A Norwegian hospital is outfitting all newborn babies with Anti-Theft Alarms. The alarms consist of a small chip placed on the baby’s ankle bracelet and it is paired with a matching chip on the mother’s bracelet.
If the two chips are separated by more than a certain distance, an alarm goes off. If the baby’s bracelet is removed without authorization, the whole hospital goes into lockdown mode with the elevators stopping and the doors locking. The alarms are meant to prevent both kidnappings and baby mixups.
