Sample identification utilizing RFID tags
First Claim
1. A radio frequency identification (RFID) reader, comprising:
- a body including a proximal end region;
an RF transceiver antenna mounted to the body at the proximal end region; and
an RF shield mounted to the body and extending out from the body beyond the proximal end region to an open end of the RF shield, the RF shield defining an interior space between the body and the open end, wherein the antenna is surrounded by the RF shield.

Abstract
A radio frequency identification (RFID) reader may include a body including a proximal end region, an RF transceiver antenna mounted to the body at the proximal end region, and an RF shield mounted to the body and extending beyond the proximal end region. The RF shield defines an interior space between the body and an open end of the RF shield, and surrounds the antenna. Alternatively, or additionally, a holder of sample containers may provide an RF shield. The reader may be moved into position over a sample container to enable communication between the antenna and an RFID tag associated with the sample container. The RF shield provides isolation from neighboring sample containers.
