🌐 Introduction

Palm-based biometric payment is changing how the world authenticates identity.
Platforms like Tencent WeChat Pay have already proven its reliability through Palm Pay, where users simply wave their hands to complete payments.

But a simple question keeps surfacing:

“Why can’t we just use a phone camera to register our palm?”

The answer lies in how real biometric data is captured, encrypted, and verified.
Let’s explore the exact registration flow used by WeChat Pay, and why X-Telcom’s BioWavePass adopts the same hardware-based RGB + IR technology for secure and accurate palm recognition.

🔒 WeChat (Tencent) Palm Pay Registration Process

1️⃣ Registration Entry

Users begin registration inside the WeChat App via WeChat Pay → Biometrics → Palm.
The phone only acts as an authorization gateway, not for biometric capture.
Tencent confirmed that mobile registration via phone cameras was tested but later disabled due to inaccuracy and security risks.
All active registrations now require a certified Palm Vein Scanner device.

2️⃣ Registration Method

Palm registration cannot be completed on a smartphone.
It requires a POS terminal, kiosk, or access gate equipped with a Scanner de veine de la main.

Process Overview:

User agrees in the WeChat App to activate Palm Pay.
User visits a certified terminal with a palm scanner.
The scanner captures Images RVB + IR of the palm’s structure and vein network.
The encrypted data is uploaded securely to WeChat Pay’s backend, where a unique token links the palm to the user’s account.

3️⃣ Data Binding

The merchant terminal does not store any biometric data.
Palm data is encrypted and securely stored in Tencent’s backend database.
Le Palm ID is bound to the user’s WeChat account and linked bank card/wallet.

4️⃣ Usage Scenarios

Once registration is complete, users can simply wave their palm to pay — no card or phone required.

✅ Typical scenarios include:

Public transportation (bus, metro, gate)
Retail checkout and vending kiosks
Smart access and identity verification systems

This seamless experience is only possible through certified RGB + IR hardware, ensuring both precision and safety.

📸 Why Smartphones Can’t Replace Palm Vein Devices

Smartphone cameras capture color (RGB) — but not infrared (IR) light, which is essential for detecting subcutaneous vein patterns unique to each person.

Limitation	Explanation
No Infrared Imaging	Palm Vein scanners use IR to detect blood vessel patterns under the skin — invisible to normal cameras.
Lighting Variations	Smartphone photos fluctuate with ambient light, angles, and distance — causing unstable biometric data.
No Real-Time Encryption	Certified scanners encrypt data instantly, while phones can’t meet financial-grade encryption standards.

That’s why WeChat Pay — and now BioWavePass — insist on RGB + IR scanners for secure biometric registration.

💡 BioWavePass: Global Palm Vein Payment Solution

Au BioWavePass, we designed Palm Vein Technology using the same technical logic proven by WeChat Pay — combining RGB + IR sensors, AI-based image fusion, and on-device encryption.

Core Highlights:

✅ Dual-spectrum imaging (RGB + IR) for unmatched accuracy and anti-spoofing.
⚡ Recognition speed: 0.35 seconds with 99% success rate in databases over 5 million IDs.
🧠 AI-driven algorithm ensures precision even under poor lighting.
🔒 Full SDK/API support for payment, eKYC, and access systems.

Key Devices:

WavePass500 Android Palm Vein Payment Terminal
PalmVein01 Lecteur de veine palmaire USB (Windows / Linux / Android)

These devices ensure compliant, encrypted, and scalable palm registration for global partners.

🌍 From WeChat Pay to Worldwide Adoption

Le WeChat Palm Pay model proves that accurate palm registration must depend on certified RGB + IR hardware.
BioWavePass extends this standard globally — enabling:

Secure palm registration for digital wallets and payment platforms.
Integration into fintech, government, and smart city systems.
Deployment across POS terminals, kiosks, and transport gates.

✅ Conclusion

A phone camera can see your hand — but only RGB + IR technology can identify who you are.

The lesson from Tencent WeChat Pay is clear:
Palm Pay registration must use certified RGB + IR scanners to ensure security, accuracy, and compliance.

Avec BioWavePass Palm Vein Technology, this proven model is now available worldwide — bringing reliable, touch-free, and intelligent payment solutions to every market.
