1. Field of the Invention
The present invention relates to a seal and more particularly to a new seal comprising a base formed into a flat rectangular box. The base has a raised seal body in the center of its sealed wall. A cover is made for a first opening surface of the base. A resilient shackle made of wire is U-shaped with a first, second hook inwardly extending at two reversely bent end portions. The first, second hook is adapted to engage a first, second shoulder when inserted into the seal body. A chip is embedded in the base for radiating the radio frequency energy and receiving the identification code. Therefore, the object in this seal of the present invention is easy to be traced as the seal is coupled to a radio frequency identification device.
2. Prior Art
There are numerous types of seal assemblies known in the art and especially most of them are trying to improve the inner construction and avoid any opportunities of being opened. However, some seals are even intact but without any apparent evidences of tampering.
The main purpose of the present invention is to provide a new seal which has a chip embedded in the base. The chip is used as a reader for radiating the certain radio frequency energy to drive a transponder circuit sending out a specific identification code in its internal processor; in that case, the reader is allowed to identify the transponder and reaches the result of determining the position of the object in this seal of the present invention.
These and other features, aspects and advantages of the present invention will become apparent from the following description, claims and the accompanying embodiment shown in the drawing, which is briefly described below.

The resilient shackle 3 of the present invention is made of resilient wire having great thickness and elasticity to be bent into the U shape. The first, second hook 7 and 8 are inwardly extending at two reversely bent end portions. The width of the first, second hook 7 and 8 is slightly wider than the width of the space at two sides of the seal body 6 in the base 1 and also flange 12 is set on side walls 5 of the base 1 so that the hooks 7 and 8 are not easy to loose from the shoulders 9 and 10 after being pressed to thread through the aperture 13 of the base 1.
The chip 17 of the present invention is embedded in a suitable place of the sealed wall 4 of the base 1 and used as a reader for radiating the certain radio frequency energy to drive a transponder circuit sending out a specific identification code in its internal processor; in that case, the reader is allowed to identify the transponder and reaches the result of determining the position of the object in this seal.
The usage of the present invention is to place the first hook 7 of the resilient shackle 3 in the base 1 in advance (as shown in
