In one embodiment, the reading unit 140 is implemented using an NFC antenna module.

The invention integrates the reading unit 140 and the touchpad 130 for cardholder authentication and account information transmission. In actual application, in order to reduce the overall device area, the reading unit 140 and the touch panel 130 are overlapped. Generally, the touch panel 130 has a touch surface 251 and an assembly surface 252. The touch surface 251 allows the user to perform a touch action on the finger or the object. The assembly surface 252 is correspondingly laid with a shield. Formation 220. In the case where the reading unit 140 and the touch panel 130 of the present invention are arranged in an overlapping manner, if it is desired to allow the wireless communication card 210a/210b to be read by the reading unit 140 at a position adjacent to the touch surface 251 (in the wireless communication area 140a) It is read that the radiation direction of the reading unit 140 must be upward (ie, the direction toward the touch surface 251). The signal sent from the reading unit 140 can be radiated from the gap between the lines of the touch panel 130 and is not shielded by the ground layer. The shielding ground layer 220 can not be laid between the reading unit 140 and the touch panel 130. Of course, the shielding ground layer 220 can still be laid on the non-overlapping portion of the reading unit 140 and the touch panel 130, such as the 2a. And 2b shown. In an embodiment, as shown in FIG. 2c, the reading unit 140 and the touch panel 130 are still overlapped, but the radiation direction of the reading unit 140 is downward (ie, toward the outside of the touch panel module, or In the opposite direction of the touch surface 251, in other words, the signal from the reading unit 140 is not shielded by the shield ground layer 220, the shield surface assembly surface 252 still has a shield ground layer 220.

In the following embodiments and drawings, the reading unit 140 and the touch panel 130 are disposed in an overlapping manner, and the direction in which the antenna radiation direction is directed toward the touch surface 251 (as shown in FIG. 2b) is taken as an example.

Returning to FIG. 1 , when the user terminal 180 needs to read the wireless communication card 210a/210b, a startup card reading command is transmitted to the touch panel control unit 110 and the communication control unit 150 through the communication interface 120 to activate the related control function. And card reading function. The communication interface 120 can transfer data, messages or commands between the authentication device 100 and a client 180 by using a wired or wireless method. The wired interface supported by the communication interface 120 is, for example, but not limited to, an interface such as USB and RS232, and the wireless interface supported by the communication interface 120 is, for example but not limited to, an interface such as Bluetooth and Wireless High Fidelity (Wi-Fi).

The encrypted card data in the encrypted wireless communication card 210a is transmitted from the reading unit 140 to the communication control unit 150 and temporarily stored in a storage unit 170. After receiving the encrypted card data, the communication control unit 150 sends a successful card reading message to the touch panel control unit 110. The touch panel control unit 110 transmits a generated input decryption information (password or signature) through the communication interface 120. The interface message is sent to the client 180, so that the client 180 generates an interface for inputting decryption information (password or signature), for example, causing the screen 180a of the client 180 to generate a window for inputting decryption information (password or signature), such as the third. As shown in the figure, the authentication device 100 and the client 180 then wait for the user to sequentially input decryption information (password or pattern).

According to the present invention, if the user needs to input a set of passwords, the touch panel 130 can be input through the following manner: a single finger can be used to perform handwritten numerals, symbols, or in the touch panel 130 (overlap with the wireless communication area 140a). The text is as shown in FIG. 4a; or, the virtual keyboard on the touchpad 130 can be clicked with a single finger or multiple fingers, as shown in FIG. 4b; or one or more fingers can be used on the touchpad 130.

Please note that this message is not a password, but a fixed profile. Whenever the user successfully enters a password/signature, a symbol (such as but not limited to "*") is displayed in the window of the screen 180a, and the real password input by the user is not displayed, so as to prevent the password from being leaked. Or be recorded by a Trojan horse. As in the example of Figure 3, the user has successfully entered two passwords/signatures. In addition, please note that during the password input process, because the candidate word cannot be displayed through the user terminal 180, only one identification mode can be selected for a group of passwords, such as but not limited to the digital identification mode, the symbol recognition mode, the character recognition mode, and the virtual keyboard identification. Mode, gesture recognition mode, etc., to improve the success rate of recognition.

In an embodiment, after receiving the encrypted card data in the card 210a, the communication control unit 150 extracts the specific converted password table of the plurality of converted password tables pre-stored by the firmware of the communication control unit 150 according to the value of n according to the decryption conversion method. n, decrypt the encrypted card data to restore an encrypted information and an account information, and then wait for the user to input a decryption information, and compare the two encryption/decryption information, if the two encryption/decryption information match The account information is transmitted to the server unit 190 through the communication interface 120 and the client terminal 180; if the two-digit encryption/decryption information does not match, the account information is blocked.

In another embodiment, after receiving the encrypted card data in the card 210a, the communication control unit 150 waits for the user to input a decryption message. After receiving the decryption information input by the user, according to the decryption key method, the communication control unit 150 decrypts the encrypted card data according to a decryption algorithm to restore account information, and performs data verification or check on the restored account information. For example, but not limited to, CRC verification to obtain a verification result value. Finally, it is determined whether the decryption information input by the user is correct according to whether the verification result value is equal to a preset value. If the user enters the decryption information correctly, the account information will be The communication unit 120 is transmitted to the servo unit 190 through the communication interface 120 and the user terminal 180; if not, the account information is blocked.
