1. A high density read chamber for scanning a plurality of RFID tagged items, comprising:
an enclosure including an upper surface, a lower surface, and a sidewall extending between the upper and lower surfaces to define an interior of the enclosure, wherein at least a portion of at least one of the upper surface, the lower surface, and the sidewall includes a signal-reflective material facing the interior of the enclosure;
an access associated with at least one of the upper surface, the lower surface, and the sidewall and configured to be at least partially opened to access the interior of the enclosure from an outside location;
a first and second antennae positioned side-by-side on a same surface within the interior of the enclosure such that at least one antenna is used for both emitting a signal for encoding one or more of the plurality of RFID tagged items and emitting a scanning signal within the interior of the enclosure for scanning one or more of the plurality of RFID tagged items, wherein the at least one antenna of the first and second antennae is a dipole-type antenna; and
an RFID reader associated with the first and second antennae and configured to:
receive signals from and/or transmit signals to the first and second antennae,
store data scanned in the chamber,
send encoding information to the at least one antenna of the first and second antennae, and
end a scanning procedure.
