An encoder device for encoding a series of radio frequency identification
tags supported by media includes a media path, at least two antennae, at
least one transceiver, and a controller. Media and radio frequency
identification tags are advanced along the media path. The at least two
antennae are spaced from each other and each of the antennae are
positioned along the media path adjacent to at least one of the radio
frequency identification tags. The at least one transceiver is configured
to communicate with the antennae. The controller is configured to
communicate individually with each of the respective radio frequency
identification tags positioned adjacent the antennae using the
transceiver and the antennae.
