When a portable telephone 5 is rented from a first rental shop 4-1 and returned to a second rental shop 4-2 different from the first, the telephone identification code 5(ID) and the first rental shop identification code 4-1(ID) stored therein are read and transmitted to a control center 2. Simultaneously, the number of call units 52A recorded in the portable telephone 5 is also read and transmitted to the control center 2. Based on this return data 20, the control center 2 is able to track the movement of the portable telephones 5 among the rental shops 4 (4-1, 4-2, . . . ) and to enter the use charge in the accounts as sales of the first rental shop 4-1.
