A connecting method, apparatus of a screen transmission device based on NFC, and a computer device are provided. The connecting method of the screen transmission device based on NFC includes touching an NFC tag, and identifying whether the NFC tag contains network information of the screen transmission device; and when the NFC tag contains the network information of the screen transmission device, acquiring the network information, and connecting with the screen transmission device according to the network information.

A system for prevention of electrostatic discharge from a payment card to a point of sale (POS) device comprising an integrated circuit card (ICC) socket, includes a spring member comprising a first end electrically coupled to a second end. The first end is electrically coupled to an electrical ground, the first end is mechanically coupled to the POS device, and the second end is positioned for contact with a top edge of the payment card. When the payment card is inserted into the ICC socket and the top edge comes into contact with the second end, the first end and the second end form a first electrical path for electrostatic discharge between the payment card and the electrical ground.

According to one embodiment, a reading apparatus includes a shielding body, an antenna, and a reader and writer. The shielding body is formed in a box shape with an upper opening, to place an accommodating body and to shield radio waves. The antenna is provided in the shielding body to receive information from an RFID tag attached to a product that is passing through the opening. The reader and writer is connected to the antenna to read information of the product from the information received by the antenna.

A process for triggering projected displays can comprise determining that an RFID device has moved within a predetermined range of a first interrogator, wherein the RFID device is carried by a user. The RFID device can be interrogated to determine a first identifier. Based on the first identifier, an identity of the user can be determined. A projection command can be transmitted to a projection source, wherein the projection command comprises the identity of the user and instructive indicia comprising information about a toy, wherein the toy comprises a second RFID device.

Material in a supply chain is tracked by a method of applying a DNA taggant set to a first batch of the material produced by a first supplier of the material. The DNA taggant set corresponds to a tag string corresponding to the first supplier. The first batch is aggregated with a second batch to create an aggregated lot. A sample is selected from the aggregated lot and tested to determine a DNA taggant set of the sample. After selecting a sample from the aggregated lot, the sample may be labeled with a grade and then placed in a receptacle corresponding to the grade.

A card processing device is structured to process a card having a plurality of information recording parts from which information is capable of being optically read. The card processing device includes a placing part which is formed with a placing face on which the card is placed, a reading part which is provided on an upper side with respect to the placing face and is capable of optically reading information from at least one information recording part of the plurality of information recording parts, and an attaching part for detachably attaching a cover member which covers the at least one information recording part of the plurality of information recording parts provided on the card which is placed on the placing face.

A multi-loop antenna and an RFID system are used for monitoring tools when machining rotationally symmetric workpieces. A multi-loop antenna is arranged on a tool carrier near a rotationally symmetric tool so that multi-loop antenna encloses the rotationally symmetric tool and the rotationally symmetric tool carries an RFID transponder. The position of this RFID transponder is arranged on the rotationally symmetric tool so that it is arranged in the electromagnetic ring field of the multi-loop antenna. The multi-loop antenna is arranged on the tool carrier so that it is possible to query the RFID transponder on the rotationally symmetric tool in any position while in motion and when at rest.
