▎ 摘　　要

NOVELTY - The tag has a chip (3) fixedly connected with a first metal layer (4) by conductive adhesive. The first metal layer is fixedly arranged with a second metal layer (62). A glue-free region is arranged on an outer side of glue (2) in a frequency point group, where the glue is removable glue, thickness of the removable glue is 10-30 microns, and the first and second metal layers are made of conductive material, copper, silver paste or graphene. USE - Multi-functional wireless radio frequency identification tag for different frequency bands in retail. Uses include but are not limited to unmanned convenience store, book management, medical health, aviation, logistics and traffic fields. ADVANTAGE - The tag is convenient to process, and improves product competitiveness. The tag realizes label multi-frequency point performance and extends an application range of a product. DESCRIPTION OF DRAWING(S) - The drawing shows a side sectional view of a multi-functional wireless radio frequency identification tag.
