Abstract

Apparatus, methods, and systems are herein described for segmentation, handshaking, and access control solutions for Opendots technology. The present disclosure provides a charging pad that includes a plurality of conductive strips, switches, and decipher circuitry. A switch may be coupled to the conductive strips whereas the decipher circuitry may be coupled to the conductive strips and the switch. In response to contact with one of the 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 may 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.
