Abstract

A burglarproof apparatus using a mobile phone is provided to prevent a mobile phone or other valuable portable equipments from being stolen or missing by attaching an RFID(Radio Frequency IDentification) chip to a smart card or an IC chip and installing an RFID receiver at the main board of the mobile phone so that the mobile phone can be utilized as a receiver and an alarm device. An RFID receiver(2) is mounted at the main board of a mobile phone. The RFID receiver(2) recognizes an RF signal generated from an RFID chip(5). In case it is confirmed that the recognized RF signal is out of a preset value, the RFID receiver(2) transmits an electrical signal to the main board of the mobile phone so that the mobile phone can generate an alarm signal.

Description

Cell phone theft and loss prevention device using cell phone equipped with RFID chip and RFID chip receiver {EQUIPMENT FOR PREVENT OF LOSS CELLULAR-PHONE USE ON BOARD RFID READER CELLULAR-PHONE AND RFID CHIP}

1 is a plan view of the RFID chip receiver mounted with the MAIN-BOARD of the mobile phone of the present invention.

Figure 2 is a plan view of the smart card and the FRID chip attached or directly attached to the IC chip in the card of the present invention.

Figure 3 is a state diagram used between the RFID chip receiver and RFID chip and the MAIN-BOARD of the mobile phone of the present invention.

The present invention relates to an anti-theft device for a mobile phone using an RFID chip (5) attached directly to a smart card (3) or an IC chip and an RFID receiver (2) attached to a mobile phone MAIN-BOARD (1).

In this regard, Korean Utility Model Publication Nos. 98-5806 and 98-4844 disclose loss-proof devices using modulated light. However, modulated light is not uniformly reflected by obstacles or places where many people connect. It is difficult to judge the correct possession of the disadvantages.

In addition, although the Republic of Korea Patent Publication No. 2003-0055708 and Republic of Korea Patent Registration 10-0320192 are registered devices for theft prevention using radio frequencies, they are inconvenient to attach an RF transmitter to each of a number of portable devices and to carry one RF receiver separately. There is a ham.

In addition, smart cards are currently used for transportation cards, pass cards, etc., but the use results are insignificant.

Therefore, the present invention is intended to use a mobile phone as an RF receiver in order to solve the practicality of having to attach the RF receiver to a plurality of portable products, as well as having to carry a separate RF receiver as described above.

In order to mount the RF receiver on the MAIN-BOARD of a mobile phone, the function and size of the RF receiver that recognizes a large amount of RFID chips are greatly reduced, and the electrical signal to simply recognize one to three RFID chips and generate an alarm sound. Adjust to the level that emits.

In addition, the ON / OFF of the remaining loss prevention program, the setting of the alarm sound, and the additional registration of the loss prevention object are controlled by the MAIN-BOARD program of the mobile phone, and the power of the receiver uses the power of the mobile phone.

The first object of the present invention is to use a mobile phone as a receiver for receiving a signal transmitted from an RFID chip, and as a medium capable of comprehensive control by using it as a medium for sounding an alarm sound.

A second object of the present invention is to attach a RFID chip supplied in a specific electric field or a magnetic field to a smart card or a general card without the need for a separate power supply to pursue convenience of use and portability.

In addition, a separate RFID chip can be attached to expensive portable devices such as laptops and camcorders, and can be managed by a mobile phone.

The operation of the MAIN-BOARD of the cellular phone equipped with the RFID chip and the RF receiver of the present invention will be described with reference to FIGS. 1, 2, and 3.

The RFID receiver 2 is mounted on the MAIN-BOARD 1 of the cellular phone, so that the RFID receiver 2 recognizes the RF frequency generated from the RFID chip 5 in the form of a card, and generates an alarm when it is out of the default setting. Send an electrical signal to the mobile phone's MAIN-BOARD to make an alarm sound in the mobile phone.

As described above, the RF receiver is mounted on the MAIN-BOARD of the mobile phone by improving the non-utility and non-portability of the existing belongings and the mobile phone loss prevention device so that a separate receiver is not needed. The separate power supply unit was removed for ease of possession.

Appearance, users do not feel the difference with the existing mobile phone at all, there is no change in design due to the addition of features to reduce the rejection of purchase, and can control all the functions with a mobile phone, so that the cost of expensive mobile phones and other portable equipment or portable products Anti-theft and anti-lost features can increase the value of your phone.

Claims (2)

The RF receiver (2) is mounted on the MAIN-BOARD (1) of the mobile phone, and the mobile phone is used as a receiver, an alarm sound generator, and a comprehensive control medium. The ON / OFF of the anti-lost program, the setting of the alarm sound and the additional registration of the anti-lost object are controlled by the MAIN-BOARD program of the mobile phone. The power of the RF receiver uses the mobile phone's power. RFID chips are used as transmitters to generate frequencies that the RF receiver can receive.
