KEY FEATURES

  • Face Detection and Recognition – An inbuilt tilt camera adjusts its angle based on the user’s height.
  • Face authentication in the dark is possible because of the dual camera’s IR (containing an IR LED) and color cameras.
  • PIV Certified FBI Sensor
  • Dual CPU – Face and fingerprint authentication at the same time
  • Dual Card Support – RF and Smart Card Recognition at the Same Time
  • 5″ Color Touch LCD – User-friendly User Interface – Increased Touch Sensitivity
  • Superior Matching Engine – FVC’s top-ranked algorithm (Fingerprint Verification Competition) The use of fake fingerprint detection technology ensures the highest level of security.
  • Multifactor Authentication–
  • Face, Fingerprint, Card, PIN Authentication
  • 1:1, 1: N Fingerprint authentication, shortcut ID, etc.
  • Crash Report System – When an error occurs, an analytical report is generated.
