A USB device in which all of the devices ICs are located on a lower surface of a PCB (i.e., opposite to the metal contacts) to minimize the device's thickness, and at least one of the ICs is positioned on a relatively narrow portion of the USB plug to minimize the device's length. A card-like carrier for protecting the USB device when not in use includes a frame-like base portion having peripheral walls surrounding a relatively wide main chamber, and an end portion that is attached to the base portion and includes end walls that define a relatively narrow slot communicating with the main chamber. The USB device plug structure is inserted through the main chamber into the slot until a front edge of the handle structure abuts the end walls, and then the device is rotated downward into the main chamber.
