In case you’ve been looking for a rather discrete way of spying someone, check out the Digital Card Calculator Camera. As the name suggests, this is a 2-in-1 gadget, it can work as a calculator and also as a digital camera in disguise.

The camera can hold 32 images on high resolution - 1280×960 - or 117 images at a lower quality of 640×480 pixels. It uses the “old” USB interface also known as 1.1, but since you won’t be transferring big files there won’t be a problem with speed transfers.

The spy camera calculator costs $69.99 and features a whopping 300k CMOS sensor with 8k of memory.

PS - The scenarios used to actually spy someone with this camera can be pretty frustrating.
