A flash-memory-drive card has an integrated slim Universal-Serial-Bus (USB) connector that fits into a standard USB socket. The slim USB connector has 4 metal contacts on a board that is encapsulated by upper and lower plastic cases. Components are mounted onto the board on the side opposite the metal contacts. A thinner portion of the plastic case forms a light window that allows a light-emitting diode on the board to shine through the case. The plastic cases can be bonded together ultrasonically or with adhesive or using snaps and groves. Supporting underside ribs in the lower plastic case opposite the metal contacts allow most of the card to be thinner than the spacing in the standard USB socket. Dividers between the metal contacts are formed between openings in the upper case. The dividers help to fill gaps between the slim USB connector and the standard USB socket.
