Description

The present invention relates to a wireless inductive device and a wireless inductive device having a fingerprint identification function.

Wireless inductive devices typically use radio frequency identification (RFID) technology and include induction coils and chips, which are electrically connected to the induction coil. When the wireless inductive device approaches the inductive reader and when an alternating magnetic field emanating from the inductive reader is detected, the induction coil generates an electric current to supply to the chip by the action of electromagnetic induction, and further. The chip transmits the data to the induction reader based on the data stored inside the chip. This allows the inductive reader to identify the wireless inductive device based on the data.

Conventional wireless inductive devices are often used for access control and personnel identification in places such as companies and schools. For example, the wireless inductive device owned by each employee can store different employee data, and the enterprise inductive reader receives the employee data transmitted from the wireless inductive device and receives the employee data. Identifies the employee's identity (ID) based on.

However, conventional wireless inductive devices only provide the inductive reader with pre-stored data to authenticate the identity or data, and cannot verify the identity of the owner on the spot. By maliciously obtaining another person's wireless inductive device, it is possible to verify by misusing the identity of another person. Therefore, the current wireless inductive device needs further improvement in order to improve the safety in use.

Therefore, the present invention provides a wireless inductive device having a fingerprint identification function, which improves the safety of use of the wireless inductive device by identifying the owner's identity by the fingerprint identification function.

In order to achieve the above-mentioned object, the wireless inductive device equipped with the fingerprint identification function of the present invention can be used.

Taking the electronic key for access control as an example, the wireless inductive device of the present invention generates an inductive power supply as an operating power source for the chip and the fingerprint identification module when the wireless inductive device of the present invention approaches an inductive reader. can do. According to the present invention, by installing the fingerprint identification module, the user's finger can touch the surface of the case, and the fingerprint identification module can collect the fingerprint data of the user on the spot. Authentication data can be output to the inductive reader via the coil, thereby enabling identification. Since the fingerprint is a unique characteristic of the organism, even if the entry / exit control electronic key is obtained by a malicious person, the fingerprint data of the malicious person is the original of the entry / exit control electronic key. It is not identical to the owner's fingerprint data and the malicious person cannot pass the authentication of the inductive reader. Therefore, as compared with the existing wireless inductive device, the present invention improves the safety of use of the wireless inductive device by providing the fingerprint data in real time as the authentication basis.
