ZOIOT NK-842 Feature And Application：

1.Hardware Independent Fingerprint Management
The fingerprint USB flash drive realizes all fingerprint operations via physical side buttons without mobile software: double-click the button to enroll new fingerprints (blue light flicker for fingerprint input, repeat pressing the same finger 5 times to finish registration); triple-click the button to clear all stored fingerprints (red light flicker, verify existing fingerprint twice to erase records, original stored files will not be deleted at all). This offline hardware control avoids data upload risks caused by third-party apps.

2.Exclusive One-Time Temporary Sharing Mode
Equipped with a matched reset key tool, this fingerprint encrypted USB flash drive supports safe temporary lending. Insert the reset key together with the USB drive into any device, pull out the reset key after system recognition to activate temporary access mode. Under this mode, others can normally read and write all files, but cannot add or delete any administrator fingerprints. Once the USB drive is unplugged, the temporary access permission will be invalid automatically, and fingerprint verification is required again for next insertion, effectively preventing unauthorized permanent access.

3.Universal Dual Interface Cross-Device Compatibility
The retractable dual-port design of NK-842 fingerprint USB flash drive breaks the limitation of single interface storage devices. Users can directly transfer photos, contracts, videos and archives between mobile phones and computers without adapters. The USB3.2 high-speed protocol greatly shortens the waiting time for large file transmission, which is far more efficient than traditional USB2.0 encrypted flash drives.

4.Full-Disk Hardware Encryption & Portable Metal Body
Adopting military-grade full-disk encryption algorithm, the fingerprint encrypted USB flash drive locks all internal storage space. If the device is lost or stolen, outsiders cannot access any data without authorized fingerprints. The compact metal body is lightweight enough to put into pockets, wallets or keychains, ideal for carrying on business trips and daily commuting.
