Fingerprint sensors

Here are the fingerprint sensors that have at least existed once, excepted (simple) optical sensors.

I know, this is a very very long page, because there are many tentatives and products, and I decidedto get all of them in one page -because having a hundred pages to manually manage would be tedious!

So I propose as a start just a list where you can click to go to the manufacturer you want to see.Another solution is to use the "find in the page" of your brother, or use google.

Silicon manufacturers are fabricating these sensors.

• (2007 Sep) Backed by a new $5 million investment from L-1 Identity Solutions, Ultra-Scan is working to develop and make a new fingerprint reader that is much smaller than current scanners and is able to scan four fingers, instead of just one.

• (2013 Mar) Qualcomm acquires Ultrascan.
• Ultrascan has developped an ultrasound TFT device, 4 fingers as announced in 2007.

• (2015 Mar) Qualcomm announces the launch of Qualcomm® Snapdragon Sense™ ID 3D Fingerprint Technology.
• It seems there are two demos at the MWC2015: a regular sensor, and the same(?) below a glass, to demonstrate the ability of capturing fingerprint through the display glass. In the last case, the image is becoming very noisy (this is maybe the reason why there is the logos on screen?). 3D image, they said... check out Vkansee to compare. It seems that dry fingers are still a problem...

  The biggest fingerprint AAD that GIS is capable of mass-producing measures 64 square millimeters (8x8mm). The company revealed a 600 square millimeter at Touch Taiwan 2019 last month, but GIS says the product is a work in progress.

• (2019 Dec) The 20x30mm sensor is unveiled. Announces 1 to 1 million FAR (like Apple for its FaceID), which could make sense when you acquire two fingers: the larger the sensing area, the better. Called "3D Sonic Max".
• About the Galaxy S10 disaster when using a cover:
  "It's practically impossible to try to predict what types of patterns will be available or what types of covers," Katouzian said. "We are constantly buying different covers and different materials to make sure the algorithm can tell the difference between a legitimate fingerprint and a spoof."

• (2021 Jan) Introducing Qualcomm 3D Sonic Sensor Gen 2
  Qualcomm 3D Sonic Sensor Gen 1 was 4x9mm (surface area 36mm²). Gen 2 will debut with a sensor that is 8x8 (64mm²).
• (2021 Jan) The sensor is released inside the Galaxy S21. Thank you JerryRigEverything for the teardown.
  This is not the very large 20x30mm sensor: likely too expensive.

• (2014 May) Goodix formerly known as Shenzhen Huiding Technology Co. Ltd. (a subsidiary of Mediatek, see also Elecvision), introduces a new active capacitance fingerprint sensor. Goodix presentation (OFweek).
  By adopting a new original patented packaging technology, Goodix integrated the metal ring, sapphire cover and sensor into a small volume. The mode of operation is similar with Apple Touch ID technology. Products: GF6616, GF6626, GF6610 and GF6620. Minimum size is only 9.76mm x7.4mm x1.17mm.
  Announced accuracy: FAR 1/50000 for a FRR 1/100 (at least, they give the FRR: Apple said nothing about that).

• (2014 Sep) Goodix unveils their new generation of fingerprint identification solution - IFS (Invisible Fingerprint Sensor), developped with TPK which should enable to remove the ring, and use directly glass (450 to 700 microns thick).
  300 microns sapphire protection (like the Apple 5S).

• (2015 Jan) Goodix announces that their GF66X8 fingerprint sensor powers Meizu’s latest smartphone (the Meizu MX4).
  Several parts exist, depending on the color/package:
  {circle, square, rectangle}, {white, black}
  Likely the same sensor behind. 96×96 pixels, maybe in 3 x (32x96), TBC.
  You can find some more information at Chipworks (under the name GT6648, reverse of the Meizu phone).
