PROBLEM TO BE SOLVED: To provide a safe electronic settlement method by using a portable terminal incorporating an electronic camera or an artificial retina chip. SOLUTION: Picture data transmitted from a portable terminal 30 to an authentication server 10 is subjected to character recognition by an internally provided picture recognition part, and the authentication server 10 transmits commodity information and personal information to a sale management server 23 after authenticating the portable terminal 30. In this case, a leased line 60 or the like is used as a transmission route so that access from the outside may be prohibited. Since a display picture of a display device 21 is transmitted as a picture signal from the portable terminal 30 to the authentication server 10, it is not intercepted even if a communication line of low security like the Internet is used. |
