Abstract
Embodiments are directed to sequential encoding for RFID tags. An encoding line transports an RFID tag from the reading zone of a first reader to the reading zone of a second reader. The first reader communicates with the tag, writes a portion of an identifier to the tag, and sends a tag write status to the second reader. The second reader, situated after the first reader, communicates with the tag, receives the tag write status from the first reader, then determines a remaining portion of the identifier to be written to the tag based on the tag write status. The second reader then attempts to write the remaining portion to the tag. If the attempt fails, the second reader initiates an error-handling procedure.
