Abstract: An IC card transaction system is disclosed in which at least a portion of the data required to complete a transaction processing is stored in the card by a customer in advance of transaction processing. An automatic transaction processing unit reads the transaction data stored in the card, checks to determine what transaction data, if any, which is required for the processing of the transaction is not stored in the card and, if necessary, receives from the customer any additional data which was not previously stored in the card and which is required to complete a transaction.

Abstract: Method and apparatus for enabling fluid material contained in a package to be examined in a non-destructive manner to see whether there is any unacceptable alteration in the material. This examination is accomplished by shaking the package so that the package and its contents vibrate at the natural resonance frequency thereof, exposing the package to an irradiation of ultra-soft X-ray beams while the package is vibrating at the resonant frequency, either immediately after the package contents begin to be agitated by shaking or immediately after the vibration is stopped and it ceases to be agitated, detecting the strength of X-rays transmitted through the package and its contents, coverting the transmitted X-rays to a corresponding analog signal, and determining any alteration by comparing the analog signal against the refernece signal previously obtained in the same manner as described above for a like package with unaltered contents.

Abstract: An IC card transaction system is disclosed in which at least a portion of the data required to complete a transaction processing is stored in the card by a customer in advance of transaction processing.

Abstract: A voice recording card (1) can record and reproduce a message and when it is inserted into a transmitting and receiving apparatus (3), it can transmit and receive the message. In a recording mode, the message is applied through a microphone (14), converted into a digital signal by an analog/digital converter (21) and is recorded in a memory (22). In a transmission mode, the content of the message is read out from the memory (22) and is transmitted through an interface (24) to the transmitting and receiving apparatus (3). In a receiving mode, the content of the message received by the transmitting and receiving apparatus (3) is recorded in the memory (22) through the interface (24) and is read out, in a reproduction mode, from the memory (22) and converted into an analog signal by a digital-analog converter (23) to be outputted from a speaker (15).

Abstract: A deposit mode for inserting cash into an inserting opening for cash deposit and an envelope deposit mode for putting cash into an envelope and inserting the envelope into an opening for deposit are selectively set by a transaction mode setting unit. In the cash deposit mode, acceptance of cash inserted into the inserting opening for deposit is judged by a judgement unit. A deposit mode processing unit is provided to effect deposit processing for acceptable cash and to effect return processing for unacceptable cash which is not capable of being transacted, in accordance with the result of the judgement. An inquiry is made by a display unit to a depositor concerning whether or not returned money will be deposited in an envelope. In the envelope deposit mode, a request instructing unit instructs a client to input a value for an amount of cash to be placed into an envelope.

Abstract: A credit transaction processing system processes data related to a commodity entered into by using a card (17) owned by a customer and a recording card (16) owned by a store. First, merchant transaction data necessary for a credit sale stored in the recording medium (16), such as account number data for the store, data specifying a credit company, and data representing an upper limit of an amount to to be sold through a credit sale, are read by a card reader (5), and then, customer transaction data stored in the customer's recording card, such as account number data of the customer, data specifying a credit company and an identification number or code is read. If and when the customer enters his identification number by a ten-key (7), a central processing unit (12) determines whether the entered identification number coincides with the identification number read out of the customer's card.
