The EPT-212 at Chalmun's Cantina The EPT-212, a security gadget, was created by Fabritech. It was designed to detect the unique wireless signals and power cell vibrations emitted by droids.
To keep droids out of his Mos Eisley Cantina, Chalmun had a reconditioned EPT-212 installed. Dathcha pilfered it at one stage, but a nearby spacer gave it back.
