Community corrections supervision relies on manual check-ins, phone spot checks and paper ledgers, making field verification slow and records fragmented. Justice bureaus deployed SIZON M5 handheld ID terminals in batch for field staff, with two business apps: voiceprint collection and the Correction Mobile Office platform.

Devices were delivered ready-to-use: batch stocking, per-unit testing and system pre-configuration completed by SIZON so staff can log in to the platform out of the box.

The voiceprint collection app is an auxiliary tool for community corrections, mainly used to collect voiceprint data of supervised persons. Staff complete on-site collection with the M5: voiceprints are bound to verified identity data into a one-person-one-archive; the guided workflow is simple enough for non-specialist staff, greatly standardizing information collection and providing a reliable voiceprint baseline for phone spot checks and remote verification.

Built on the M5 Android 12 platform with 4G connectivity, voiceprint data is encrypted and synced to the corrections management platform in real time, replacing error-prone paper registration.

The Correction Mobile Office platform lets staff handle case management, location checking, visit records, education support and approvals on the go: on-site ID verification and real-time registration of check-ins, study and community service; BeiDou/GPS positioning with platform comparison for anomalies; geo-tagged visit records with digital notes; and mobile approval of leave requests and routine matters.

One M5 integrates online ID card verification, fingerprint/face multi-modal biometrics, photo evidence and real-time communication, shifting staff from after-the-fact data entry to on-the-spot case handling.

The M5 is built for public-safety and government fieldwork: about 242g and 13mm thin, 5.72-inch display, MTK octa-core 2.3GHz, 4GB+64GB (optional 6GB+128GB), Android 12; integrates online ID card verification, capacitive/optical fingerprint collection (FBI PIV/FAP certified, ≤0.25s), face recognition and QR scanning for identity-person consistency; 6000mAh battery for ~8h continuous use (>350h standby); IP67 sealing, 1.5m drop resistance and -20℃~60℃ operation; 4G + dual-band WiFi + BeiDou/GPS/GLONASS for real-time, location-trusted data.

OEM/ODM customization and system pre-loading are supported, meeting government Xinchuang requirements with reliable volume supply.

After the batch deployment, check-in verification upgraded from manual registration to ID + biometric verification with standardized collection; field visits are fully digitalized with real-time data aggregation, notably improving supervision efficiency.

The M5 + mobile verification combination also fits police patrol, border control, social-security authentication and financial scenarios requiring identity-person verification. SIZON supports OEM/ODM customization, Xinchuang adaptation, open SDK and system integration.
