<p>A system (100) and methods controls access to an accessed system (116) utilizing a two-factor requirement for admittance. One factor may be biometric data read (106) and extracted (110) from an individual wishing to gain access to the accessed system (116). The other factor maybe an electronic key (118) signal received at an input device (104) of the access control system that is converted to an input signal. In some instances, the input signal is used to access correlating biometric data in a memory (108). Then, the extracted live biometric data and the stored biometric data are compared to generate a matching result signal. The matching results signal is transmitted to a Wiegand access control panel (114) to control access to the accessed system (116). In other instances, the extracted live biometric data is compared to biometric data stored in a memory (108) corresponding to a plurality of individual's biometric data that are allowed access to the accessed system (116). If there is a match, an ID biometric signal is generated and transmitted to the Wiegand access control panel (114). Along with the ID biometric signal, and ID input signal is transmitted from an input device (104) to the Wiegand access control panel (114), where the ID input signal is based on receiving an electronic key (118) at the input device (104). Then, based on a comparison between the ID biometric signal and the ID input signal, the Wiegand access control panel (114) controls access to the accessed system (116).</p> |
