Detailed ways

The present invention will be described in further detail below with reference to the accompanying drawings and in combination with specific embodiments.

As shown in Figure 1, the POS terminal of the present invention mainly includes a microcontroller circuit, a keyboard circuit, a display circuit, a data storage circuit, a card reader, a fingerprint recognition circuit, a communication interface circuit and a communication cable/antenna. Among them, the microcontroller circuit is the core of the entire POS terminal, which is used for the management and scheduling of other circuits; the keyboard circuit and display circuit are used for the human-computer interaction between the POS terminal and the user. Through the keyboard circuit, the user can input information, The POS terminal displays the operation results to the user through the display circuit; the data storage circuit is used to store the management and transaction data of the POS terminal; the card reader is used to read the data of the user's magnetic card or IC card, and the fingerprint recognition circuit is used for Identify the user's fingerprint information; the communication interface circuit and communication cable/antenna are used to complete the communication function between the POS terminal and the outside world.

There are generally two ways to communicate with POS terminals: 1) Local connection. The POS terminal is equipped with a COM communication port, USB port or Ethernet port, etc., and is connected to the server end of the POS terminal through a communication cable, for example, it is equipped with a POS management system. The computer of the system; this method is reliable and fast, but requires a close connection to the server. 2) Remote connection, the POS terminal is connected to the remote server through telephone line, GPRS/GSM/CDMA wireless network, WAN, etc. This method is not limited by the location, and the communication can be completed in any place with network connection , but limited by the network transmission speed.

As shown in Figure 2, in this embodiment, the microcontroller circuit uses an ARM7 processor, which is connected to the fingerprint identification circuit through a UART interface, and has 4 control pins, which are data transmission, data reception, reset and power supply. The UART interface is a universal asynchronous transceiver interface, which generally provides the following functions:

Convert the parallel data transmitted from inside the computer into an output serial data stream. Converts serial data from outside the computer into bytes for use by devices that use parallel data inside the computer. Add parity bits to the output serial data stream, and perform parity check on the data stream received from the outside. Adds start and stop markers to the output data stream and removes start and stop markers from the receive data stream. Handling the interrupt signal sent by the keyboard or mouse can handle the synchronization management problem between the computer and the external serial device.

The fingerprint identification circuit collects the fingerprint image, and completes the matching detection process of the fingerprint through the microcontroller circuit. The matching fingerprint used for detection comes from the fingerprint information of the user's magnetic card or IC card, or the fingerprint database of the management center. By using this An identity authentication technology with personal characteristics can effectively prevent illegal use by unauthorized users.

The POS terminal of the utility model can ensure that the fingerprint data will not be exposed in a non-safe computer host environment through encrypted storage technology; during communication, the communication encryption technology is used to effectively protect the transmission between the POS terminal and the server. The data can implement different transaction schemes in various industrial fields. For example, in the banking and financial industries, signatures or PINs are traditionally used as user identity authentication during transactions, but using the POS terminal of the utility model, users can A unique fingerprint will be used as an authentication method during the transaction. A smart card can be given to confirm and identify the identity. During the identity authentication process, the POS terminal will perform corresponding matching processing between the fingerprint stored on the smart card and the cardholder's own fingerprint. In addition, it is also possible to connect the server-side database through GPRS/GSM/CDMA wireless connection or wired cable to match the cardholder's own fingerprint with the fingerprint sample stored in the database, so as to complete the online identity authentication .

It is also possible not to use a smart card during the entire operation, in which case each customer has a corresponding customer ID. During the transaction, the customer enters the corresponding customer ID, and the server finds the corresponding fingerprint in the fingerprint database through the customer ID and compares it with the fingerprint collected by the fingerprint scanning device of the POS terminal.

Similarly, in the retail industry, through the use of the POS terminal of the present utility model, the customer's finger can be used as a prepaid electronic wallet without cash or bank card, which improves the convenience of the user in the transaction.

The POS terminal of the present utility model can also be used for multiple purposes, such as online fingerprint checking: even if the employer leaves the shop or office, he can still monitor his employees. When an employee goes to work, he needs to put his finger on the POS terminal and scan the information as an attendance record. The information can be quickly transmitted to the server for updating through the wireless network, and the employer can view it online through the computer and monitor the employees at any time. Another example is that police officers or government officials can carry mobile fingerprint POS terminals to verify driver's licenses, passports and ID cards anytime, anywhere. This quickly detects fake documents, reduces fraud, and simplifies and speeds up the authentication process.

The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and it cannot be assumed that the specific implementation of the utility model is only limited to these descriptions. For a person of ordinary skill in the technical field to which the utility model belongs, without departing from the concept of the utility model, some simple deduction or substitutions can also be made, which should be regarded as belonging to the protection scope of the utility model.
