Abstract
Devices, systems, and techniques are provided for enabling device-to-device communications between a first device equipped with a fingerprint detection module that includes a metal contact and a second device equipped with a capacitive coupling port. In one aspect, a technique for enabling the device-to-device communications includes: positioning the first device and the second device so that the metal contact of the fingerprint detection module of the first device is in capacitive coupling with the capacitive coupling port of the second device; and establishing device-to-device communication between the first device and the second device through electrical signaling between the metal contact of the first device and the capacitive coupling port of the second device. During the device-to-device communication, the metal contact operates as a transmitting and receiving electrode for sending and receiving electrical signals to and from the capacitive coupling port.
