This specification techniques for sharing service and identity information between devices. One example method include acquiring, by a first device, a digital object identifier (DOI) of a second device, the DOI including identity information associated with the second device; generating, by the first device, a service DOI based on the identity information from the DOI of the second device, the service DOI including the identity information of the second device and service information; and displaying, by the first device, the service DOI on a display of the first device, wherein the displayed service DOI is configured to cause the second device to perform service processing when the displayed service DOI is acquired by the second device, and wherein the service processing is based at least in part on the identity information and the service information included in the service DOI.

A method in a system comprising at least one portable data carrier, an authentication server and at least one reading device of at least one service provider which is couplable to the authentication server. The data carrier is adapted to communicate contactlessly with the reading device and comprises a security marking which can be read contactlessly by the reading device and on the basis of which the data carrier can be authenticated by the authentication server. The method comprises the step of equipping the data carrier with a data-carrier management marking that encodes a piece of data-carrier management information and readable contactlessly by a portable terminal. The method includes contactlessly reading out the data-carrier management marking by a portable terminal, transferring the data-carrier management information encoded in the data-carrier management marking to the authentication server, and managing the data carrier in the system employing the data-carrier management information.

A method of pairing a handheld printer/scanner device with a barcode printer acting as the host is disclosed. The pairing will further enhance the functionality of the host barcode printer. Specifically, the pairing process is initiated when a printer process that requires a handheld printer/scanner device is initiated. The method enables a handheld printer/scanner device to print to a host barcode printer, and also enables the host barcode printer to receive a barcode scan of the case label of received food items and retain information from the barcode scan for future printing of food freshness labels.

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 radio-frequency identification (RFID) printer-encoder is provided. The RFID printer-encoder includes a feed path configured to accommodate a plurality of RFID tags. The RFID printer-encoder further includes a print head positioned along the feed path. Furthermore, the RFID printer-encoder includes a multi-mode active antenna configurable in a plurality of antenna modes. Each of the plurality of antenna modes has a distinct radiation pattern.

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.

According to an embodiment, a control device for an image forming apparatus includes a controller that acquires reference information corresponding to expected signal strength values from a wireless tag on a sheet moving along a conveyance path and also acquires measured signal strength values for a first wireless tag on a sheet from a wireless tag communication device. The controller calculates a similarity value from the measured signal strength values and the expected signal strength values to determine whether the first wireless tag is on a sheet moving along the conveyance path. The controller controls the wireless tag communication device to write information to the first wireless tag when the calculated similarity value is above a threshold similarity value.

A printer assembly is described that includes a media hub configured to receive a media roll and supply a media from the media roll along a media path, wherein the media includes a plurality of labels each comprising a Radio Frequency Identification (RFID) inlay. The printer assembly also includes a media guide positioned adjacent to the media path. The media guide includes an RFID antenna, with the RFID antenna communicatively coupled to an RFID control system and configured to transmit signals to encode the RFID inlay on a first label. The media guide also includes at least one shield, wherein the at least one shield is positioned adjacent to the RFID antenna to prevent, during an encoding of the RFID inlay on the first label of the plurality of labels, an encoding of the RFID inlay on a second label of the plurality of labels.
