# Heartbeat-Based Biometric Logins Monacoeur Reads Cardiac Rhythms at 1,000 Hz to Verify Users By Adam Harrie | Written with AI assistance | Published 2026-10-08 | Business Source: Trend Hunter, https://www.trendhunter.com/trends/heartbeat-based-biometric-logins References: [biometricupdate](https://www.biometricupdate.com/202610/monaco-startup-advances-heartbeat-biometric-authentication)  Monacoeur is testing a login method that lets people prove who they are with a heartbeat instead of a password or face scan. The Monaco startup built the biometric system to read cardiac rhythms through high-frequency sensors, with AI checking whether the pattern matches the user. Its sensors capture cardiac activity at 1,000 Hz, giving the software a detailed pattern to compare during sign-in or a transaction. Monacoeur has already turned the tech into prototype bracelets used by several French banks, showing how the concept can move from controlled testing into everyday payment approval. For brands, this opens room for access and payment systems that add a harder-to-copy body cue without asking users to learn a new routine. In security-heavy settings such as banking, password and face-based check-ins now have a wearable alternative. That keeps the format close to devices people already wear.
