Fingerprint

Fingerprint (formerly FingerprintJS) is a device-identification and fraud-prevention platform. Its browser and mobile agents generate a stable visitorId, and the Server API returns detailed identification events enriched with Smart Signals (bot, VPN, proxy, tampering, emulator, and more) for account takeover, payment fraud, and bot-mitigation use cases.
