Abstract
A system to determine the placement of multiple RFID tags uses multiple antennae. The RF communication (or NFC) includes read and/or read/write communication with the RFID tags.
Claims24
A system to determine spatial placement of one or more radio-frequency identification (RFID) tags using multiplexed antennae for Near Field Communication (NFC), the system comprising:
- a radio-frequency (RF) reader circuit configured to establish NFC through radio-frequency identification (RFID) with a first radio-frequency identification (RFID) tag;
- an antenna-selecting module configured to selectively establish electrical coupling to receive information through a first antenna having a first location or through a second antenna having a second location;
- and
- a controller configured to determine placement of one or more RFID tags by controlling the antenna-selecting module such that the controller is configured to determine whether the first RFID tag is closer to the first location or the second location.

A computer-implemented method for determining spatial placement of one or more radio-frequency identification (RFID) tags using multiplexed antennae for Near Field Communication (NFC), the method comprising:
- establishing NFC with a first radio-frequency identification (RFID) tag by controlling an antenna-matching network;
- selectively establishing electrical coupling such that information is received from the first RFID tag through a first antenna having a first location or a second antenna having a second location;
- and
- determining placement of the first RFID tag by selectively enabling NFC through the first antenna and the second antenna, wherein placement determination includes determining whether the first RFID tag is closer to the first location or the second location.
