Smart labels, often called labels, are made of layers of thin sheets of various types
of materials with an RFID inlay embedded within those layers. These layers usually
include the linear or carrier sheet, linear release coating, inlay adhesive, tag
inlay, face stock adhesive, label material, and label topcoat. Figure 3-4 shows a
typical smart label. Barcodes and textual information are usually printed on the
smart label material in addition to an identifying number that is encoded into
the embedded RFID inlay. The smart labels use either a direct thermal or thermal
transfer printing method
