A security deterrent that disables a laptop if it doesn't check in with a monitoring centre has value only if thieves know the deterrent is active. A sticker that includes the "deactivation date" of the laptop is a more convincing reminder than a sticker alone. Disclosed is a design for a distinctive marker (such as a sticker) on the laptop, incorporating the disable date such that it can be updated electronically when the laptop checks in with the monitoring centre. By making this clearly visible, it should be obvious to any potential thief that the laptop will not work for long after being stolen, increasing the deterrent effect of the security system.

Home security, car alarms, businesses, and anything else with security protection places value in clearly informing potential thieves that security is being enforced by a supplemental system that a thief might not already have noticed.

In this proposal, there is provided a concrete notice that should be conveyed, e.g. "This computer will be deactivated on 13 January 2009 unless an authorized person logs in." This will be more useful than a simple sticker, in the same way that a voicemail message that speaks the current date is perceived as more reliable. It could be done

without any significant power cost by using

                            "Electronic Paper" that updates the expiry date whenever the security module checks in.

An LCD display would also work, but

would be harder to build into the laptop case.

The date could be updated using a low-power technology, like the upcoming "Ultra-Low Energy Bluetooth" or other radio standard designed for communication with wrist


      (long battery life). This would involve a button-style battery and small amount of circuitry in the sticker.

Alternatively, the e-paper could be connected by thin USB

connector to an external port (possibly built into the case for that purpose). In this latter case, USB would provide both the signal and the necessary power to change the displayed date.

An added advantage of this system is that it would remind legitimate users that the

feature is in place, an...
