Off chip sensing has the advantage of separation of the ASIC and the sensing array which enables form factory flexibility, low cost and high biometric performance.
From a range of technologies applicable for fingerprint sensors, capacitive fingerprint technology has been validated by titans such as Apple, Samsung and Huawei as the dominant technology for mobile devices due to compact size and low cost. Almost a billion capacitive fingerprint sensors are expected to be deployed by Apple, Samsung and other OEMs in 2017.
To succeed in the fingerprint sensor business it’s imperative to have a strong understanding of technology and possess a solid patent portfolio. IDEX have developed its know-how for over twenty years, and owns the strongest core IP in AC/RF capacitive fingerprint sensing outside Apple.
Conventional silicon sensing has significant end user adoption, compelling cost points for smaller sized sensor geometries and a good fit in rigid applications such as existing mobile handsets.
Algorithms are an integral part of a high performance fingerprint matching system. The purpose of the algorithm is to derive high quality match scores through the comparison of a stored fingerprint template to a live touch image. As touch sensors have evolved to increasingly smaller geometries based the limited real estate on today’s smart phones, […]
