The present invention relates to a method for creating a memo using a mobile phone equipped with an RFID reader, a method for confirming the memo, and a mobile phone in which the function is implemented. More specifically, the method according to the present invention provides a mobile phone user using a mobile phone equipped with an RFID reader. The present invention relates to a method of reading memo tag information attached to a specific object, recording memo contents together with RFID tag information, and checking the memo contents recorded when the specific object is viewed again in the future.

Typically, post notes (3M trademarked trademarks, etc.) are attached to the corners of computer monitors, book bookmarks, etc., to make a simple memo or check the memo. Post-it notes are suitable for sticky notes and detachable notes.

Recently, RFID (Radio Frequency IDentification) technology has been adopted in various fields of the industry. RFID is a field of automatic recognition, such as barcode, magnetic sensor, IC-CARD, etc., and refers to a technology that wirelessly recognizes data stored in a microchip using microwave or long wave. Recently, RFID is increasingly used in the industry to be recognized as a technology to replace the bar code.

An example of the use of RFID technology is to attach an 'RFID tag' containing information about an object to the object, and then read the information by using an RFID reader using radio frequency. In general, while the recognition distance of the barcode is only within 50cm, RFID has an advantage that it can be recognized at a distance of about 27m depending on the frequency band.

2 is a block diagram of a conventional RFID tag attached to an object. 2, the RFID transmitter 200 includes a microchip 202, a transponder 204, and an antenna 206. Transponder 204 is a signal receiver that automatically responds to signals requesting data stored in microchip 202. An antenna 206 attached to the transponder 204 is used to receive a signal for operating the transponder 204 or to transmit data stored in the microchip 202 to an RFID reader. When the transponder 204 is operated, the transponder 204 frequency modulates the data stored in the microchip 202 and transmits the data to the antenna 206. Antenna 206 propagates frequency modulated data to the atmosphere. Also referred to as an RFID tag, including a microchip 202, a transponder 204, and an antenna 206 attached to the transponder.

On the other hand, the memo method of the conventional mobile phone is provided with only a function of recording and storing simple texts in a chronological order.

In the present invention, by applying a memo technique using the above-described RFID technology and post-it (registered trademark of 3M Corporation) to provide a new concept memo method for creating and confirming a memo in a mobile phone equipped with an RFID reader.

In order to achieve the above object, a method for creating a memo using a mobile phone equipped with an RFID reader according to the present invention comprises the steps of: (a) driving a memo writing program by a mobile phone user in a mobile phone having a built-in RFID reader and a memo writing program; ; (b) driving an RFID reader provided in the mobile phone to collect RFID tag information attached to an object to which a note is to be attached; (c) checking the RFID tag to see if it matches the object to which the actual memo is to be attached; And (d) storing the RFID tag information collected by the driving of the RFID reader and the memo content input by the mobile phone user.

Here, the RFID tag information collected by the driving of the RFID reader and the memo input by the mobile phone user are preferably stored in a 1: 1 correspondence.

In addition, the method of confirming a memo using a mobile phone equipped with an RFID reader according to the present invention includes: (a) driving an RFID reader provided in the mobile phone to check whether the memo is stored; (b) driving the memo confirmation program by the mobile phone user in the cellular phone in which the RFID reader and the memo confirmation program are embedded; (c) determining whether a memo content corresponding to the read RFID tag information is recorded in the memo database; And (d) displaying the memo contents recorded if the corresponding memo contents are recorded in the memo database as a result of the determination of step (c).

Hereinafter, with reference to the accompanying drawings will be described in detail a method for creating and confirming a memo using a mobile phone equipped with an RFID reader according to the present invention.

1 is a block diagram of a mobile phone equipped with an RFID reader for executing a memo creation and confirmation function according to an embodiment of the present invention. Referring to FIG. 1, the mobile phone 100 of the present invention includes a central processing unit (CPU) 102, an RFID reader 104, a codec unit 106, a memo writing / checking program 108, The memory 122, the display 110, the keypad 112, the audio 114, the mobile communication modem 116, and the RF unit 118 are configured to be included. The RFID RF signal transmitted from the RFID tag is received through an RFID antenna (not shown) of the RFID reader 104. Here, the coupling scheme used in the RFID tag uses any one of an inductive scheme and a backscattering scheme. In a backscattering scheme called backscattering, the RFID reader 104 sends a signal (energy) to the RFID tag and the RFID tag responds by sending a portion of this energy back to the RFID reader 104. The chip of the RFID tag has a charging device such as a capacitor to enable such an operation. Specifically, each time the RFID tag receives energy from the RFID reader 104, the capacitor is charged and sends a response signal to the RFID reader 104 using the collected energy. In this process, the capacitor is discharged. The signal reflected from the RFID tag modulates and transmits the ID information of the RFID tag to the carrier frequency signal of the RFD reader 104. This process is called backscattering. The RFID reader 104 then demodulates the received information to decrypt the ID information of the RFID tag.

The codec unit 106 codes / decodes voice signals and data. The memo writing / confirmation program 108 wirelessly reads RFID tag information attached to an object and stores the RFID tag information and the memo content in a 1: 1 correspondence. It is a program module that stores code to check whether it is recorded. The memory 122 is a storage unit for storing a program and data required for the mobile phone to operate, and includes a read only memory (ROM) and a random access memory (RAM) that is both read / write memory. . In the memory 122, memos created by the present invention are stored (recorded) in correspondence with the RFID tag information as 1: 1. One example where a memo created by the present invention is stored is shown in FIG. 3. Display 110, keypad 112, and audio 114 are modules that process the user interface, and display 110 typically uses an LCD or organic EL element. The display 110 is for showing various information and signals to the user, the keypad 112 is an input unit by the user, and the audio 114 inputs or outputs an audio signal including a user voice. The mobile communication modem 116 is a signal processing unit for transmitting / receiving a signal between a mobile phone and a base station (not shown), and the RF unit 118 propagates a physically transmitted / received signal to the air.

3 is an example of a database structure stored in a memory of a mobile phone for executing a memo writing and checking function according to an embodiment of the present invention. Referring to FIG. 3, information collected from an RFID tag attached to an object is stored in a 1: 1 correspondence with a memo content input by a mobile phone user. The RFID tag information 'XXXX', 'YYYY' and 'ZZZZ' are unique code information about the object. For example, after reading the MP3 player having 'XXXX' RFID tag information attached to the MP3 player in the COEX mall, the user notes that the price is 100,000 won in the MP3 viewed from the COEX mall.

Hereinafter, a memo writing and checking method according to an embodiment of the present invention will be described in detail with reference to FIGS. 4 and 5. 4 is a flowchart for creating a memo according to an embodiment of the present invention. First, a memo writing program must be driven by a mobile phone user in a mobile phone in which an RFID reader and a memo writing program are embedded (s402). The memo writing program is executed by pressing a specific keypad, which is the user interface of the mobile phone. Certain keypads for note taking and checking must be specifically assigned and marked for note taking and checking at the time of manufacture. Subsequently, the RFID reader is driven by the mobile phone user to collect RFID tag information attached to the object to be attached to the memo (S404). The driving of the RFID reader is preferably made in the same manner as the driving of the camera module of the camera phone, for example. In this case, it is preferable to increase the accuracy of the memo by performing a step (s406) of checking whether the object to be attached to the actual memo and the object to which the RFID tag is attached are matched by the mobile phone user. Subsequently, the RFID tag information collected from the RFID tag attached to the object and the memo content input by the mobile phone user are stored as illustrated in FIG. As the memo input by the mobile phone user is illustrated in FIG. 3, a short price such as 'the price of MP3 as seen in COEX Mall is 100,000 won', 'the price of 20,000 won in the electronic land on February 8' It will be a memo record.

5 is a flowchart for confirming a memo prepared according to an embodiment of the present invention. First, a mobile phone user who has a mobile phone with a built-in RFID reader and memo checking program sees a certain object, and then attaches to the specific object to check whether a memo about the specific object is recorded in the mobile phone he / she holds. In operation S502, an RFID reader is driven to collect RFID tag information. Subsequently, a memo confirmation program for confirming whether a memo is recorded corresponding to the RFID tag information collected for the specific object must be driven (s503). As in the driving of the memo writing program described above, the driving of the memo checking program is executed by pressing a specific keypad which is the user interface of the mobile phone. As mentioned above, the specific keypad for memo writing and confirmation should be specifically assigned and marked for memo writing and confirmation at the time of manufacture of the mobile phone. Next, the information collected from the RFID tag attached to the specific object and the tag information of the object recorded in the memo database are sequentially compared to determine whether the memo content corresponding to the RFID tag information read from the specific object is recorded in the memo database. Determine (s504). If the memo content corresponding to the RFID tag information read from the specific object is recorded in the memo database as a result of the determination in step s504, the memo content recorded in the memo database is displayed (s506).
