Description

Wireless sensor device with fingerprint identification function

A wireless sensor device, especially a wireless sensor device with fingerprint recognition function.

Wireless induction devices usually use radio frequency identification (Radio Frequency Identification, RFID) technology. They include an induction coil and a chip. The chip is electrically connected to the induction coil. When the wireless induction device approaches an inductive reader, it senses the induction. When the AC magnetic field is emitted by the reader, due to electromagnetic induction, the induction coil generates current to supply power to the chip, and then the chip transmits the data stored in the chip to the inductive reader for the inductive reader. The reader identifies the wireless sensor device according to the data.

Existing wireless sensor devices are often used for access control or personnel identification in companies, schools and other places. For example, the wireless sensor device held by each employee can store different employee data, and the company’s inductive reader receives wireless The employee data transmitted by the sensor device, and the employee's identity is identified based on the employee data.

However, the existing wireless sensor devices only provide pre-stored data to the sensor reader for identity or data authentication, and cannot confirm the identity of the current holder. Those who are interested can use other people’s wireless sensor devices to pretend to be Using the identity of others to verify, it can be seen that the current wireless sensing device needs further improvement to improve the safety of the wireless sensing device in use.

In view of this, the present invention provides a wireless sensor device with fingerprint recognition function, which recognizes the identity of the holder through the fingerprint recognition function, so as to improve the security of using the wireless sensor device.

To achieve the foregoing objective, the wireless sensor device with fingerprint recognition function of the present invention includes: a housing; a coil arranged in the housing; a chip arranged in the housing and electrically connected to the coil; and a fingerprint recognition The module is arranged in the casing and electrically connected to the coil and the chip, and includes a fingerprint sensor.

The wireless sensor device of the present invention takes an access control magnetic buckle as an example. When the present invention is close to an inductive reader, the coil can generate an inductive power supply to the chip and the fingerprint recognition module as a working power source. The present invention uses the fingerprint recognition The module is arranged so that the user’s finger can touch the surface of the housing, so that the fingerprint recognition module can capture a fingerprint data of the current user, and the chip can output an authentication data to the inductive type through the coil Reader for identification. Because fingerprints are unique biological characteristics, even if the magnetic door lock is obtained by a caring person, the fingerprint data of the caring person is not the same as the fingerprint data of the original holder of the magnetic door lock, and the caring person cannot pass the Authentication of inductive readers. Therefore, compared with the conventional wireless sensor device, the present invention provides the real-time fingerprint data as an authentication basis, thereby improving the security of using the wireless sensor device.
