Multimodal biometrics have attracted attention in terms of improving its accuracy. However, imagers that can simultaneously capture fingerprint and finger vein images have not been realized. Here, we report flexible organic photodetectors with two active layers that can selectively detect visible and near-infrared light, which are used for fingerprint and finger vein multimodal authentication.
