Fingerprint & Password Management: After connecting the fingerprint USB drive, you can enroll or manage fingerprint information within the app, and also set an independent access password (as a backup option when fingerprint recognition fails). All credentials are stored in the hardware chip, with no data retained on your phone. One-Touch Unlock, Native Access: After successful fingerprint verification, the system will automatically unlock the encrypted partition of the USB drive and directly jump to Apple's native "Files" app. You can browse, edit, or transfer files just like using a regular USB drive in this familiar interface, ensuring smooth operation with no learning curve. Plug-Out & Lock, Security On-the-Go: Once the USB drive is unplugged, the encrypted partition is automatically hidden, eliminating privacy concerns. [E-Ink Screen: Direct Image Projection, Restoring Paper Texture] Deeply optimized for the display characteristics of electronic ink screens to ensure images from your phone look perfect on e-ink devices. Simple Image Projection Experience: Select images directly from your phone's photo album and send them to a connected e-ink device (such as an e-reader or e-ink monitor) with one click. Supports batch selection, allowing you to quickly create a personal gallery. E-Ink Mode Optimization: During transmission, images are automatically processed with a grayscale algorithm to enhance display clarity on low-refresh-rate screens, reduce ghosting caused by dithering, and simulate the texture of real paper printing. Offline Viewing: Once images are transferred to the local storage of the e-ink device, you can browse them anytime even after disconnecting from your phone, making it ideal for use as an art gallery or for children's coloring activity displays.
