the display screen 57 of the portable information communication terminal 28. In step S91 shown in FIG. 23, the CPU 252 of the enter- tainment apparatus 102 reads data stored in the optical disk 156. In step S92, the CPU 252 determines whether the read data is data stored in the same pattern as the data 301 shown in FIG. 10 or not, i.e., whether the read data contains the data 301 including the article discount code 304a or not. If the read data contains the data 301, then the CPU 252 transfers the data to the main memory 258 in step S93. Similarly, the CPU 252 searches for remaining data 301 in step S94, and then displays related-information data 301 corresponding to the different article discount codes 304a in the same pattern as in FIG. 15 on the display screen 201 of the display monitor 164 in step S95. Thereafter, the entertainment apparatus 102 carries out steps S96 through S100 which correspond to steps S65 through S69 shown in FIG. 21, and the portable information communication terminal 28 carries out steps Sill, S112 which correspond to steps S55, S56 shown in FIG. 21. After step S112, the display screen 57 of the display unit 58 of the portable information communication terminal 28 displays the article discount code 304ai as an optically readable bar code. In the examples shown in FIGS. 22 and 23, since the ba- sic data relative to particular codes stored in the optical disk 156 are displayed as the article discount code 304ai on the display screen 57 of the portable information communication terminal 28, the optical disk 156 as a mass-storage medium can indirectly be used as a substitute for the function of an article discount coupon. The above embodiments of the present invention offer the following various advantages : First , discount coupons which are usually distributed as printed matter can be distributed as wireless data by way of communications. Specifically, the portable information communication terminal 28 which has a function to receive wireless data transmitted intermittently and periodically converts received compressed data into optically readable data such as bar code data, and displays the converted data on the display screen 57 of the portable information communication terminal 28. Therefore, the user can take the re- ceived data with the portable information communication terminal 28 into the CVS 13 as a retail store. Secondly, since optically readable bar codes including the individual identification code 311 of the portable information communication terminal 28 and the user identifica- tion code peculiar to the user can be displayed on the display screen 57 of the portable information communication terminal 28, user information can automatically be entered into the POS system including the POS terminal 14 and the central computer 16, so that the CVS 13 can easily construct a customer database. Furthermore, a retail store such as the CVS 13 can distribute individual-oriented article information in a wireless manner based on the information including the user identification codes (individual identification codes) col- lected by the POS terminal 14. According to the present invention, as described above, a portable information communication terminal and an enter- tainment system which are easily capable of being combined with industrial systems can be constructed. Specifically, conventional portable information communication terminals cannot express received data as optically readable data and cannot be used for connection to industrial systems such as store automation systems. However, the portable information communication terminal according to the present invention is capable of expressing received data as optically readable data, and hence can easily be connected to an existing industrial system. The individual identification code of the portable information communication terminal and the user identification code can also automatically be entered into the existing industrial system. Conventional non-contact card systems usually output only predetermined codes, but do not offer a function to allow users to select codes such as of additional information. According to the present invention, however, the user can select codes. Heretofore, there has not been available any process of receiving part of information (basic information) in a wireless manner and receiving other additional information (related information) from a mass-storage package medium of a master unit such as an entertainment apparatus to which a portable information communication terminal is connected. According to the present invention, such additional information can be received from a mass-storage package medium. According to the present invention, therefore, there can be constructed a portable information communication terminal and an entertainment system which allow a portable information communication terminal capable of receiving wire- less signals and an entertainment apparatus to complement each other to create a new function. According to the present invention, moreover, there can be constructed a portable information communication terminal, an entertainment system, and a storage medium which are capable of increasing the convenience of a portable information communication terminal and an entertainment apparatus . The present invention can be applied to connection to not only retail stores such as convenience stores, but also industrial systems in networks such as kiosks in theme parks or the like, for an automatic exchange of information between article and service suppliers and customers using existing industrial systems . The portable information communication terminal is not limited to a portable information communication terminal that can be connected to an entertainment apparatus , but may be applied to personal computers , electronic notebooks , portable telephone sets, PHS terminals, pagers, etc. which have a personal computer a flat display unit such as a liquid crystal display (LCD) unit. Although certain preferred embodiments of the present invention have been shown and described in detail, it should be understood that various changes and modifications may be made therein without departing from the scope of the appended claims.
