One of the least used products in the spy pen market is the digital image spy pen.  It sole purpose is to capture single snap shot images of its surrounding area, unlike other models it doesn’t contain any hardware designed to capture audio or video tracks and because of this finds its implementation and use somewhat limited.

However when the situation arises where it can perform its role it is exceedingly good.
Many people find it a handy devise to carry around on their person; it can be whipped out at any given time to get that all-important shot.  Its disguise allows it to be taken into areas where cameras are not allowed and has allowed its user to take photographs of prototype products and private documents.
