First Claim
Patent Images
1. A RFID printer, comprising:
- a RFID reader/writer;
an index sensor configured to detect a leading edge of a RFID record member, the RFID record member including one or more RFID transponders;
an antenna configured to emit a RF field and coupled to and cooperating with the RFID reader/writer to read and/or write to a RFID transponder;
a printing system having a print head and a drive mechanism to drive a web of RFID record members past the print head for printing data thereon;
a memory; and
a processor, the processor coupled to the memory, the index sensor, the printing system, and to the RFID reader/writer and operable to encode and print on the RFID record member as the web continues in motion, the processor configured to perform the steps of;
determining if the RF field is capable of encoding the RFID transponder at a selected continuous web speed;
if the selected continuous web speed is too high to encode the RFID transponder, determining a continuous lower web speed at which to encode the RFID transponder; and
adjusting the web speed to the determined continuous web speed to encode the RFID transponder.

Abstract
A system and method for encoding and printing RFID record members with a continuous moving web is provided. In particular, a printer such as a RFID printer is capable of encoding an inlay or multiple inlays within a record member while the web is continuously moving. While a record member is being encoded on a moving web, the record member may be printed upon when a leading edge of a record member reaches the print position.
