Claim:
1. An RFID registration apparatus for registering units comprising RFID tags, the registration apparatus comprising: a detector space comprising a top, a bottom and four vertical sides including a first vertical side and a second vertical side, wherein the second vertical side is opposite the first vertical side, a receiver configured to receive a number of units and to be placed inside the detector space, a first antenna configured to read the RFID tags by emitting and receiving electromagnetic radiation within a first frequency range, the first antenna is at the top of the detector space, and at least four plane reflector surfaces, including a first primary reflector surface, a first secondary reflector surface, a second primary reflector surface and a second secondary reflector surface, each reflector surface is configured to reflect the electromagnetic radiation within the first frequency range, wherein the first primary reflector surface is positioned to intersect the first vertical side and the top of the detector space, and the first secondary reflector surface is positioned to intersect the first vertical side and the bottom of the detector space, and the second primary reflector surface is positioned to intersect the second vertical side and the top of the detector space, and the second secondary reflector surface is positioned to intersect the second vertical side and the bottom of the detector space, wherein the first primary reflector surface and the first secondary reflector surface span a first angle facing the detector space, and the second primary reflector surface and the second secondary reflector surface span a second angle facing the detector space, wherein the first angle and the second angle are in the range of 70-140 degrees.
