According to an exemplary embodiment of the invention, a USB flash memory device comprises a flash memory drive, an improved cap, a cap plug and a wire loop. The flash memory drive comprises a core unit and an outer shell structure. The cap comprises a substantially slab-shaped hollow structure with rounded edges and rounded corners, having an open end and a closed end, two opposing side walls, a top surface and a bottom surface. The cap is configured to substantially encase the entire flash memory drive through the open end, when the flash memory drive is in a closed configuration. The cap plug is configured to plug into the cap, when the flash memory drive is in an open configuration. The wire loop is configured to link the flash memory drive and the cap plug together in one location. ## Claims ### Claim 1 A Universal-Serial-Bus (USB) flash memory device comprising: a flash memory drive including an outer shell structure and a core unit assembled therein, the outer shell structure is formed by an upper housing and a lower housing; a cap plug including a top end block, a middle block and a plug end block, the middle block is configured to connect the top end block and the plug end block; a loop means for linking the flash memory drive and the cap plug together via two open slots on the outer shell housing structure of the flash memory drive and one hole on the top end block of the cap plug; and a cap configured to substantially encase the entire flash memory drive when the flash memory drive is in a closed configuration and configured to cover the cap plug when the flash memory drive in an open configuration. ### Claim 2 (depends on 1) The device of claim 1, the core unit comprises: a medium means for mechanically support and electrically connect electrical components with conducting pathways; a connector means for coupling to a host based on USB specification, the connector means is electrically and physically connected to the medium means; a flash memory controller mounted on the medium means; and at least one flash memory integrated circuit mounted on the medium means. ### Claim 3 (depends on 2) The device of claim 2, the core unit further comprises a fingerprint sensor included in a fingerprint processor mounted on the medium means. ### Claim 4 (depends on 3) The device of claim 3, wherein the fingerprint sensor is exposed through a finger print cut-out on the upper housing, which is also configured to provide an indent space for scanning fingerprints. ### Claim 5 (depends on 2) The device of claim 2, wherein the medium means comprises a print circuit board, a flex circuit or a lead frame. ### Claim 6 (depends on 2) The device of claim 2, wherein the connector means comprises a USB connector, a connector made of metal wrap and metal contact fingers configured on the medium means. ### Claim 7 (depends on 2) The device of claim 2, wherein the upper housing and the lower housing are coupled together with a seal means. ### Claim 8 (depends on 7) The device of claim 7, wherein the seal means comprises snap-in tabs and receptacle slots, and the medium means is configured with snap-in tab cut-outs to provide clearance for the snap-in tabs. ### Claim 9 (depends on 7) The device of claim 7, wherein the seal means comprises ultrasound welding. ### Claim 10 (depends on 2) The device of claim 2, wherein the loop means comprises a closed loop key chain. ### Claim 11 (depends on 2) The device of claim 2, wherein the cap comprises a substantially slab-shaped hollow structure with rounded edges and rounded corners, having an open end and a closed end, two opposing side walls, a top surface and a bottom surface, length of the top and bottom surfaces are so dimensioned that the cap substantially covers entire length of the USB flash memory drive in the closed configuration. ### Claim 12 (depends on 11) The device of claim 11, wherein the cap comprises a pair of slots located on the inner surface of each of the side walls configured to couple to a first pair of protrusion snap-in connectors located on the outer shell structure of the USB flash memory drive. ### Claim 13 (depends on 12) The device of claim 12, wherein the pair of slots is configured to couple to a second pair of protrusion snap-in connectors located on either side of the cap plug. ### Claim 14 (depends on 11) The device of claim 11, wherein the open end has a width substantially equal to width of the top end block of the cap plug and the closed end has a width substantially equal to width of the plug end block of the cap plug. ### Claim 15 (depends on 2) The device of claim 2, wherein the middle block has a narrower width than that of the top end block and that of the plug end block. ### Claim 16 (depends on 2) The device of claim 2, wherein the top end block and the plug end block have a substantially same thickness. ### Claim 17 A Universal-Serial-Bus (USB) flash memory device comprising: a flash memory drive including an outer shell structure and a core unit assembled therein, the outer shell structure is formed by an upper housing and a lower housing; a cap plug including a top end block, a middle block and a plug end block, the middle block is configured to connect the top end block and the plug end block; a wire loop for linking the flash memory drive and the cap plug together via two open slots on the outer shell housing structure of the flash memory drive and one hole on the top end block of the cap plug; and a cap configure to substantially encase the entire flash memory drive when the flash memory drive is in a closed configuration and configured to cover the cap plug when the flash memory drive in an open configuration. ### Claim 18 (depends on 17) The device of claim 17, wherein the cap comprises a substantially slab-shaped hollow structure with rounded edges and rounded corners, having an open end and a closed end, two opposing side walls, a top surface and a bottom surface, length of the top and bottom surfaces are so dimensioned that the cap substantially covers entire length of the USB flash memory drive in the closed configuration. ### Claim 19 (depends on 18) The device of claim 18, wherein the cap comprises a pair of slots located on inner surface of each of the side walls configured to couple to a first pair of protrusion snap-in connectors located on the outer shell structure of the USB flash memory drive. ### Claim 20 (depends on 19) The device of claim 19, wherein the pair of slots is configured to couple to a second pair of protrusion snap-in connectors located on either side of the cap plug.
