Code cylinder

"The self-styled commander looks every bit an officer, and he used code cylinders to requisition the fuel cells."

- Moff Tarkin

A code cylinder was a security device in the shape of a short cylinder that was used by the Galactic Empire. It contained coded information about its wearer. Code cylinders were typically carried in narrow pockets just below each shoulder of the Imperial military uniform. There existed at least two physically distinct kinds of code cylinder: one had a blue bulbous surface at its tip and a small pocket clip (there was a variant carried by Chief Bast and General Tagge without the blue cap), while the other was thicker and structured with a spiral drill bulb at the top. The number of code cylinders carried depended on the officer; aboard the first Death Star, Grand Moff Tarkin possessed four cylinders, while General Cassio Tagge and Admiral Conan Antonio Motti carried only three of them.
