Description

technical field

[0001] The invention relates to the field of access control machines, in particular to an access control machine capable of fingerprint identification under the screen. Background technique

[0002] Biometric technology is listed as one of the technologies that have a huge impact on human production and life in the new century. Biometric identification is currently the most convenient and safe identification technology. Biometric identification technology identifies the person himself and does not require markers other than the person. Biometric recognition technology uses human physiological and behavioral characteristics for identification, mainly including the following categories, fingerprint recognition, face recognition, iris recognition, gait recognition, etc. Among them, fingerprint recognition is a widely used recognition technology.

[0003] The fingerprint identification module of existing access control machine is generally positioned at the bel...
