Turn a compatible TF/microSD card into portable storage with the ZOIOT NK-827 fingerprint encrypted card reader. Its fingerprint sensor, USB-A and USB-C connectors, and companion app bring card access and encryption management together in a compact gunmetal gray body.
- Fingerprint access control: Enroll your fingerprint through the companion app and use the built-in sensor to unlock a configured card. Follow the supplied setup instructions before storing important files.
- USB-A and USB-C connections: Use the connector appropriate to your compatible computer, phone or tablet. Device and operating-system support determine which functions are available.
- Reuse compatible TF cards: The concealed TF/microSD slot accepts a separate card; supplier specifications list support for cards up to 1TB. The reader provides access control rather than built-in storage.
- Companion app management: The supplied images show Finger Card app setup, card encryption and decryption controls. The supplier lists iOS, macOS, Android and Windows support; mobile setup requires a compatible app and device.
- Compact everyday carry: The 16g reader has protective connector caps and a small hanging loop. Both USB connections are rated by the supplier at a theoretical maximum of 480Mbps; actual transfer speed depends on the card and connected device.

The MOQ is very low and shipping is completely transparent. The DDP pricing helped us avoid customs hassle and gave us peace of mind. TenDollarStore made it easy to source different SKUs at once. For any new reseller in Europe, this is a trustworthy wholesale partner.
