A method for correlating a product identifier of a product and an RF tag identification code after the step of printing visual representation of a product identifier onto a product label, and reading the visual representation of the product identifier.

An image forming device includes a wireless tag communication device and a controller. The wireless tag communication device is configured to acquire identification information to identify a wireless tag from the wireless tag provided in a sheet. The controller is configured to acquire dispensing information required to write to the wireless tag and perform a warning process by using the acquired dispensing information and the acquired identification information, upon the dispensing condition not being satisfied.

A desktop plastic card printer that is configured to allow installation of a smart card cartridge within an interior space of the printer housing through an opening, for example an opening in a side wall, in the printer housing. Both the mechanical installation and electrical installation of the smart card cartridge occurs via the opening. This allows the desktop plastic card printer to be quickly and easily retrofitted to have the ability to electronically read data from and/or electronically program data on an integrated circuit chip of a plastic card. The retrofitting can take place without using any mechanical tools and without having to remove the entire, or a substantial portion of, the printer housing.

Embodiments of the specification disclose a transaction execution method, apparatus, and device applicable in a client terminal and a server. The transaction execution method includes: scanning an offline object and a corresponding identification code thereof, the identification code comprising positioning assistance information of the offline object; triggering a recognition process for the offline object and the identification code; and executing a transaction with respect to the offline object based on a result of the recognition process.

A wireless tag communication device for communicating with a wireless tag conveyed in a conveyance direction includes an antenna with a plurality of radiation regions from which a polarized radio wave is emitted and including a first radiation region extending along a first direction crossing the conveyance direction and having a first length in the first direction, and a second radiation region extending parallel to the first radiation region and having a second length that is different from the first length in the first direction, and a controller configured to cause at least one of the first and second radiation regions to emit a polarized wave towards the wireless tag.

A sheet conveyance device has a sheet conveyance path with a first path and a second path. A wireless tag communication device can write information to a wireless tag on a sheet on the first and second paths and receive responses from the wireless tag. A controller controls the wireless tag communication device to attempt to write information to the wireless tag while on the first path, then determines whether information has been written to the wireless tag on the first path according to a response received from the wireless tag. The controller switches a conveyance destination for the sheet to the second path if the information has not been written or to a discharge location if the information has been written. The controller then controls the wireless tag communication device to attempt to write information to the wireless tag while the sheet is on the second path.

According to an embodiment, an image forming apparatus includes a sheet conveyance unit that is configured to transport a print medium along a conveyance path. An antenna is configured to emit radio waves towards a predetermined portion of the conveyance path. A controller is configured to control the antenna to emit the radio waves towards the predetermined portion with a polarization direction set according to a type of the print medium being transported by the sheet conveyance unit. The print medium may have, for example, one or more wireless tags thereon or therein.

A data writing device includes a roller configured to convey a label including a radio tag along a predetermined path, a reader/writer configured to wirelessly communicate with the radio tag, and a controller configured to control the roller to convey the label and control the reader/writer to acquire a plurality of radio wave intensities from the radio tag at different positions along the predetermined path as the label is conveyed, and determine one of the different positions along the predetermined path at which the radio wave intensities are equal to or greater than a threshold value as a writing position for the radio tag.

Systems, methods, and computer-readable media provide automated identification techniques that associate at least two unique identifiers of one segment of a segmental multimode wireless flexible product to seamlessly and accurately bridge different identification methodologies to enable advanced real-time tracking of shipment location and status, and other such useful and advanced product and service offerings.

A tag writing device includes a conveying unit, an antenna, an acquiring unit, a determining unit, a selecting unit, and a deciding unit. The acquiring unit acquires reception intensities about a plurality of wireless tags. The determining unit determines an intermediate position between a start position and an end position as a position where a sum of reception intensities acquired while a mount is conveyed from the start position to the intermediate position and a sum of reception intensities acquired while the mount is conveyed from the intermediate position to the end position are closest. The selecting unit selects, as a target tag, the wireless tag, the intermediate position of which is determined as a position within a prediction range. The deciding unit decides a relative positional relation between the wireless tag and the antenna at a time when writing is performed.
