Abstract: The present disclosure relates to computer-implemented systems and methods for establishing communication using a body area network. A system may receive, by a capacitive sensor, a touch interaction from a user. Furthermore, the system may determine, by the capacitive sensor based at least in part on the touch interaction, a change in capacitance. In addition, the system may transmit, via the user's body in response to the change in capacitance, a request to a user device for credential information. The system may also receive, from the user device via the user's body, the credential information.
