Abstract

Apparatus, methods, and systems described herein are for segmentation, handshaking, and access control solutions for Opendots technology. One embodiment described a charging pad that includes a plurality of conductive strips, switches, and decipher circuitry. A switch is coupled to the plurality of conductive strips whereas the decipher circuitry is coupled to the plurality of conductive strips and the switch. In response to contact with one conductive strip of the plurality of conductive strips, the decipher circuitry determines whether a security password has been received. The switch allows a voltage higher than a threshold voltage level to be supplied to an external device if the security password is received by the decipher circuitry. However, the switch can also prevent a voltage higher than a threshold voltage level to be supplied to an external device if the security password is not received by the decipher circuitry.
