Abstract: PURPOSE: A system of supplying telebanking services is provided to prevent a credit account embezzlement by other telephone of other person, by using a fingerprint and a transaction telephone only of a customer to realize financial transactions for credit rights, and by identifying whether a telephone number and a fingerprint of a credit account are equal to the fingerprint and the telephone of the customer through a telephone number retrieval/security system and a fingerprint signal retrieving system, when the customer requests the financial transactions with the registered transaction telephone. CONSTITUTION: A telephone number of a transaction telephone(2) of a customer(1) and fingerprint data are supplied to a managing bank(10) as ID authentication signals connected to a credit account. The telephone number and the fingerprint data are electronically registered in a telephone number retrieval/security system(4) and a fingerprint signal retrieving system(5) connected to a telebanking system(3). When the customer wants financial transactions, the managing back is called through the transaction telephone. The managing bank is connected with the telebanking system, and the financial transactions are realized. The telebanking system identifies whether the telephone number registered in the credit account and a telephone number of a transmitter are equal. The fingerprint signal retrieving system authenticates whether a fingerprint signal registered in the credit account and a fingerprint signal suggested when the financial transactions are performed are equal, to approve the financial transactions. If the financial transactions are performed without any problems, self/other account transactions, customer terminal(8) transactions, automatic teller machine(9) transactions are performed. Calculating processes are performed in the self/other account transactions by a transaction manage system(6).

Filed: 2000-09-04
Abstract: PURPOSE: To provide a semiconductor device, with which the number of constitutive layers required for a multilayered substrate is reduced while keeping the location of solder bumps for signal to be connected to the electrodes of a semiconductor chip as conventional. CONSTITUTION: Since a signal line 12 of a first signal layer 9 is guided to a lower multilayered part via a through hole 15 selected on fixed conditions, even when a second signal layer 9 and the first signal layer 9 are overlapped without interposing a plane layer, a crosstalk noise does not become a problem. Besides, since a ground plane 14 is provided at the spot, where the signal line 12 is absent, of the first signal layer 9, even without providing the other plane layer between the first signal line 12 and the second signal layer 12, the second signal layer 12 can be made into strip structure held between planes. Thus, since one plane layer is unnecessitated, as a result, the number of layers required for the multilayered substrate can be reduced.
