Porque é que não podemos registar o Palm Pay utilizando a câmara do telemóvel? - Informações sobre a tecnologia do WeChat Pay e do BioWavePass Palm Pay

🌐 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 veias da palma da mão.

Process Overview:

1. User agrees in the WeChat App to activate Palm Pay.
2. User visits a certified terminal with a palm scanner.
3. The scanner captures RGB + IR images of the palm’s structure and vein network.
4. 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.
• O 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.

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