Abstract
Labels that have radio frequency identification (RFID) tags embedded within them may include a removable electromagnetic shield that is removed only for the next tag to be processed, so that only that tag will be detected by an RFID reader. In some embodiments such processing includes printing the labels. Different embodiments may use single-sided or double-sided shielding.
