PURPOSE: A terminal program linked with point of sale (POS) is provided to prevent the possibility of information hacking and leakage when the POS with no security module authorizes a credit card, thereby preventing the replication and unauthorized use of cards. CONSTITUTION: If users push early a specific key on the keyboard during the execution of a terminal program, the POS reads the number at a position designated on the screen of the POS and transmits the read number to a credit card terminal through the computer of the POS such that the payment of the credit card is performed. |
