The invention relates to a molded plastic container having a radio frequency identification (RFID) tag and a method for manufacturing the same. The method mainly comprises the following steps: (a) providing a plastic container preform; (b) placing the container preform in a blow mold; (c) blowing the plastic preform within the blow mold to form a hollow plastic container; (d) placing the RFID tag on an actuator external to the blow mold; and (e) prior to the step (c), actuating the actuator and placing the RFID tag within the blow mold so that molding the tag into an external surface of the container during the step (c). The step (e) includes mounting the tag on a closed end of the plastic preform, and moulding the tag into a base of the container hereafter; in the step (e), moulding the tag into a bag in the base of the container, seeing the tag through an opening facing the bag, placing the tag in a plastic shell with a wall, and the container, in the step (c), surrounding the shell and being blowed toward the wall to form the opening.
