In article number 2000562, Zhengwen Yang, Bitao Liu, and co‐workers present a method of fingerprint acquisition, obtained by means of the photo‐thermal‐chromism of MoO 3 photochromism ceramic upon irradiation of multiband light outside the bandgap, which breaks the limitation of photochromism caused by monochromatic wavelength inside the band gap. The acquisition fingerprint based on the photochromism of MoO 3 ceramic exhibits excellent repeatability, high reproducibility and long preservation persistence under heat‐treatment.
