A system and method for configuring Radio Frequency Identification (RFID) read and write power levels includes an RFID module that generates RF signals, a digital step attenuator that attenuates RF signals, an antenna that transmits attenuated RF signals, and an RF shield that isolates the antenna from an RFID label supply roll. A floor read power is determined by iteratively interrogating an RFID label while decreasing the RF signal power until the label fails to respond to the interrogation. A ceiling read power is determined by iteratively interrogating the RFID label while increasing the RF signal power until multiple labels respond to the interrogation. The read power level is set between the floor read power and the ceiling read power. The write power level is determined by iteratively attempting to program the RFID module while increasing the write power from the read power level until successfully written.

RFID read and write power setting system and method

A high speed tabletop and industrial printer is disclosed with integrated high speed RFID encoding and verification at the same time. The industrial printer simultaneously prints on and electronically encodes/verifies RFID labels, tags, and/or stickers attached to a continuous web. The industrial printer comprises a lighted sensor array for indexing the printing to the RFID tags; and a cutter powered from the industrial printer for cutting the web that the RFID tags are disposed on. The industrial printer comprises two RFID reader/writers that are individually controlled. Specifically, one of the RFID reader/writers comprises the ability to electronically encode the RFID tags while the web is moving; and the second RFID reader/writer uses an additional RFID module and antenna on the printer for verifying the data encoded to the RFID tags.

The printer provides for successive writes to various memory blocks and optimizes the communication sequence between the interrogator and tag.
