An on-premise processing architecture where palm vein authentication and transaction authorization occur directly on the local terminal. This model ensures maximum speed and can operate without an internet connection.
• All biometric data is processed and stored locally on the device
• Enables instant verification without cloud server latency
• Guarantees functionality in offline or low-connectivity environments
• Ideal for fixed point-of-sale locations requiring high throughput

A centralized architecture where the terminal captures the biometric data and sends it to a secure cloud server for verification. The cloud handles authentication, linking to payment methods, and transaction processing.
• User's biometric template is stored securely in the cloud
• Allows users to pay at any terminal within the entire network
• Enables centralized account management, analytics, and updates
• Requires a stable internet connection at the point of sale

A hybrid architecture that merges the speed of terminal payments with the scalability of cloud services. The system can process transactions locally for speed and resilience, while syncing with the cloud for centralized data management.
• Combines local processing for speed with cloud-based user profiles
• Supports offline transactions that are synchronized when connectivity returns
• Offers the highest level of reliability and flexibility for diverse environments
• Ideal for large-scale deployments with varying internet quality
