Description

Apparatus for reading in radio frequency identification

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio frequency identification (RF-ID) reader, and more particularly, to a radio reader for facilitating an interface with a personal portable terminal (eg PDA).

In general, the RF-ID reader is a device for reading an RF-ID card (tag), which is a contactless card, which changes production methods, changes in consumer consciousness, advances in culture and technology, barcodes and magnetic cards. Disadvantages The RF-ID card, which has been improved by the need for resolution, is activating.

RF-ID is widely used as a means for classifying goods and products and automatically processing data in office automation or factory automation.

The information system using the same is shown in FIG.

1 is a block diagram showing the configuration of a conventional wireless recognition reader.

Here, reference numeral 10 denotes a tag in which an ID and data are stored, reference numeral 20 denotes a radio reader which reads the information stored in the tag 10, and reference numeral 30 denotes a radio reader 20 Represents a host system connected by wire to process the read information.

The tag 10 is attached to a product or a product for automatically processing the information, and the information held by the tag 10 is read by the radio reader 20.

Various techniques are used to configure the tag 10 and the wireless reader 20, and each technique has its own advantages, but any system must have a reader for the construction of an information system using RF-ID. in need.

The information read by the radio reader 20 is transmitted to the host system 30 to be processed according to the purpose.

Looking at the process of information transfer, the tag 10 to the radio reader 20 is processed wirelessly, from the radio reader 20 to the host system 30 is processed by wire.

The distance from the tag to the reader that can accurately read the information depends on the technology that makes up the tag and the reader, but the shorter is tens of millimeters (MM) to several meters (M) long.

Therefore, the use is limited because of the distance constraints.

Also, the reader simply passes the tag's information to the host system, so the next process based on the read information is at the host. Since the host is not easy to move, there is a limit in configuring an information system characterized by movement.

On the other hand, an information system using a personal digital assistant (PDA), which has been rapidly spreading in recent years, is configured as shown in FIG.

As shown, the personal portable terminal 40 (PDA), a receiver 50 for receiving a signal transmitted from the personal portable terminal 40, and the receiver 50 are connected to process the received information. The information processing system 60 is comprised.

An information processing system using a personal portable terminal also basically features a wireless mobile information system owned by a personal portable terminal.

The information held by the personal portable terminal 40 can be transmitted to the information processing system 60 via the receiver 50 as necessary.

In this case, the information processing system 60 serves as a server that manages a host or a plurality of PDAs.

In the case of a personal portable terminal, it can act as a host by itself. In the case of a personal portable terminal, the distance for transmitting information by wireless is usually several tens of meters.

Therefore, the present invention is proposed to improve the disadvantages of the conventional radio reader as described above,
