Systems and methods involving transferrable identification tags are provided. In one embodiment, a system includes a delivery device, a container, and a tag coupled to the container and configured to store information related to contents of the container. The delivery device is engageable with the tag and at least a portion of the contents of the container are transferrable from the container to the delivery device following its engagement with the tag. The tag is removable from the container in engagement with the delivery device such that the delivery device carries the tag following its removal. In one form, a frangible member is coupled to and extends between the tag and the container, and the tag is removable from the container by the delivery device upon breakage of the frangible member. Other embodiments include unique methods, systems, kits, assemblies, equipment, and/or apparatus which involve transferrable identification tags.
