<p>The invention relates to a Bluetooth-controlled access and presence control system comprising the biometric reading of parts of the hand, including a sensor that facilitates the identification or non-identification of a user by means of optical recognition of pre-determined parts of one of the user's hands, extraction of characteristics and electronic comparison with a database, so as to produce an identification or non-identification output that can be used to control a door, access or the like. The system also includes a digital signal processor, a control panel with at least one microcontroller, at least one relay for controlling access and a Bluetooth module that communicates with the digital signal processor.</p> |
