  In today's society, a large amount of currency transactions have already been digitized, and in addition to credit cards, various small payment methods such as electronic wallets, point cards, easy cards, etc. are used so that when users go out, they do not have any change. In addition to boarding public transport, you can also shop at various shops. You can also save cash bonus points, earn points in campaigns, or save electronic receipts via a chip, making it even more convenient and offsetting directly with cash consumption, It can be used regardless of Taiwan or foreign stores through the connection.

  However, the IC card is convenient in use, but it is easy to cause problems such as skimming or losing your name to others when it is lost. For authorization transactions ("authorization" is an abbreviation for "authorization", the same applies in this application), an online random password is sent to the user's mobile phone, and then the random password is entered, which is used as a transaction authorization key. Transaction approval for persons other than the user himself / herself (hereinafter referred to as “non-user himself / herself”) is prevented. There are also companies that provide IC cards with a built-in fingerprint authentication function. In this case, only when the user is identified by fingerprint recognition, the chip can be authorized to perform transactions.

  However, IC cards with a built-in fingerprint authentication function also have drawbacks. When the user's hand is too wet or the hand temperature is too low, the fingerprint cannot be read or the reading accuracy is affected. In addition, a problem has been pointed out that even if it is not the user himself / herself, it is erroneously determined as the user himself / herself with a probability of 1 / 100,000. Therefore, it was necessary to improve the reading accuracy.

  Referring to FIGS. 1 and 2, there are a three-dimensional exploded view and a block diagram of an IC card incorporating a fingerprint authentication function according to a first embodiment of the present invention. As shown in the figure, the IC card incorporating the fingerprint authentication function of the present invention includes a circuit board 1 and a battery unit 2.

  The circuit board 1 is provided with a fingerprint recognition module 11, a microprocessor 12 and a chip module 13. The circuit board 1 is used as a base material on which the fingerprint recognition module 11, the microprocessor 12, and the chip module 13 are placed, and the fingerprint recognition module 11, the microprocessor 12, and the chip module 13 are used in a plurality of times. Electrical connection is made through the route pattern 14, and the circuit line pattern 14 is printed on at least one side or both sides of the circuit board 1. The fingerprint recognition module 11 includes a first fingerprint recognition chip 111 and a second fingerprint recognition chip 112 in order to improve the recognition accuracy. The first and second fingerprint recognition chips 111 and 112 are provided adjacent to each other in the illustrated embodiment, and are used for gripping and fingerprint recognition in an ergonomic manner for the user.

  The battery unit 2 is electrically connected to the circuit board 1 and used to supply power to the circuit board 1. Since the first and second fingerprint recognition chips 111 and 112 and the microprocessor 12 are driven by electric power to perform fingerprint recognition and interpretation, the battery unit 2 can supply power necessary for them.

  The surface of the circuit board 1 of this embodiment can protect the microprocessor 12, their circuit line pattern 14, and the battery unit 2 by applying a protective film 5. The protective film or the seal does not cover a portion where the chip module 13 and the fingerprint recognition module 11 are provided.

  Referring to FIG. 3, it is a three-dimensional view of an IC card incorporating a fingerprint authentication function according to a second embodiment of the present invention. As shown in the figure, a part of the structure of this embodiment is the same as that of the first embodiment, and the description thereof is omitted here. However, the difference between the present embodiment and the first embodiment is the chip module. 13 is further provided with a sensoring antenna 4 that is electrically connected to the sensor 13 and that senses an external signal and transmits link data to at least one external device (not shown). The sensoring antenna 4 is printed on the circuit board 1 and senses the external device with each other using an identification technology (RFID: radio frequency identifier) using wireless communication.

  Referring to FIG. 4, it is a cross-sectional view of an IC card incorporating a fingerprint authentication function according to a third embodiment of the present invention. As shown in the figure, the partial structure of the present embodiment is the same as that of the first embodiment, and therefore the description thereof is omitted here. The difference between the present embodiment and the first embodiment is that the fingerprint is The recognition module 11 includes a first fingerprint recognition chip 111 and a second fingerprint recognition chip 112, and the first and second fingerprint recognition chips 111 and 112 are provided on both upper and lower sides of the circuit board 1.

  Referring to FIG. 5, it is a three-dimensional view of an IC card incorporating a fingerprint authentication function according to a fourth embodiment of the present invention. As shown in the figure, the partial structure of the present embodiment is the same as that of the first embodiment, and therefore the description thereof is omitted here. However, the difference between the present embodiment and the first embodiment is the casing 3. Is further provided. The casing 3 includes a housing space 31 and a plurality of through holes 32 communicating with the housing space 31, and the circuit board 1 and the battery unit 2 are housed in the housing space 31. The module 13 and the fingerprint recognition module 11 are exposed by corresponding to the position of the through hole 32.

  In the present invention, when fingerprint recognition is performed mainly through a user's finger, the first and second fingerprint recognition chips 111 and 112 simultaneously perform fingerprint recognition work, and then further transmit the recognized data to the microprocessor 12 for interpretation. When the data is read through the microprocessor 12 as being identical to the user's fingerprint data (the fingerprint recognition data must match the data sensed by the first and second fingerprint recognition chips 111 and 112 at the same time) The processor 12 can send another signal to the chip module 13 and authorize the chip module 13 to perform a transaction.

  The chip module 13 of the present invention can perform transactions by sensing each other with the external device through identification technology (RFID) using wireless communication, or directly contact the external device through the chip module 13 and electrically Connect and conduct transactions.

  The fingerprint recognition module 11 of the IC card incorporating the fingerprint authentication function of the present invention includes first and second fingerprint recognition chips 111 and 112, and is recognized by using these two sets of first and second fingerprint recognition chips 111 and 112. The accuracy can be improved. Since the conventional fingerprint recognition chip has only one set of fingerprint recognition chips, misjudgment easily occurs, and it was judged that the recognition was easily succeeded when the fingerprint recognition operation was repeated many times. In this case, the fingerprint recognition accuracy is lowered, and the security of the authorization is significantly lowered. In the present invention, mainly by providing the first and second fingerprint recognition chips 111 and 112, two sets of different fingerprint recognition data are provided, and after the two sets of fingerprint recognition data coincide with each other at the same time, the IC card is passed through the microprocessor 12. Since it is possible to authorize transactions and the interpretation data of the two fingerprint recognition chips must always match at the same time, it is difficult to determine that they succeeded by repeatedly trying with random numbers, and the fingerprint recognition data However, since the recognition accuracy is relatively higher than that of a set of conventional fingerprint recognition chips, the safety of IC card transactions can be greatly improved.
