Patent number: 12205429Abstract: An access control system and a method for operating an access control system are provided. The access control system includes a camera and an access control device and may additionally include a local processing device. At least one of the camera, the access control device, and the local processing device (when included) may be used to store a biometric identifier (e.g., in a storage medium) and compare an optical image with the biometric identifier (e.g., in an authentication module) to decide whether or not a mechanical or electronic lock should be unlocked. The camera, the access control device, and the local processing device (when included) are in short-range communication (e.g., to transmit the optical image and/or an authentication signal). The use of short-range communication allows the comparison of the optical image with the stored biometric identifier to be done locally instead of remotely (e.g., in a sever).Type: GrantFiled: May 20, 2021Date of Patent: January 21, 2025Assignee: CARRIER CORPORATIONInventors: Adam Kuenzi, Yuri Novozhenets, Andre Lalande, Mark H.
