- Hundreds of different fingerprint sensor products have been proposed by many companies and universities, it's a jungle, but now, less and less new products are released.
- Capturing a live fingerprint is not enough : you need a fingerprint algorithm to match two fingerprints.
- Some tried to integrate the sensor and the algorithm, a system-on-chip.
And so many applications using fingerprints exist, I'm sure that you don't know some of them, you will discover that in my website. Maybe the most important :
- Smartphones are the most common application using fingerprint sensors. The very first in 1998.
- Notebooks is also using fingerprint sensors, but not as much as smartphones. I made and presented the very first notebook prototype with a fingerprint sensor in 1998.
- Smartcard with an integrated fingerprint sensor is a big challenge, many tried to do so, including myself.
I made a history of products having used a fingerprint sensor.
