BMF introduced in 2003 a biometric sensor based on TFT-material. It was a so-called pressure sensitive sensor. Through various layers of material an image of the fingerprint was created solely by a simple pressure of the finger on the reader. Big benefit: you could read the fingerprint under almost every circumstances even "under" water (see picture). It was sold in Europe via Hitachi. I was really impressed.
