[0058] S5: the camera module collects the barcode image frame sequence and pushes it into the POS terminal soft decoding library for decoding, and obtains the payment two-dimensional code data;

[0059] S6: the host POS terminal obtains the payment of the two-dimensional code data, and the networked background payment system completes the checksum payment; [0060] The present invention will change the operator body of the sweep code payment, and the operator only needs to operate the POS terminal. The action of sweeping the barcode is given to the customer to complete the initiative.

[0061] Specifically, the present invention implements communication between the POS terminal and the PINPAD PIN pad by using the USB as an interface.

[0062] The scanning code camera can be placed in the position shown in FIG. 1, that is, placed under the front of the PINPAD PIN pad, that is, below the liquid crystal display, and the position of the scanning code camera can be adjusted accordingly according to requirements.

2 is a block diagram of a PINPAD PIN pad system with a camera function according to an embodiment of the present invention. As shown in FIG. 2, the system of the present invention includes a POS terminal and a PINPAD PIN pad, wherein:

[0064] The POS terminal is provided with a communication command of a PINPAD PIN pad for extending the payment function of the bar code module.

[0065] The PINPAD password keyboard is provided with a camera module, and the camera module is composed of a CMOS camera with more than 300,000 pixels and an LED fill light, so that the camera module has a self-filling function, which can satisfy both the mobile phone and the paper. Scan code requirements for barcodes. When the POS terminal starts the camera module by the PINPAD command, the scan camera will collect the barcode image frame sequence and push it to the soft decoding library of the POS terminal for decoding.

[0066] The system of the present invention further provides a scan code payment scheme of the system as described above: The host POS terminal application selects according to the transaction of the client, including payment methods such as swiping, NFC, and bar code, and selects a bar code payment method. The POS terminal activates the camera module through the PINPAD command, the PINPAD LCD displays the payment amount, and prompts the user to open the QR code payment interface of the mobile phone (WeChat or Alipay). Thereafter, the user points the mobile phone screen to the PINPAD bar code camera. The camera module captures the barcode image frame sequence and sends it to the soft decoding library of the POS terminal for decoding by the USB. After the host POS terminal obtains the payment of the two-dimensional code data, the network background payment system completes the checksum payment. [0067] In particular, the POS terminal soft decoding library in the system of the present invention may use free decoding software such as Zbar or other third-party authorized decoding software, or may be independently developed, and thus is not limited to the prototype of the software, and is a person skilled in the art. Some modifications and optimizations can be made on this basis.
