Cargo containers are an attractive target for criminal organisations because of the value of the goods they carry, and due to the fact that they can be used as a trojan horse, i.e. as a vehicle for introducing weapons or explosives in a country. Electronic cargo seals (e-seals) using Radio-frequency Identification (RFID) technology are the most effective devices for securing containers, but they are also expensive, and this is why most of traders today still prefer to adopt more traditional solutions like the bolt seal and single-loop cable seal.
