  • Seal having an IC tag and method of attaching the same
    Patent number: 7876221
    Abstract: The seal having an IC tag is to be attached to cover a bordering part between the cover and main body of a container. The seal has a base member serving as a support, an antenna provided on one surface of the base member and having a slit, an IC chip connected to the antenna and provided on the antenna, and an adhesive layer provided on that surface of the base-member on which the antenna and the IC chip are provided.
