Mobile communication terminal and card information reading device

Abstract

A mobile communication terminal (the mobile station 100 ), served in a mobile communication network for performing wireless communications, comprises a transmitter-receiver 110, a controller 120, a user interface 130, a data input/output terminal 140, a magnetic writer 150, and a magnetic stripe 160. Control programs stored in a program ROM 122 include a program for controlling the magnetic writer such as writes or deletes various information into/from the magnetic stripe 160. In a credit card ROM 123 are stored information on the attributes of a credit card contract concluded in advance between a user and a credit card company. The magnetic writer 150 writes credit card contract information provided from the controller 120 to the magnetic stripe 160 or deletes the credit card contract information from the magnetic stripe 160.

 wherein said information required for electronic-commerce transactions are credit card information.    
     
     
         5 . A mobile communication terminal according to  claim 1 , 
 wherein said card information includes at least information for identifying a user.    
     
     
         6 . A mobile communication terminal according to  claim 1 , 
 wherein said output interface comprises: 
 a magnetic recording medium; and  
 a magnetic writer for reading out the card information selected by said selecting means from said memory to be written into said magnetic recording medium  
   
     
     
         7 . A mobile communication terminal according to  claim 6 , 
 wherein said magnetic recording medium is a card-type magnetic recording medium that can be read by a card reading device.    
     
     
         8 . A mobile communication terminal according to  claim 6 , 
 wherein said magnetic recording medium is provided within said mobile communication terminal, said magnetic recording medium being retracted inside said mobile communication terminal or being protruded out of said mobile communication terminal by a predetermined operation on said mobile communication terminal.    
     
     
         9 . A mobile communication terminal according to  claim 8 , 
 said magnetic writer, when the magnetic recording medium protruded out of said mobile communication terminal is retracted inside said mobile communication terminal, deletes the card information written in said magnetic recording medium.    
     
     
         10 . A mobile communication terminal according to  claim 1 , 
 wherein said output interface comprises 
 a code displaying device for displaying code that corresponds to card information read out from said memory, the code being optically readable.  
   
     
     
         11 . A mobile communication terminal according to  claim 1 , 
 wherein said output interface is    an infrared interface for emitting infrared rays designating card information read out from said memory.    
     
     
         12 . A mobile communication terminal according to  claim 1 , 
 wherein said output interface comprises: 
 a data input/output terminal for performing data input/output with an external device; and  
 a data reading device for providing card information read out from said memory with said data input/output terminal.  
   
     
     
         13 . A mobile communication terminal according to  claim 1 , 
 wherein said mobile communication terminal is a mobile telephone for performing wireless telephone communications.    
     
     
         14 . A mobile communication terminal, comprising 
 transmitting means for performing wireless communications with others through a mobile communication network; and    a magnetic recording medium for storing a plurality of card information items.
