Devices and complexes of destruction of the information on magnetic carriers: Are the police busting down your door right now? Are you afraid they’ll find all the pirated movies on your computer? Quick, hit the “Emergency EMP” button…
Devices for the emergency data destruction from magnetic media are designed for instant and non-recoverable destruction of confidential information in case of danger of its outflow or disclosure, plunder or withdrawal of the computer system block (the media with the data).
The site is in very stilted English, but the gist is that they’ll sell you devices that will generate a localized electromagnetic pulse to destroy data (and a lot of other stuff) in a big hurry. You can even activate it from a keychain trigger — handy.
