Abstract: An improved structure for a USB flash drive includes an accommodating base, a circuit board, a sliding seat, a sliding key and a frame body. The circuit board having a connecting terminal on one end thereof and a fingerprint recognizer thereon is inserted into a bottom of the sliding seat for exposing the fingerprint recognizer to a surface of the sliding seat. When in operation, the sliding key is pushed forward to expose the fingerprint recognizer, and further forward movement of the sliding key will cause the sliding seat to move forward to expose the connecting terminal from the accommodating base. When not in operation, the sliding key is pulled rearward to cover the fingerprint recognizer. Further rearward movement of the sliding key will cause the sliding seat to move rearward to retract the connecting terminal in the accommodating base.
