Abstract
A non-contact identifying device (RFID tag, smart card, IC card, etc.) is configured to enable card possessors to turn on/off a power source by their hands directly or to turn on/off operations of base electronic circuits. When the possessors come and go to a specific region with cards, card data are read involuntarily, which results in infringement on human rights in a conventional non-contact identifying device (hereinafter, referred to as 'card'). However, the non-contact identifying device includes specific circuits in a power supplying circuit or an electronic circuit of the card so that the device is operated only when the card possessors touches a specific portion (switch part) of the card voluntarily, thereby improving security and functions of the non- contact identifying device.
Description
APPARATUS FOR OPERATING CONTROL OF RFID
Technical Field
The present invention generally relates to a non-contact identifying device, and a technology of turning on/off a power source in a non-contact identifying device such as a non-contact smart card or Radio Frequency Identification (RFID) or switching-control an operation of an electronic circuit (hereinafter, referred to as 'communication path') for controlling the flow of data in the device.
Background of the Invention
In a recent ID recognition field, a bar code system and a magnetic card system are applied to physical distribution fields, public phone cards, credit cards so that they have been widely used in our real life. However, the use of smart cards, IC cards and RFIDs with the improved system has been increased by development of technologies and change of the lifestyle. Specifically, the non-contact identifying device is expected to be a main part for Ubiquitous society.
In smart cards or IC cards (size of plastic cards or general credit cards), integrated circuit chips are equipped to have various functions other than microprocessors, operating systems, security circuits and memory devices. As a result, it is possible to process a specific transaction, that is, to process data and communicate with the outside, so that data of those cards are read in a card reader. Depending on the read systems, the cards are divided into contact, non-contact or combined cards.
The RFID is used to distinguish things with both an electromagnetic or electrostatic coupling technology and a data processing technology in a wireless frequency. The RFID as a new technique paradigm which can be replaced with the bar
code system has been widely used in the Ubiquitous system as well as industrial and physical distribution fields. In the RFID, it is possible to transmit information in a long distance by a non-contact method.
A general RFID system comprises a 'read part' including a wireless antenna and a transceiver having a card reader, and a 'card part' including a tag which is a transponder.
The transceiver activates the transponder with a wireless frequency having signal data.
The transponder rectifies and smoothes the wireless frequency, and is activated to transmit stored data into the transceiver through the antenna.
The RFID system for low frequency (30KHz ~ 500KHz) is used in a short transmission region of about 1.8m, and the RFID system for high frequency (85OMHz ~
950MHz or 2.4GHz ~ 2.5GHz) can have a transmission capacity to a long distance of
27m or more. Here, the systems such as IC cards, non-contact smart cards and RFIDs refer to 'non-contact identifying devices'.
Fig. 1 is a block diagram illustrating a conventional non-contact IC card system. The system includes a non-contact IC card reader 10 (hereinafter, referred to as 'card reader') and a non-contact IC card 20 (hereinafter, referred to as 'IC card').
The card reader 10 continuously radiates an electromagnetic wave having a specific frequency. When the IC card 20 is tuned with the frequency of the card reader
10, the IC card 20 is activated with the electromagnetic wave as a power source. After the activated 1C card 20 receives a command from the card reader 10, when the command is normal, the IC card 20 transmits a response to the card reader 10.
If there is no response from the IC card 20 after the card reader 10 transmits the command and a delay time defined in the standard passes by, no more communication is provided. In the non-contact identifying system of Fig. 1 , when it is passive, the system
extracts a power in the RF signal transmitted from the card reader, and provides the power to all circuits of the card. When it is active, an additional power source (battery or charging battery) is mounted to supply a power to the card circuits, thereby exchanging data between the card reader and the card. For operations of the non-contact IC card, ISO/IEC 10536 as a Contactless IC card (CCIC) and ISO/IEC 14443 as a Remote Coupling Communication Card (RCCC) are recommended.
When the IC card system using the non-contact identifying device is used as a residence card or an identification card of employees, behaviors of people and employees are supervised by the system, which results in infringement on human rights.

Preferred Embodiments
The present invention will be described in detail with reference to the accompanying drawings.
Fig. 2 is a block diagram illustrating a passive-type non-contact identifying device (RFID) having a RF signal as a power source from an IC card reader. The identifying device comprises an antenna 210, an analog signal processor 220, a digital signal processor 230, a logic operation unit 240 and a power unit 250.
The antenna 210, which is a module configured to exchange data as a RF signal with an external device (e.g., card reader) for performing communication, transmits an externally received RF signal into the analog signal processor 220 connected to two
terminals Ant+, Ant- of the antenna 210.
The analog signal processor 220 reproduces a reference clock in a carrier wave signal of the RP system received from the antenna 210 to transmit the clock into the digital signal processor 230. Also, the analog signal processor 220 demodulates a high frequency wireless signal to transmit the signal into the digital signal processor 230. The analog signal processor 220 modulates transmission data received from the digital signal processor 230 to transmit the data into the antenna 210 so that the modulated signal is transmitted into the card reader.
The digital signal processor 230 transmits data transmitted from the analog signal processor 220 into the logic operation unit 240, and modulates the data received from the logic operation unit 240 to transmit the data into the analog signal processor 220.
The logic operation unit 240, which includes a microprocessor (CPU) (not shown), a memory (not shown) and a logic element (not shown), performs a general operation control for communicating with the card reader depending on a given protocol. The analog signal processor 220, the digital signal processor 230 and the logic operation unit 240 of Fig. 2 are operation circuits configured to transmit and receive data with the card reader 10 wirelessly and provide a communication path.
The power unit 250 rectifies and smoothes the RF signal received through output terminals Ant+, Ant- of the antenna 210 to render the RF signal a DC power source in the entire device.
Fig. 3 is a block diagram illustrating a non-contact identifying device according to an embodiment of the present invention. The components of Fig. 3 are substantially similar to those of Fig. 2 so that the same reference numbers are used.
The operation controller 260 receives a power source supplied from the supply unit 250 in an Input (I) terminal, and provides an operation power source into the entire
device through an Output (O) terminal. The operation controller 260 includes a mechanical switch module and an electronic switch module. The electronic switch module is turned on only when a given resistance value (O~dozens of KΩ) is connected between terminals A and B so that the power source inputted in the I terminal may be outputted into the O terminal. That is, the operation controller 260 is turned on only when a given resistance value is connected between the terminals A and B so that the power source is outputted into the O terminal. As a result, the operation power source is supplied to the entire device so that the non-contact identifying device may be normally operated. The non-contact identifying device can be used in an active non-contact identifying device (card) as shown in Fig. 4.
A power unit 350 of Fig. 4, which includes a dry cell battery and a charging battery, supplies a power source to the entire device. The operation controller 260 receives the power source outputted from the power unit 350 through the I terminal and supplies the operation power source into he entire device so as to perform a switching control on a power path connected from the power unit 350 to operation circuits 320-350.
Fig. 5 is a block diagram illustrating a mobile communication terminal equipped with an operation controller 460 according to an embodiment of the present invention.
Fig. 7 is a block diagram illustrating a non-contact IC card equipped with an operation controller 560 according to an embodiment of the present invention. Fig. 8 is a block diagram illustrating a non-contact IC card using a charging battery 602 equipped with an operation controller 660 according to an embodiment of the present invention.
The operation controllers 460, 560 and 660 of Figs. 5, 6 and 7 are substantially similar to the operation controllers 260 and 360 of Figs. 2 and 3. Although the operation controller is equipped in the mobile communication
terminal and the non-contact IC card in the embodiment, it can be applied to all devices including a non-contact identifying device such as a PDA, a portable computer, a MP3 player, a credit card, a cash card, a traffic card, an identification card, a residence card, a driver's license, a medical insurance card and a passport. As shown in Fig. 8, the terminals A and B of the operation controllers 260, 360,
460, 560 and 660 are located to be exposed over the surface of the non-contact IC card. When a part of the body of a card possessor contacts with the terminals A and B exposed over the surface of the non-contact IC card as shown in Fig. 9, a given resistance value is formed between the terminals A and B so that a power source may be supplied to the operation circuit.
Although fingers of the card possessor contact with the terminals A and B to operate the operation controller according to the embodiment of the present invention as shown in Fig. 9, it is possible to change a given resistance value or dielectronic constant by physical contacting other than fingers so as to operate the operation controller. Fig. 10 is a circuit diagram illustrating an operation controller of the non-contact identifying device with a Thyristor according to an embodiment of the present invention.
When a given resistance value is formed between the terminals A and B by physical contacting of the non-contact identifying device possessor in the operation controller, the Thyristor (S) is turned on so that the power source inputted from the I terminal is outputted into the O terminal.
Fig. 1 1 is a circuit diagram illustrating an operation controller of the non-contact identifying device with a FET according to an embodiment of the present invention.
When a given resistance value is formed between the terminals A and B by physical contacting of the non-contact identifying device possessor in the operation controller, a first FET (Fl) and a second FET (F2) are turned on so that the power source
inputted from the I terminal is outputted into the O terminal.
Fig. 12 is a circuit diagram illustrating an operation controller of the non-contact identifying device with a transistor according to an embodiment of the present invention.
When a given resistance value is formed between the terminals A and B by physical contacting of the non-contact identifying device possessor in the operation controller, a first transistor (Tl) and a second transistor (T2) are turned on so that the power source inputted from the I terminal is outputted into the O terminal.
Fig. 13 is a circuit diagram illustrating an operation controller of the non-contact identifying device with a toggle switch system using an electronic chip (e.g., IC 4049) according to an embodiment of the present invention. The terminal A is operated as a toggle switch, and the electronic chip senses physical contacting in the terminal A to turn on/off a transistor.
Fig. 14 is a circuit diagram illustrating an operation controller of the non-contact identifying device with a Thyristor combined with a transistor according to an embodiment of the present invention.
Although the operation controller of the non-contact identifying device is an electronic switch whose on/off operations are determined by setting a given resistance value in the embodiment, the electronic switch can be replaced with a mechanical switch whose on/off operations are regulated by physical manipulation of a possessor of the non- contact identifying device.
Moreover, although a path of the power source applied to the base operation circuit is switched to control the operation of the non-contact card in the embodiment, the above-described operation controller is located between both terminals of a communication path formed in the base operation circuit to switch the penetration of the communication path so that the non-contact card is operated only when a possessor of the
non-contact card contacts physically with the non-contact card.
Industrial Applicability
As described above, in a non-contact identifying device (e.g., RFID card) according to an embodiment of the present invention, an electronic switch that can be operated by physical contacting is located in a power source supplying circuit or base electronic circuit of the non-contact identifying device, thereby preventing infringement of human rights which may occur whenever or wherever so as to expand usage limits of a
RFID. The device may be a foundation for Ubiquitous environment like U-City and U- Korea.
