A ultra-thin flexible durable radio frequency plastic of other substrate
identification device, such as cards, tags, badges, bracelets and labels
including at least one electronic element embedded therein and a hot or
cold lamination process for the manufacture of radio frequency
identification devices including a micro IC chip embedded therein. The
process results in a device having an overall thickness in the range of
0.005 inches to 0.033 inches with a surface suitable for receiving dye
sublimation printing--the variation in the device thickness across the
surface is less than 0.0005 inches. The hot lamination process of the
present invention results in an aesthetically pleasing device which can
be used as a sticker when adhesive is applied to the device. The
invention also relates to a plastic device in all shapes and sizes formed
in accordance with the hot lamination process of the present invention
and can withstand harsh chemicals and various pressures.
