Abstract
Embodiments include methods and apparatus for detecting proximity of an electronic article surveillance (EAS) tag. A proximity detection system (e.g., a radio frequency identification (RFID) tag reader) detects a presence of an object within a first area. In response to detecting the proximity of the object, an EAS tag reader alters characteristics of an EAS tag detection signal that is produced by the EAS tag reader in order to detect an EAS tag within range of the EAS tag reader.
