One of the most common questions we receive from fintech companies and software development teams is:
"If we start with the free Small Model (10,000 IDs), what happens when our user base grows? Will all users need to register again when upgrading to the Large Scale Model?"
The answer is No.
At X-Telcom, the Small Model is designed for MVP testing, pilot projects, and early-stage deployments. It supports up to 10,000 free user IDs, allowing fintech companies to validate their business model before investing in larger-scale infrastructure.
The key is planning for future growth from day one.
When users are enrolled, we strongly recommend storing both:
- Palm Print Images (RGB)
- Palm Vein Images (IR)
These images become the foundation for future migration.
When it’s time to upgrade to the Large Scale Model, the application simply calls the Large Model registration interface and uses the previously stored RGB and IR registration images.
From the algorithm’s perspective, this is a new registration into the Large Scale Model database because the large model performs additional server-side processing using the original images.
However, from the user’s perspective, nothing changes.
Users do not need to:
- Register again
- Scan their palm again
- Visit an enrollment location
- Repeat onboarding procedures
The migration can be completed programmatically using the images already stored by the platform.
This is one of the biggest advantages of a properly designed palm payment architecture. Scaling becomes a software process, not a user process.
Small Model
- Up to 10,000 free IDs
- Uses end-side Palm Print Features (RGB)
- Uses end-side Palm Vein Features (IR)
- Ideal for MVP and pilot deployments
Large Scale Model
- Supports 100K to millions of users
- Uses stored RGB and IR images
- Performs server-side feature re-extraction
- Designed for large-scale commercial deployments
For development teams, migration is straightforward:
- Existing registration images are reused
- Large Model registration is completed automatically
- No SDK redesign is required
- Only device-server communication interfaces and server APIs need adjustment
