The Cryptographic Sequencer is a gadget employed by Batman. It is a device used to hack into security consoles and unlock access to secure areas. After recovering an encryption key, the Sequencer enables its user to lock onto secure radio broadcasts which are subsequently stored, tracked, and played back by the Batcomputer.
