1. A system for reading RFID tags or labels on one or more items in a shopping cart or basket, comprising:
a chamber with a processor, the chamber being sized and configured to receive the shopping cart, basket, or combinations thereof, the chamber comprising:
at least one portal sized and configured to allow for introduction of the shopping cart, basket, or combinations thereof into the chamber or removal of the shopping cart, basket, or combinations thereof from the chamber, and,
at least one closure associated with each of the at least one portal and configured to be moved between
an open condition allowing for introduction of the shopping cart, basket, or combinations thereof into the chamber via the portal and/or removal of the shopping cart, basket, or combinations thereof from the chamber via the portal, and
a closed condition covering the at least one portal to prevent introduction of the shopping cart, basket, or combinations thereof into the chamber via the portal and/or removal of the shopping cart, basket, or combinations thereof from the chamber via the portal;
an RFID reader;
at least one antenna coupled to the RFID reader, associated with an interior of the chamber, and oriented to send signals to and receive signals from RFID tags or labels on the one or more items in the shopping cart, basket, or combinations thereof within the chamber,
wherein the chamber and the closure are configured to prevent signals sent to and from the RFID tags or labels on the one or more items in the shopping cart, basket, or combinations thereof within the chamber from exiting the chamber,
wherein the processor is configured to determine a presence or absence of the shopping cart or the basket at a target location within the chamber based on detection of the shopping cart or the basket using at least one infrared sensor disposed within the chamber, wherein the processor is configured to trigger the RFID reader to generate a radio frequency field after the at least one closure has been placed in a closed condition and upon determination of the presence of the shopping cart or the basket at the target location within the chamber using the at least one infrared sensor disposed within the chamber; and
a transport mechanism configured to move the shopping cart or basket through the radio frequency field at a controlled rate while the at least one closure is in a closed condition, the controlled rate having varying speeds and being in different directions.
