The toolkit of the perfect spy has changed over time, sporting the latest development in miniature technology, be it a fountain pen which hides a gun like in James Bond movies, a micro transmitter concealed in the buckle of what looks like a normal belt, or in modern times, an audio digital micro recorder that actually looks like, for example, the key holder of your car.
Secret agents have always been on the cutting edge of technology, because in order to steal secrets, one must be as discreet and invisible as it gets, and miniature audio technology is the perfect companion for this kind of jobs.
In current times, a recording device can be as small as a 2 Euro coin, and can house a memory card up to 32 Gigabytes, which means that, thanks to its miniature size microphone, it can store hours and hours of conversations and sounds without being noticed.
After all, who would think that a pen, a key ring, a fountain pen, a USB drive or a cigarette lighter, while they are perfectly working as such, are also actually concealing a miniature recording equipment, highly sensitive, which is capable of picking up sounds with extreme clarity within a range of up to 10 meters?
The modern secret agent has at his disposal a wide range of tools to record sounds, conversations, to shoot video footage and to take discreet snapshots, as well as optical fiber cables which can be used as hidden cameras, or even mobile phones that secretly transmit their conversations to a third party listener in real time.
All these tools share a common characteristic: they are almost invisible, and their real purpose is not immediately obvious, which makes for a perfect covert operation!
