Short range agent communications (SRAC) are one-way or two-way short-range wireless communications used for intelligence purposes. This communications technology became possible with the arrival of the transistor and small scale integrated circuits. In the late 2000s computer WiFi technology and USB Flash Drives had evolved into technologies that ordinary people can buy – yet can be used in a similar way to SRAC systems.[1]
SRAC devices were adopted by Western intelligence agencies during the Cold War in the 1960s, but Eastern Bloc nations possessed and used similar technologies.[1] The devices are miniature to ease concealment, and are capable of transmitting encrypted data.
