Abstract: An RFID electronic seal includes a head and a strap. A through-hole extends from a first side through a second side of the head. The strap includes an end extending from the first side of the head. A tag is embedded in the head or the strap. A signal-transmitting line is embedded in at least one of the head and the strap and extends from the tag. The strap is extendable through the through-hole of the head along a tightening direction, forming a tightening space, with an engaging member on the strap engaging with another engaging member on the head to prevent the strap from moving in an unfastening direction. The electronic seal can be used in a tracking system that allows a cargo or goods owner to notice breakage of the electronic seal in real time.

Abstract: A method for embedding a tag in an object includes placing a tag in a mold defining a cavity for forming an object, holding the tag on a face delimiting the cavity, and forming the object in the cavity, with the tag being embedded in the object. The tag includes an inner layer with an outer face, an outer layer formed on the outer face of the inner layer, and an integrated circuit mounted on the outer face of the inner layer and covered and thus protected by the outer layer, with an antenna device being electrically coupled to the integrated circuit, and with the antenna device being also covered and thus protected by the outer layer. The outer layer is made of non-metal material to allow transmission of signals.
