Abstract
A device includes a first biometric sensor formed on a substrate and configured to access a first biometric feature of a user, and a second biometric sensor arranged under the first biometric sensor and configured to access second a biometric feature of the user. The second biometric sensor includes a light emitter configured to emit light to reach the user through the substrate and receive a reflection light for deriving the second biometric feature.
