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.

    摘要: The disclosed technology provides optical anti-proofing techniques in fingerprints sensing in devices or systems that use fingerprint identification for controlling access. The disclosed technology uses a fingerprint sensor to detect a contact input associated with a source of a fingerprint; generates an image signal from the fingerprint sensor responsive to the detected contact input that is indicative of one or more images of the fingerprint; uses an optical biometric sensor that is separate from the fingerprint sensor to generate a biometric marker detection signal indicative of a biometric marker different from the fingerprint; and processes, by processing circuitry, the generated image signal and the biometric marker detection signal to determine whether the detected contact and the associated one or more fingerprint images are from a finger of a live person who makes the contact input.
