Patent attributes
A portable telephone including a transmission and reception unit, a control unit, a speaker, a display unit, a code reader unit, an operation input section, a microphone and a storage unit. The storage unit includes a telephone number memory, a password-data memory, and a personal-attribute memory. A buyer scans a code, in which product information is encoded, using the code reader unit, and enters password data via the operation input section. The control unit performs a comparison of the entered password data and password data previously stored in the password-data memory. After the comparison, the transmission and reception unit transmits via an antenna the product information, the telephone number stored in the telephone number memory, and personal-attribute data stored in the personal-attribute memory to a mobile telephone company. The transmitted information is used in settlement of the sales amount.
