Use this trick fingerprint scanner to activate a real motion alarm system. Although fingerprint scanner seems realistic, The fingerprint scanner is intended for entertainment purposes only and does not provide true fingerprint scanning functionality. To have the scanner accept a fingerprint slide your finger across the screen and let go while on the scanner. You may slide your finger in any direction as long as you let go while inside the scanner. After a fingerprint is accepted the doors will slam shut and be in lockdown mode. Place the device down and any motion such as someone picking the device up will sound the alarm. Only an accepted fingerprint scan will turn the alarm off.
