FIG. 8 shows a sequence from insertion of a credit card through center processing to issuance of a slip, and FIG. 9 shows a password input process using the PIN pad 7, which is performed in an interrupt process.

When the digital card is inserted into the card reader 7, the information recorded on the card is read and (n20)
'Turn on the N certificate interrupt permission flag M6 (n2]). By turning on the password interruption permission flag M6, the interruption of password input shown in FIG. 9 is permitted. After reading the card, on the terminal body 1 side, the operator operates the keyboard 2 to input data related to the transaction (n22).
~ n26), and input of payment method (n27) is performed. In this example, assume that the sales key is pressed for a sales transaction and that a lump sum payment is instructed.゛In parallel to the input using the keyboard 2 described above, the PIN number input by the customer using the PIN pad 7 is accepted (n40, n41). This is done in the embedding process. The PIN data entered using the numeric keypad on prN pad 7 is stored in the buffer sequentially, and the PIN
By pressing the setting key on the N pad 7, the password input completion flag M5 is turned on and the password input is completed (n41 to n4
4). If the PIN code power is completed, the PIN code interruption permission flag M6
Turn off (n45). The above-mentioned password input is permitted only when the password interrupt permission flag M6 is on, so even if the PIN pad 7 is operated by mistake before the card is inserted, the entered number data becomes invalid, and erroneous operation can be prevented.

After completing the input operations (n22 to n27) on the terminal main unit 1 side and pressing the execution key to instruct data transmission (n
2B), at n29, it is determined whether or not the password input has been completed.

This determination is made by checking whether the password input completion flag M5 is on or off. That is, when the PIN entry completion flag M5 is off, it waits for the customer to input the 26 PIN number, and when it is on, it connects the line with the center and performs data transmission with the center (n
30. n31). Verify the PIN and register the sales data at the center TtVI (n32). If the PIN matches, the transaction processing result is received and the received data is output to the display unit 18° printer to complete the transaction. Displays the completion of processing and issues a sales slip (n 33). Also, if the password number does not match, an error message will be displayed on the display section 1.
Displayed by 8. After the ear removal process is completed, disconnect the line with the center and clear the RAM 12 to end the process (
n34. n35).

In this way, the input from the PTN pad 7 is accepted simultaneously with the manual key opening on the keyboard 2, and the input of the password is accepted by interrupt processing. As a result, the password can be entered at any time without being restricted by the transaction processing sequence, improving operability, reducing the time required for manual key operation on the terminal side, and further improving processing efficiency.

([) Invention No. 1] Result p) According to this invention, it is possible to input a password to a terminal device simultaneously with the keyboard of one terminal device With this in mind, we can interrupt manual PIN processing, allowing customers to freely ask for their PIN without being constrained by the PIN processing sequence.
Is it possible to input 1-1? The manual operation time of the φ key is shortened and the γ processing rate can be improved.Also, only when the flag indicating whether or not PIN input is permitted is on, an interrupt can be entered. Since the operation is done, the keys 16 and 19 are entered manually by the keypad before the start of the take 1. ;l'
This prevents erroneous operation and allows accurate witnessing.
