Abstract

Described herein are techniques related to a tap-to-wake and tap-to-login system. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope and meaning of the claims. A tap-to-wake and tap-to-login system allows a user of a near field device to wake up a computing platform from a deep sleep state using a bump/tap without having to move a mouse or enter a keyboard stroke.
