[0001] INTERLOCKING MULTI CARD READER USING MOBILE [0002]

The present invention relates to a card reading device, and more particularly, to a card reading device for transmitting card information to a mobile terminal such as a smart phone.

In the modern society, credit cards are widely used as a means of replacing cash settlement, and tend to induce credit card settlement in all fields of society such as on-line and off-line stores, restaurants, hospitals and pharmacies.

Most of the credit card payments are made through offline merchants, but mobile payment services using mobile payment terminals have been performed in recent years.

However, in the past, mobile payment services have not been activated due to the initial cost burden and insufficient payment terminals. However, in recent years, the availability of available terminals has expanded and various services have been launched successfully. As a result, mobile payment has become a new core payment method due to the active infrastructure construction under the government initiative.

In addition, due to the introduction of NFC cards or RF cards using near field communication (NFC) technology or radio frequency (RF) technology, a new type of credit card that replaces the existing magnetic card has become popular, The foundation for enlargement is being established. For example, Korean Unexamined Patent Publication No. 2011-0084865, entitled " Method and apparatus for mobile ID card contact / non-contact communication using Mobile ID ", proposes a mobile payment system using local communication.

However, since the mobile payment terminal, which is an essential element for mobile payment service, is still being distributed only as a dedicated terminal, it must be purchased separately and the actual price is relatively high, which is an economic burden for the merchant who has to purchase the mobile payment terminal. In addition, even if a mobile payment terminal is distributed as a dedicated terminal, there is a portion that is relatively inconvenient due to its size.

Accordingly, it is an object of the present invention to provide a method and apparatus for transmitting card information to a mobile terminal such as a smart phone through a standard audio plug and a communication port of the terminal, It is an object of the present invention to provide a card reading device that increases the convenience of the user by using both the magnetic card, RF, and IC card reading.

According to an aspect of the present invention, there is provided a card reading device module including a connection terminal connected to a mobile terminal storing a payment program, A main reader having a magnetic reading unit for transmitting the card information for payment to the mobile terminal; And a sub-reader for recognizing the card information through an RF signal or IC information of the card and transmitting the card information to the main reader.

Wherein the sub reader comprises an RF reader having an RF reading unit for recognizing the RF signal and an IC reader for recognizing the IC information, wherein the RF reader and the IC reader are electrically connected to each other And any one of the RF reader and the IC reader connected to each other may be connected to the main reader to select one or more of the magnetic, RF signal, and IC information to recognize the card information.

The connection terminal of the main reader includes a standard audio plug coupled to the standard audio jack of the mobile terminal for transmitting / receiving signals and a main communication terminal coupled to the mobile communication port of the mobile terminal for transmitting / receiving information .

The standard audio plug may be rotatable about one end connected to the main reader so as to be selectively positioned inside the main reader.

The main reader may further include a voice output unit for outputting any one of whether the card is settled or the card information is recognized.

According to the present invention as described above, the following effects can be obtained.

The card information for payment can be recognized by magnetic lines, RF, IC, etc. According to the present invention, card information such as magnetic lines, RF, IC, Accordingly, the convenience of the payment system using the mobile terminal is increased.

In addition, since the payment information can be transmitted to the mobile terminal by selectively coupling the main reader to the mobile communication port or the audio jack of the mobile terminal, the user can select the part to be combined and proceed with the payment if necessary. The convenience of the user is increased.

In addition, since the barcode reader of the sub-reader provides the product information to the mobile terminal, the user can easily manage the inventory and pay for the product, thereby enhancing convenience for the user.
