Uses should place the module a little far away from the buzzer; if the distance is too close, the sound of the buzzer will be low Applications: Attendance Fingerprint Read Write Module Entrance Guard Intercom Read Write Module Replicator Attendance fingerprint card reader module Entrance guard intercom card reader module Size:4.7x2.6cm/1.85x1.02inch Note: Please allow 1-3mm error due to manual measurement.pls make sure you do not mind before you bid.
