The current RFID chip card structure design is easy for the unscrupulous person to illegally trigger the card reader to perform the stolen brush without the knowledge of the user.

In view of this, there is a manufacturer selling a ferrule that can block the charging magnetic field signal of the card reader, and can be placed outside the RFID chip card, but this design cannot fundamentally solve the problem that the current RFID chip card is easily stolen. The problem, and each time the RFID chip card is used, it is quite inconvenient to remove the RFID chip card from the card holder after the card holder is pulled out from the wallet or the bag.

And a power generating component embedded in the outer surface of the card body and connected to the signal emitting component, the power generating component sensitizing the power for driving the signal emitting component.

Therefore, the non-active charging type RFID chip module of the present invention comprises a signal transmitting component capable of being electrically driven to wirelessly transmit an RFID signal, and a signal connected to the signal emitting component and operable to generate the signal A power generating component that signals the power of the component.

Therefore, the non-active charging type RFID chip module of the present invention comprises a signal transmitting component capable of being electrically driven to wirelessly transmit an RFID signal, and a signal connected to the signal emitting component and capable of being photogenerated to drive the signal emission. Power generation component of the component's power.

The effect of the present invention is that the power generating component of the RFID chip module is designed such that the RFID chip card must be touched by the user or deliberately taken out of the sensor, so that the RFID signal can be sent for transaction identification. Solve the problem that traditional RFID chip cards have been easily stolen for a long time.

The invention will be further illustrated by the following examples, but it should be understood that this embodiment is for illustrative purposes only and is not to be construed as limiting The number is indicated.

Referring to Figures 1 and 2, the first embodiment of the non-active charging RFID chip card 3 of the present invention will only issue the RFID signal when held by the holder 800.

The RFID chip card 3 includes a card body 4 and an RFID chip module 5 that is fixedly mounted to the card body 4. The RFID chip module 5 has a signal transmitting component 51 that can be electrically driven to wirelessly transmit the RFID signal, and a power generating component 52 to which the signal is coupled to the signal emitting component 51.

In the present embodiment, the power generating element 52 is a piezoelectric element made of a piezoelectric material and capable of being pressed and deformed to generate electric power, for example, a piezoelectric wafer, which can be embedded in the card body 4 by being deformed by power generation. And the portion where the finger 801 is easily contacted when the card body 4 is held, for example, the long-term end portions, or the portion where the card body 4 is easily bent, for example, the long-direction intermediate portion, but not in the above position limit. The power generating element 52 is electrically driven by a single pressing deformation, and the signal transmitting element 51 can be driven to emit the RFID signal at a time.

Referring to Figures 2, 3 and 4, when the non-active charging type RFID chip card 3 of the present invention is used, since the RFID chip module 5 is not provided with a conventional charging coil, it cannot be illegally inductively charged by the lawless molecule by the card reader. Trigger for stealing. When the user 800 wants to use the RFID chip card 3 to perform an inductive payment transaction, the RFID chip card 3 needs to be held by the hand near the merchant card reader 900, and the power generating element 52 is pressed by operation (see FIG. 2). Or, by bending the card body 4 (as shown in FIG. 4), the power generating element 52 is driven to generate electric power. At this time, the signal transmitting element 51 is driven by the electric power generated by the power generating element 52. The RFID signal is sent for identification and transaction verification by the merchant card reader 900, and the power generated by the power generating component 52 is only enough to drive the signal transmitting component 51 to issue the RFID signal at a time, so the law is unlawful. The disciples could not illegally steal the card from the card reader.

The RFID chip module 5 cannot be automatically charged by the charging magnetic field of the card reader, but the holder 800 needs to operate the RFID chip card 3 to generate power to issue the RFID signal. The transaction of the RFID chip card 3 will be based on the will of the holder 800 itself, and the criminal cannot be illegally detected by other card readers, and it is not easy to drive the holder 800 without knowing it. The power generating component 52 is deformed to fundamentally improve the procrastination problem that has long existed in conventional RFID wafer card design.

In the present embodiment, the power generating element 52 is embedded in the card body 4. However, in other embodiments of the present invention, it can be designed to be embedded and exposed on the surface of the card body 4.

Referring to Figures 5 and 6, the second embodiment of the non-active charging RFID chip card 3 of the present invention differs from the first embodiment in the structural design of the power generating element 52. For convenience of description, in the following embodiments, only the differences between the present embodiment and the first embodiment will be described.

In the present embodiment, the card body 4 has a front surface 41 and a back surface 42 opposite to each other. The power generating component 52 is a thermoelectric component embedded in the card body 4 and made of a thermoelectric material, and has a first sensing portion 521 and a first portion that are opposite to each other and are adjacent to the front surface 41 and the back surface 42, respectively. Second sensing unit 522. The first sensing portion 521 can sense the temperature of the body surface of the front surface 41 to be heated, and the second sensing portion 522 can sense the body temperature of the body surface of the back surface 42 to increase the temperature, and the power generating element 52 will be the first When the temperature difference between the sensing portion 521 and the second sensing portion 522 reaches a power generation threshold, power for driving the signal transmitting element 51 to emit the RFID signal is generated. Since the power generation technology of the thermoelectric element is a conventional technique, and the structure type of the thermoelectric element is numerous, the structure of the power generation element 52 will not be described in detail.

When the consumer 800 wants to perform the inductive payment transaction with the RFID chip card 3, the RFID chip card 3 can be abutted against the merchant card reader 900, for example, the back side 42 is placed against the merchant card reader 900, and then The front surface 41 of the card body 4 that is in contact with the finger 801 corresponds to the area outside the first sensing portion 521, and the first sensing portion 521 is heated by the body surface temperature of the finger 801, thereby improving the first sensing portion 521. temperature. When the temperature difference between the first sensing portion 521 and the second sensing portion 522 reaches the power generation threshold, the power generating component 52 generates and outputs power sufficient to drive the signal transmitting component 51 to transmit the RFID signal.

When the transaction is completed, the finger 801 only needs to be moved away from the first sensing portion 521 to cool the first sensing portion 521, and the temperature difference between the first sensing portion 521 and the second sensing portion 522 is less than the power generation threshold. The power generating element 52 can be stopped from generating power, and the RFID chip card 3 stops transmitting the RFID signal.

Since the temperature difference between the first sensing portion 521 and the second sensing portion 522 that respectively drive the opposite faces of the card body 4 is driven to drive the power generating element 52 to generate electric power capable of driving the signal emitting element 51, the illegality is It is also impossible for the card reader to illegally detect the stolen brush from the side, and the first sensor unit 521 and the second sensor unit 522 are not able to generate a temperature difference sufficient for power generation without the knowledge of the holder 800. It fundamentally solves the problem that traditional RFID chip cards are easily stolen.

In this embodiment, the first sensing portion 521 and the second sensing portion 522 are embedded in the card body 4, and are respectively adjacent to the front surface 41 and the back surface 42, but when implemented, other in the present invention In an embodiment, the first sensing portion 521 and/or the second sensing portion 522 can be directly exposed on the surface of the card body 4 so as to directly contact the surface of the card body 4 for heating, thereby improving the heating speed. With heat dissipation speed.

Referring to Figures 7, 8, and 9, the third embodiment of the non-active charging type RFID wafer card 3 of the present invention differs from the first embodiment in the structural design of the power generating element 52.

In the present embodiment, the power generating element 52 is a photovoltaic element capable of converting light energy into electrical energy, such as a solar panel, and is embedded in the surface of the card body 4, and the RFID chip card 3 can be taken out in the light. In the environment, the light is generated to drive the signal transmitting component 51 to transmit the RFID signal.

When the RFID chip card 3 of the present invention is used, the holder 800 can take out the RFID chip card 3 and abut against the merchant card reader 900, and expose the power generating element 52 to sense ambient light, so that the power generating element The photosensitive light 52 generates sufficient power to drive the signal transmitting component 51 to emit the RFID signal. When the transaction is completed, the power generating element 52 can be shielded, and the power generating element 52 can be stopped from being photo-generated, so that the RFID chip card 3 can stop emitting the RFID signal.

Through the above design, it is also difficult for the criminals to provide the RFID chip card 3 with sufficient light to generate power for the power generating element 52 without the knowledge of the holder 800, so that the conventional RFID chip card can be fundamentally solved. The problem of stolen brush.

Referring to Figures 8 and 9, in practice, it is also possible to design light through the merchant card reader 900 to generate sufficient light to drive the power generating component 52 to generate power. For example, the RFID chip card 3 is stacked on the merchant card reader 900 with the power generating component 52 facing upward, and an illuminator 901 of the merchant card reader 900 is projected downward toward the power generating component 52 for a specific length of time. Light of a light intensity to drive the power generating element 52 generates sufficient power to drive the signal emitting element 51. Alternatively, the power generating component 52 of the RFID chip card 3 is placed face down on the merchant card reader 900, and then the illuminator 901 of the merchant card reader 900 is directly projected onto the power generating component 52 to drive light. The power generating element 52 is photo-generated to generate electric power. However, the implementation of the RFID chip card is not limited to the above manner.

In summary, the power generating component 52 of the RFID chip module 5 is designed such that when the RFID chip card 3 is used, it must be held by the holder 800 or deliberately taken out to generate the RFID signal for transaction. Identification, so it can be ensured that the use of the RFID chip card 3 is due to the will of the holder 800 itself, and since the conventional charging coil is not provided, the criminal cannot illegally steal the brush from the side by the card reader, which can be greatly Improving the security of the RFID chip card 3 and fundamentally solving the problems existing in the conventional RFID chip card 3 is a very innovative design of the RFID chip card 3. Therefore, the object of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the simple equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still Within the scope of the invention patent.
