Biometric Subsystem: Dedicated signal processing unit for continuous heart pattern analysis with 99.98% accuracy and anti-spoofing capabilities
SoC Architecture: Custom designed ARM Cortex-M4F microprocessor operating at ultra-low power consumption (0.8mW at idle)
Memory Configuration: 512KB secure encrypted flash memory and 128KB SRAM with hardware memory protection
Communication Modules: NFC (13.56MHz ISO/IEC 14443), Bluetooth 5.2 with BLE, ultra-wideband (UWB) for precise spatial awareness
Security Subsystem
PayPIN Ring's security stack implements defense-in-depth strategy across multiple layers:
Hardware Security: Physical unclonable function (PUF) for unique device fingerprinting, side-channel attack resistance, and tamper detection circuits
Cryptographic Implementation:
- AES-256 for symmetric encryption
- ECC (secp256k1/P-256) for asymmetric cryptography
- HMAC-SHA256 for authentication codes
- zkSNARK compatibility for zero-knowledge proofs
Key Management: Hardware-based true random number generator (TRNG), hierarchical deterministic key derivation (BIP32/39/44), and secure key isolation
Firmware Security: Secure boot with signature verification, runtime integrity monitoring, and over-the-air updates with rollback protection
Biometric Processing Pipeline
The heart biometric system employs a sophisticated multi-stage processing pipeline:
Signal Acquisition: Dual-wavelength photoplethysmography (PPG) sensors sample at 200Hz
Noise Reduction: Adaptive filtering with motion artifact compensation
Feature Extraction: Wavelet transform analysis extracting 64 unique cardiac identifiers
Template Generation: Conversion to encrypted biometric templates (non-reversible)
