 ### :material-lightning-bolt: Capacitive Fingerprint Sensors
 
-Capacitive sensors measure the electrical conductivity of your finger. These are much more secure than optical sensors since they can't be fooled with an image. They're also tough to fool with prosthetics as different materials will have different electical properties.
