Problems solved by technology

[0006] However, the aforementioned fingerprint identification device must require continuous power supply, so the conventional fingerprint identification device needs to frequently replace the battery or charge the power supply.
In addition, since the fingerprint identification device must obtain more than a certain proportion of fingerprint lines when identifying the fingerprint of the finger, however, the conventional fingerprint identification device does not have a mechanism for confirming that the finger has been positioned, resulting in the finger not being in close contact with the fingerprint identification device. The chip-type fingerprint sensor board has already started the identification process, so the stability of its identification results has not been ideal

Embodiment Construction

[0025] see figure 1 , figure 1 It is a schematic diagram of the fingerprint switch and the control board for the press-activated identification of the present invention. Such as figure 1 As shown, the activator 12 in the fingerprint switch 1 for press-activated identification of the present invention is arranged on the surface of the fingerprint sensor board 13 . When the activator 12 receives an acceptable finger movement, it sends an activation command, and transmits the activation command to the control board 2 via the serial transmission interface 16, and the control board 2 will thus enable the power supply of the battery 26 to start the fingerprint identification switch 1. powered by. Because the activator 12 is arranged on a small area on the fingerprint sensor board 13, and the fingerprint sensor board 13 and the push switch 14 have a relationship of up and down positions (there will be clearer icons to indicate their relative positions later), so Therefore, the fi...

Abstract

The invention provides a fingerprint recognition switch activated by pressing. The fingerprint recognition module comprises activator, to produce acute position signal and obtain power after receiving activate command that is finger takes action activator can receive; press switch, to run recognition program that is run by the program and produce recognition result if being pressed after obtain power; fingerprint sensing plate, that is on top of press switch and used to obtain fingerprint; and fingerprint recognition processor. When finger forces on fingerprint sensing plate, it presses indirectly the press witch; and as finger is very close to fingerprint sensing plate, ob needed fingerprint for recognition program, then run recognition program.

Description

technical field [0001] The invention relates to a fingerprint identification switch activated by pressing, in particular to a fingerprint identification switch which can save power and has high stability. Background technique [0002] By identifying the unique biological characteristics of individuals, such as fingerprints, voiceprints, handwriting, irises, etc., methods have been gradually developed to provide a relatively complete and effective way of identity verification. Its advantage is that the biometric feature is portable and does not need to be memorized, and it cannot be stolen. In particular, the biometric identity verification method combined with fingerprints is not only strict, but also quite convenient to use. [0003] The traditional fingerprint identification system uses the fingerprint collector to capture the fingerprint image data, and then transmits the fingerprint image data to the back-end terminal host through the interface signal to process the fing...
