The portable data carrier (1) has a carrier layer (2) whose main surface is accommodated with electronic circuits (501,502). A removable region (6) having an edge portion (601) is formed in a remaining portion of the carrier layer, such that the electronic circuit is deactivated when the removable region is separated by a user. A notch formed on a surface opposite to main surface of carrier layer is interrupted at locations where components of the electronic circuit are located. Independent claims are included for the following: (1) a packaging unit for packaging food product; and (2) a method for manufacturing portable data carrier. |
