If telephone wiretapping is becoming a more difficult tool to use, at least in Italy, law enforcement can certainly not stop their investigation work, and in order to fight crime, in some cases they must resort to a more cumbersome and dangerous method, that is, for example, trying to infiltrate a criminal organization or a terrorist cell, in order to try and gather in first person information that might be collected with listening bugs.
In order to carry out this kind of operations, one of the most useful instruments that surveillance technology can provide is certainly an invisible earpiece, that is, a miniaturized transmitter that, once placed inside the ear canal, can be used to listen to what is happening around its wearer, and to send him information and instructions from a remote location, in order to guide him in his intelligence gathering operation.
Invisible earpieces conceal, in their tiny size, a micro transmitter which can be connected via Bluetooth to a radio transmitting or GSM watch, that is, something that looks like your ordinary wristwatch but on the inside contains a radio transmitter or a SIM card just like the ones we use on mobile phones. Through this set, the information gathered through the earpiece can be sent via radio to a listener hidden somewhere within a range of a couple of kilometers, or by using the GSM phone network, it can be sent to any corner of the world towards a preset phone number, starting the transmission operation with the simple click of a button.
