Abstract

A portable electronic device having a suspend mode and a work mode is illustrated. The portable electronic device includes a body, a touch sense module and an identifying module. The body includes a casing. The touch sense module has a plurality of touch sensors disposed on the surface of the casing and used for sensing a contact gesture of a user. The identifying module is placed in the body and used for retrieving an identification data. When the portable electronic device is switched to the suspend mode, the touch sense module is enabled to sense the contact gesture. When the contact gesture matches a predetermined gesture, the identifying module is enabled to retrieve the identification data wirelessly. The portable electronic device is switched from the suspend mode to the work mode when is the identification data is confirmed.
