RFID tag communication device
According to an embodiment, a wireless tag communication device includes a first antenna that emits radio waves towards a first region of a conveyance path for wireless tags and a second antenna that emits radio waves towards a second region of the conveyance path on downstream of the first region along the conveyance path. A shield prevents the radio waves emitted from the first antenna from reaching a first portion of the first region while permitting the radio waves to reach a second portion of the first region. A controller is configured to select a tag ID read via the first antenna as a target tag ID, designate the target tag ID by communication via the second antenna, and then write tag information via the second antenna to the wireless tag corresponding to the designated target tag ID.
Multi-antenna RFID printer
A radio frequency identification (RFID) printer device for electronically encoding and verifying RFID labels, the RFID printer device comprising a thermal printhead, a platen roller, a first RFID antenna configured upstream from the thermal printhead and the platen roller, a second RFID antenna configured downstream from the first RFID antenna, a memory device having executable instructions stored therein, and one or more processors communicatively coupled to the memory, the one or more processors, in response to the executable instructions, configured to transmit data via the first RFID antenna, wherein the data is encoded to one or more RFID tags associated with respective one or more RFID labels during a first RFID communication window, and receive and transmit data via the second RFID antenna to verify the encoded data during a second RFID communication window.
Inline testing of RFID inlays
This disclosure relates to inline testing of RFID inlays. A test system includes a test interface without moving parts and a marking device. The test interface an array of antennas, a radio frequency identification (RFID) reader to interrogate RFID inlays to be tested; and a circuit configured to selectively connect the RFID reader to the antenna in the array of antenna. The test interface performs a primary scan of all of the RFID inlays to be tested and, when not all of the RFID inlays respond, a secondary scan to determine which of the RFID inlays failed to respond. The marking devices mark any of the identified RFID inlays that failed to respond.
Wireless communication device
A wireless communication device includes a conveyance portion, a sensor, and a communication portion, and conveys a long backing sheet, a plurality of labels, each provided with a wireless tag, being adhered with intervals in a lengthwise direction of the backing sheet. The wireless communication device detects, by the sensor, an end portion on an upstream side of the label including a wireless tag adhered on the backing sheet, while conveying the backing sheet in a conveyance direction by the conveyance portion, and performs a wireless communication with a target label when the backing sheet is conveyed by a predetermined amount in the conveyance direction. The predetermined amount is decided based on a communication state, between the communication portion and the wireless tag, detected at each of positions when the backing sheet is sequentially conveyed to a plurality of positions in the conveyance direction.
