A system, method and computer program product for enabling a user to detect nearby RFID tags and identify nearby RFID readers to enhance user privacy. A portable RFID reader scans for nearby tags, and a universal RFID tag detects nearby readers. The invention can alert the user of nearby RFID tags or readers, unless the user has disabled the alerting feature or unless a particular tag or reader is already known to the user and has been deemed allowable. A memory includes editable lists of allowable tags and readers. Exemplary alerts include outputs from a sound emitter, a vibrator, a light, or a display readout. The invention thus prevents surreptitious identification and tracking of a user and a user's possessions. The invention may be integrated into items typically carried by users so that the detection and alerting may be performed without outward indication.
