One variation of a system includes: a substrate including an aperture and a multi-layer inductor; and a cover layer arranged over the substrate and cooperating with the aperture to define a housing. Additionally, the system includes a fingerprint reader arranged within the housing and configured to permeate through the cover layer to scan a fingerprint applied over the cover layer. A magnetic element is arranged facing the multi-layer inductor and configured to inductively couple the multi-layer inductor. The system further includes a controller configured to: read electrical values from the multi-layer inductor; and register a fingerprint input on the cover layer based on the electrical values. Additionally, the controller can: read fingerprint values from the fingerprint reader to generate a fingerprint image; and trigger a first oscillating voltage across the multi-layer inductor to oscillate the cover layer in response to the fingerprint image deviating from a target fingerprint image.
