Transaction safety system for falsely indicating successful completion of illegal transaction
First Claim
1. A transaction safety system in a data processing system which includes a transaction device, having an input portion and an output portion for providing a transaction result according to transaction data supplied by the input portion, operatively connected to a processing device, having a client file, for processing the transaction data received by the transaction device, the processing device operatively connected to a monitoring device, geographically separated from the transaction device, for monitoring transactions of the transaction device, said transaction safety system comprising:
- alarm signal sending means, provided in the transaction device, for sending an alarm signal when the transaction data received by the transaction device includes a special code;
file control means, operatively connected to said alarm signal sending means, for preventing update of the client file when the alarm signal is received by the processing device;
result sending means for sending the transaction result to the transaction device in dependence upon the transaction data supplied by the input portion regardless whether the transaction data includes the special code and for sending the alarm signal to the monitoring means; and
controlling means, operatively connected to said alarm signal sending means, for driving said alarm signal sending means when the special code is input on the input portion.

Abstract
A transaction device, having an input portion, and a processing device, having a client file, which is located at a processing center, are connected by a telephone line for processing data input on the transaction device. The transaction device sends an alarm signal when a transaction is carried out under duress via the transaction device. The updating of the client file is prevented when the alarm signal is received at the processing center and a false funds received processing text is sent to the transation device indicating that the client file was updated.

4. A transaction safety system in a data processing system which includes a transaction device, having an input portion and operatively connected to a processing device, the processing device having a client file and processing transaction data input via the transaction device, said transaction safety system comprising:
-
alarm signal sending means for sending an alarm signal when the transaction data input via the transaction device includes a special code; file control means, operatively connected to said alarm signal sending means, for preventing update of the client file when the alarm signal is received by the processing device; controlling means, operatively connected to said alarm signal sending means, for driving said alarm signal sending means when the special code is input via the input portion; buffer means, provided in the transaction device and operatively connected to said controlling means and the input portion, for temporarily storing the transaction data input via the input portion; and sending means, provided in the transaction device and operatively connected to said alarm signal sending means, said buffer means and connectable to the processing device, for sending the transaction data stored in said buffer means when the transaction data for a transaction is completely input, said controlling means storing the alarm signal in said buffer means when the special code is input, the alarm signal being sent together with the transaction data stored in said buffer means to the processing device by said sending means.

8. A transaction safety system, comprising:
-
a transaction device, comprising; an input portion for inputting input data regarding a transaction; an output portion for outputting text concerning the transaction; a distinguishing portion, operatively connected to said input portion, for detecting whether the input data includes a special code; and sending means, operatively connected to said distinguishing portion, for sending an alarm signal when said distinguishing portion detects the special code; and a processing device having a client file, operatively connectable to said sending means, comprising; alarm generating means, operatively connectable to said sending means, for generating an alarm when the alarm signal is received from said transaction device; and text sending means, operatively connected to said alarm generating means and connectable to said output portion, for sending the text concerning the transaction to said transaction device, the text appearing to represent a normal transaction when the alarm signal is generated by said transaction device even though the client file is not updated. - View Dependent Claims (9, 10, 11)
