1．Introduction

BioFlash Disk is a perfect integration of movable memory and biometric

identification technology. As the fingerprint of human being features its exclusiveness

and doesn’t need to be remembered, the user of the device can replace the passwords

with his own fingerprint and, with incorporation of authentication and encryption

technology, the data in the BioFlash Disk or in the computer can be safely protected.

Up to now, the flash disk has become the device that must be configured. With the

continuous capacity increase of a single granule of the flash memory chip, the flash

disk has been developed to be a device playing more important role for data saving

and backup from the early-stage when it was only a substitute of floppy. Thus the

security of the data saved in the flash disk is increasingly concerned!

This product, integrating the new-generation slide-type fingerprint reader and world

top-class algorithm for fingerprint identification and incorporating the high-strength

AES-256 encryption algorithm, can slit a fingerprint encrypted partition in the flash

disk that is used to save the private data of the user. In addition, you can use it to

encrypt the data files in your computer.

Eliminating the inconvenience of memorization and inputting the long passwords,

the privately used BioFlash Disk can bring you both facility and security.

Conforming fingerprint information needs to be acquired by the user for both

authentication and registration. Correct finger sliding for acquiring conforming

fingerprint can ensure the successful identification. The following instructions shall be

followed:

Allow the sensor to be as plane as possible and the finger to be vertical to the

sensor

Keep your finger sliding along one direction in the guide slot, without

reciprocating

Keep the sliding speed even

Apply a certain force on your finger whole sliding on the sensor so as to ensure

good contact between the finger and the sensor.

Note: Keep your finger clean. Wet or dirty finger will affect the acquisition of

fingerprint information or may damage the sensor!

Correct way

Allow the first knuckle

to get close to the

sensor.

Place the finger evenly

onto the guide slot

Allow the finger in the guide

slot to slide steadily and

smoothly from the first

knuckle to the finger tip, keep

the finger well contacting the

sensor.

Keep sliding till the sensor

is exposed.


Incorrect way

Finger is bended.

Finger leaves the

surface of the senor in

the course of sliding.

Use the finger tip not the pad

of finger.

In the course of sliding,

the body (like the finger)

contacts the metal head of

USB or port.

Please do not use the sharp objects, particularly the metal objects, to scratch the

surface of the sensor.

As the water or dirt on the sensor surface can affect its performance, please keep

the surface clean with soft rags.
