A device supports an electronic tag to extending neck of a bottle where the extending neck includes a perimetrical undercut thereabout. The device includes a housing formed of a pair of matable housing portions for attachment about the neck of the bottle. At least one of the housing portions supports an electronic tag. A rim is formed on each housing portion. The rim portions are mutually engageable and align to form a perimetrical rim. The perimetrical rim of the housing is seatable in the undercut of the neck to prevent longitudinal movement of the mated housing portions along the neck.
