Verifying identity and making secure electronic transactions were once primarily the domain of simple passwords and PINs -- all inevitably at risk of being compromised. A compelling alternative to those imperfect methods is fingerprint authentication, which enables a user's biometric identity to replace a password or PIN. Synaptics is leading the charge in this field with its Natural ID™ capacitive-based fingerprint solutions -- combining secure biometrics and advanced encryption into a family of fingerprint-authentication sensors enabling applications such as PC and Auto with the highest levels of security, ease of use, and cost efficiency.
