Description

PORTABLE TELEPHONE WITH NONCONTACT TYPE RF IC CHIP}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mobile phone with a built-in non-contact electronic chip, and more particularly, to a mobile phone with a built-in electronic chip having a unique identifier (ID), wherein the driving power of the electronic chip is supplied from a battery of the mobile phone. The present invention relates to a mobile phone incorporating a contactless electronic chip which can receive payment using a contactless electronic chip at a far distance, by allowing the identification information of the electronic chip to be output to a card reader according to a user's request.

With the establishment of the information age, various types of cards are diversified, and from simple recording media such as magnetic stripe cards, they are now provided with integrated IC (Integrated Circuit) cards incorporating chips.

That is, an electronic chip embedded card (hereinafter, referred to as a 'pass card') that can be used in a subway or a bus is classified into a contact card by a contact terminal, a chip, and an RF contactless card. The contactless card has a loop antenna and an RF IC chip inside thereof, and communicates with a card reader installed in a bus or subway, and is configured to settle a usage fee at a financial server. That is, in this type of pass card, after the user is first provided with the service, the fee information for the provided service and the unique identifier information of the electronic chip embedded in the pass card are immediately or artificially transmitted to the financial server. After a certain period of time (payment date), the payment is made by postpay.

In addition, the bus card using the charging method of the bus card currently in use is a separate charging device by taking a method of re-recording the new value information after calculating the amount of use from the charged amount information while communicating with the card reader, You should go to the charging station where you have installed and settle a certain amount of money and use it after charging new amount information.

According to the conventional contactless wireless recognition card as described above, the user is inconvenient to carry the card separately, there is a risk of loss of the card, there is a problem in that the inconvenience to go to the charging station to charge the amount of money in the card.

In order to solve this problem, the present applicant has applied for patent application No. 99-24789 (filed on Nov. 12, 1999) in which a large number of users always incorporates a non-contact electronic chip in the flip of a mobile phone carrying them. (Name of the invention: a mobile phone with a contactless electronic chip) was presented.

In the conventional mobile phone with a contactless electronic chip, the contactless electronic chip embedded in the pass card can be embedded or attached to a flip or other part of the mobile phone, thereby preventing the loss of the pass card and satisfying the purpose of the card. Therefore, there is an advantage that the amount of use can be conveniently settled using a wireless communication method.

However, according to the conventional wireless recognition card and the mobile phone in which the contactless electronic chip is embedded, the following common problem (s) occur.

That is, since the non-contact electronic chip is not provided with its own power source, the radio wave received from the card reader is used as the energy source. Therefore, since the contactless electronic chip and the loop antenna must be configured at the same time, the size of the product increases, and it is very difficult to construct a loop antenna of sufficient length in a limited size flip. In particular, the length of the loop antenna is also limited in accordance with the specification of the increasingly compact mobile telephone.

In addition, when a non-contact electronic chip is embedded in the mobile phone, the intensity of radio waves is weakened due to the electromagnetic interference device (EMI) included in the mobile phone, which shortens the communication distance between the non-contact electronic chip and the card reader. . Therefore, the user should be close to the card reader as close as possible to the mobile phone with the electronic chip to perform the correct settlement. In particular, when the non-contact electronic chip is incorporated into the portable telephone of the miniaturized trend, the length of the loop antenna is shortened according to the specification of the product, so that the strength of radio waves becomes weaker, and the use efficiency of the card is greatly reduced.

Accordingly, an object of the present invention is to solve such problem (s), and an object of the present invention is to provide an electronic chip embedded in a mobile phone to perform financial settlement, and is required for communication between an electronic chip and a card reader. In order to remove the loop antenna and improve the strength of radio waves communicated, the present invention provides a mobile phone having a non-contact electronic chip embedded therein for driving the electronic chip with a battery power source.
