Abstract
Methods and apparatus for metering printed media are disclosed. A disclosed example apparatus comprises a first radio frequency identification (RFID) tag to adhere to a first leaflet of a printed media at a first location; a second RFID tag to adhere to a second leaflet of the printed media at a second location of the second leaflet, the first and second locations being substantially a same location; and a first RFID absorber to adhere to a third leaflet of the printed media such that, when the printed media is positioned to expose the first and the third leaflets, the second RFID tag is inactive, and such that, when the printed media is positioned to expose the second and the third leaflets, the first RFID tag is inactive.
