Why Should Palm Images Be Saved in Advance?

When building Palm Vein Technology or Palm Pay systems, one key question often arises:
“Why should palm images be saved in advance?”

At BioWavePass (by X-Telcom), saving palm images is not about storing unnecessary data — it’s a crucial step that ensures security, flexibility, and long-term scalability for biometric solutions.

🔍 Why Saving Palm Images Matters

1️⃣ To keep a reliable reference
Each palm image serves as a permanent base record in the client’s local database.
If only extracted feature vectors are stored, part of the original biometric information could be lost — making future verification or algorithm upgrades impossible.

2️⃣ Small model: fast, local, and image-free
Our small-model algorithm (already built into the SDK) performs all matching on the server ( up to 10,000 user IDs free).
It compares extracted palm print and palm vein features (RGB + IR) without accessing the original image.
The saved image simply acts as a secure backup.

3️⃣ Large model: When user qty over 10,000
When upgraded to the large-model algorithm, the system re-extracts palm print and vein features from end-side & server-side palm images.

This enables higher accuracy and scalability for Palm Pay, eKYC, and national ID projects.

🧠 Inside the BioWavePass Algorithm Design

• Small Model: End-device palm print + palm vein features (fast, offline).
• Large Model: End-device features + server-based re-extraction for deep learning verification (cloud-assisted).

This architecture allows BioWavePass to deliver both speed on the edge and accuracy at scale, ensuring future-proof Palm Vein Technology.

🌍 Why Developers Choose BioWavePass

BioWavePass (X-Telcom) offers a complete ecosystem — from algorithm to hardware — for secure biometric integration:

• ⚙️ Palm Vein Scanner SDK — optimized for Android and embedded platforms with Flutter support.
• 🔒 High accuracy & speed — 99% match rate, 0.35s comparison time, powered by RGB + IR dual-spectrum algorithm.
• 🏗️ Stable commercial hardware — proven, production-ready Palm Vein Scanners for real-world deployments.
• 🧩 Custom hardware service — flexible designs for unique project needs and integrations.
• 🌍 End-to-end solution team — located in the UK and India, supporting both sandbox demos and full commercial systems.

✅ By saving palm images early, you avoid forcing users to re-register when switching from the small to large model — ensuring a seamless upgrade path.
