Abstract
A tag reading apparatus comprises a passage that is configured to receive an RFID-tagged article that is to be registered in a transaction. The passage has an inlet end and an outlet end separated from each other in a first direction and width in a second direction. An antenna is in the passage at a position between the inlet and outlet ends in the first direction. An RFID reader is provided to read an RFID tag according to a response wave from the RFID tag received via the antenna. A controller is configured to identify the RFID-tagged article as being in the transaction according to a change in the response wave (such as a phase difference or intensity) corresponding to a movement of the RFID-tagged article from the inlet end to the outlet end.
Claims20
A tag reading apparatus, comprising:
- a passage through which a container storing an RFID-tagged article to be registered in a transaction can pass, the passage having an inlet end and an outlet end separated from each other in a first direction and a width in a second direction perpendicular to the first direction;
- a roof by which an opening above the passage is at least partially covered and including a material capable of absorbing a radio wave;
- an antenna in the passage at a position between the inlet and outlet ends in the first direction;
- an RFID reader;
- and
- a controller configured to identify the RFID-tagged article as being in the transaction according to a change in a response wave received by the RFID reader from an RFID tag of the RFID-tagged article via the antenna, corresponding to a movement of the RFID-tagged article from the inlet end to the outlet end.
