Human interface and biometrics firm Synaptics has revealed the Natural ID FS4304, an ultra-slim area-touch biometric fingerprint sensor designed to fit small spaces such as the edge of smartphones or tablets.In a statement, Synaptics noted that FS4304 is only 3.5mm wide and that it can be integrated into side-mounted buttons, such as the volume rocker. The company notes that this ultimately eliminates the footprint and cost required of creating an additional cutout in the frame.”Synaptics' FS4300 family is market-proven with over 50 million units shipped into mass production, and with this new ultra-slim format OEMs can differentiate by designing fingerprint into a variety of small spaces,” said Ritu Favre, senior vice president and general manager, Biometrics Product Division, Synaptics.”The rapid growth of secure fingerprint authentication across multiple markets, including China and mid- to lower-end smartphone models, is driving our leading portfolio of solutions.” Synaptics also today revealed that it has added an advanced anti-spoofing solution to its SentryPoint security suite.SentryPoint enables secure personal authentication for transactions – commonly executed through intelligent devices such as smartphones and personal computers – that are critical to banks, mobile/online payment services, and the prevention of consumer identity theft.”Synaptics is acutely addressing the rapid growth in fingerprint sensor adoption and the rise in mobile payment platforms, by delivering SentryPoint to allay security concerns of identity theft. The SentryPoint security suite is unmatched and provides assurances to both service providers and end users that only those authorized are executing transactions,” said Anthony Gioeli, vice president of marketing, Biometrics Product Division, Synaptics. “Even if the host system is compromised by malware or other attacks, SentryPoint provides an added layer of protection for the user's biometric data.”
