1. A multi-document read-write device comprising:
- a slot configured to receive a plurality of RFID tagged documents, wherein the slot is formed from no-conductive walls;
a chamber disposed within a set of conductive chamber walls, the chamber walls surrounding said slot;
an angled stop wall located at the end of the slot, the angled stop wall configured to introduce a positional offset to each RFID tagged document that is inserted into the slot; and
one or more antennas positioned in the chamber and configured to generate an RF field for interfacing with RFID tags disposed within the slot.

Abstract
A multi-document read-write station provides the ability to read/write to a stack of Radio Frequency Identification (RFID) tags within a small area. Specifically, the station provides the ability to read from and write to a tall stack of RFID tagged sheets with the RFID tags stacked one on top of the other. The station and capability described herein is the result of and comprises several components including a closed chamber comprising a document slot, an antenna system, and a power management system.

14. A method for reading and writing information from multiple RFID enabled documents, the method comprising:
-
receiving a plurality of RFID tagged documents in a slot formed in an multi-document read-write device, wherein the multi-document read-write device comprises a set of conductive chamber walls surrounding said slot, an angled stop wall located at the end of the slot, a transmit antenna configured to generate an RF field for interfacing with RFID tags disposed within the slot, and a receive antenna configured to receive backscattered signals from RFID tags disposed within the slot; transmitting an RFID interrogation signal via the transmit antenna to the RFID tags disposed within the slot; and receiving at the receive antenna backscattered signals from the RFID tags disposed within the slot. - View Dependent Claims (15, 16, 17, 18, 19, 20)
