RFID encoder and verifier

An RFID encoder (202) is used in conjunction with a barcode print and apply system. The RFID encoder (202) utilises information obtained from a data stream from a host computer (102), from a corresponding barcode label, or other source to program an RFID label. The programmed label can then be applied with an integrated applicator or an external applicator. The RFID encoder (202) can also verify that an RFID tag or label has been properly encoded and has the same content as the corresponding barcode label. The RFID encoder (202) can further verify that the barcode has been properly printed. If both barcode and RFID tag contain the correct data, both types of labels are attached to a package, enabling the package to be read optically and with radio frequency signals.
