Summoning chip

"The hyperwave receiver is equipped with summoning chips and transponding antennae similar to ones we discovered in a mine-laying chameleon droid Master Yoda brought back from Ilum."

- Dyne

Summoning chips were a type of specialized chips that could send summon signals, telling their owners to contact those who sent those signals. Darth Sidious used such devices during the Invasion of Naboo when he needed to summon his Trade Federation allies.
