Techniques for fully-differential multi-phase scanning in capacitive fingerprint applications are described herein. In an example embodiment, a system comprises a capacitive fingerprint sensor array and a processing device coupled to the capacitive fingerprint sensor array. The processing device is configured at least to: scan the capacitive fingerprint sensor array in a fully-differential multi-phase mode; receive a plurality of measurements that represents a portion of finger on the capacitive fingerprint sensor array; and generate a fingerprint image for the portion of the finger based on the plurality of measurements.
