Tencent Cloud PalmAI

Tencent Cloud PalmAI is a palm recognition and identity verification service. It uses palm and palm vein scanning technology to verify people's identities for payments, access control, and KYC (Know Your Customer) processes. Instead of remembering passwords or carrying cards, users just hold their hand near a scanner. The system matches palm vein patterns, which are unique to each person, against a registered database. It handles everything from subway fare gates to office building entry.

The technology boasts 99.99% recognition accuracy and responses in under 300 milliseconds. Data is encrypted with AES 256, and the system uses a dedicated encryption chip. Tencent has tested the algorithm on over 50 million users. The service comes in three tiers: Standard for basic access control, KycMax for identity verification at scale, and PayMax for high-security payment scenarios. An open API and partner hardware ecosystem let businesses pick compatible scanners and integrate the software into their own systems.

This tool is best for large organizations that need fast, contactless identity checks. Transit authorities, retail chains, banks, and property managers are the primary buyers. Real-world deployments include Beijing's Daxing Airport subway line (palm fare payment), 7-Eleven stores (checkout without cash or phone), and CapitaLand buildings in Singapore (tenant access control). The system also works with consumer products — Xiaomi smart door locks use palm vein scanning to let residents unlock doors with a wave.
