Various embodiments include, for example, a memory-card holder including a one-piece, unitary tray formed entirely from a bio-degradable material. The tray has a cover portion and a bottom portion formed therein. At least one of the cover portion and the bottom portion has an indentation to accept a digital memory-card. The tray further includes a protrusion area on at least three sides projecting outward from and substantially parallel to the cover portion and the bottom portion. A hinge is integrally formed into the unitary tray and between the cover portion and the bottom portion. The hinge is arranged to allow the cover portion to fold over the bottom portion of the tray. A closure tab and an insertion slot are formed on distal, opposing ends of the tray and arranged to latch the cover portion and the bottom portion to one another. Other devices, apparatuses, and arrangements are described.

A card storage apparatus includes a box body. At least one side of the box body is provided with an accommodating slot, a main control panel, a battery and a sound generator are installed in the accommodating slot. The main control panel is provided with a Bluetooth main control chip and an antenna module, the Bluetooth main control chip is electrically connected to the battery, the sound generator and the antenna module, respectively. The main control panel, the battery and the sound generator are staggered. The card storage apparatus is novel in structure, and functional modules of a Bluetooth tracker are staggered and dispersed, so that a surface space of the card storage apparatus is fully utilized, and the portability thereof is improved.
