It is composed of an EPC Information Server (IS) 140 to be connected. The EPC IS 140 provides a service for exchanging data related to the EPC with the counterpart through the EPC global network, and the RFID middleware 130 manages real-time lead events and information for communication with the EPC IS 140. It provides an alarm, and manages basic lead information for communication with the EPC reader 120.

The reader 120 is called a transceiver and is a device that sends data to or reads data from the tag 110 through an RF interface. The reader 120 should be able to recognize a unique identification code from the tag to avoid collision with other features without physical contact with the tag 110.

 Tag 110, also known as a transponder, consists of a processor for protocol execution and cryptography, a memory for storing data, and an RF antenna. The tag 110 is divided into an active tag having a built-in battery and a passive tag that receives RF signals from a reader and generates power for operation. And the RF frequency between the tag 110 and the reader 120 uses 125KHz, 134KHz, 13.56MHz, 433.92MHz, 860 ~ 930MHz, 2.45GHz band. The EPC Global Class 1 GEN2 specification is a protocol standard in the 860-930 MHz band (UHF).

However, an RFID card issuing device capable of collectively updating or individually updating the tag ID of the EPC Global Class 1/2 tag has not been developed yet.

Accordingly, the present invention has been proposed to meet the above necessity, and an object of the present invention is to provide an RFID ID card issuing apparatus capable of collectively updating or individually updating the tag ID of an EPC Global Class 1/2 tag.

In order to achieve the above object, the card issuing device of the present invention comprises: an RFID card issuing device for issuing an RFID card by reading / writing an RFID card, the key input unit being operated by a user; A memory in which various software and data are stored; Display means for displaying an operation state, data read from the RFID card, data to be written to the RFID card, etc. under the control of a microprocessor; Communication unit; A tag read / write module configured to communicate with the RFID card to read data recorded on the RFID card and transmit the data to the microprocessor, and to write the EPC code to the RFID card under the control of the microprocessor; A tag slider for continuously inputting a large number of tags or inputting and discharging individual tags under the control of a microprocessor; And controlling the tag read / write module to read / write the RFID card according to an EPC Global Class1 GEN2 protocol, to communicate with an external host through the communication unit, and to input the key. It characterized in that it comprises a control unit for controlling the entire operation according to the user's operation input through the unit and display on the display means.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, a brief description of the EPC for the understanding of the present invention, the Electronic Product Code (EPC) is a concept that includes a network standard for utilizing RFID technology based on the Internet as the identification code of the RFID. The RFID tag stores only minimal information such as EPC code, which is a product identification code, and retrieves detailed information related to the product through the Internet.

EPC standards include an EPC code system, an object naming service (ONS) that indicates the location of the computer where the details are stored, an EPC Information System (EPC IS) that stores the details, and RFID tag readout information to be filtered or sent to the required location. Note consists of middleware and the like.

In principle, RFID tags can store a large amount of information as needed, but in practice, it is more efficient to store only minimal information to reduce tag-related costs. The EPC code is a product identification code developed for this purpose, and is different from the existing barcode number in that a serial number for identifying all individuals individually even for the same product is added.

There are various types of EPC codes, but the most widely known 96-bit code (GID, General IDentifier-96) is stored in a memory in the form as shown in FIG. Referring to FIG. 5, a CRC, an EPC code, and a PASSEORD are stored in a memory of a tag. A 96-bit EPC code is represented by 96 binary numbers, an 8-bit version (header), and a 28-bit domain manager (company) Code), 24-bit object class (commodity code), and 36-bit serial number (serial number).

In the present invention, the EPC code is modified to suit the purpose of use and used as a code for identifying employees or visitors.
