Ingenico’s biometric terminals keep fraud at bay through a layered security approach. The biometric scan is captured locally and turned into a one‑way, encrypted template that never leaves the device, so attackers can’t steal raw fingerprint, palm‑vein, facial or iris data. Built‑in liveness‑detection sensors verify that the presented trait is from a live person, thwarting fake fingers, printed images or video replay attacks. All cryptographic keys reside in a tamper‑resistant hardware security module, and the terminal’s firmware enforces secure key‑injection and end‑to‑end encryption. Additionally, Ingenico devices embed anti‑skimming sensors and integrate with the Ingenico 360 alert service, which continuously monitors for abnormal behavior and can instantly block compromised terminals, further protecting against fraud and spoofing.
