Container seal with radio frequency identification tag, and method of making same

A closure assembly for a container defining an interior volume, an opening into said interior volume, and a sealing surface bordering said opening, said closure assembly comprising:

• a closure, including an end wall with an end wall inner surface, said closure being attachable over a container opening for closing thereof;
• an inner seal including a first surface for engagement with a container sealing surface, and a second, opposed surface for engagement with one of a backing liner, a facing liner, an induction seal liner, and a glued-in closure liner;
• and
• a radio frequency identification tag including a microprocessor electrically coupled with an antenna for receiving, storing, and transmitting selected digitized information;
• wherein said inner seal can minimize migration of fluids between a container interior volume and an exterior of a container when said inner seal is engaged with a container sealing surface;
• and
• wherein said radio frequency identification tag can be included in said closure assembly within a container interior volume or external to a container, or can be incorporated into said inner seal, without said closure assembly electromagnetically interfering with said receiving, storing, or transmitting of said digitized information.
