Description

Cell phone battery with non-contact electronic chip {Cellular Phone Battery Having Non-Contact Type RF IC Chip}

(Technology)

The present invention relates to a mobile phone battery, and more particularly, a battery that is mounted to supply power to a mobile phone, and has a built-in non-contact RF electronic chip for payment. The present invention relates to a mobile phone battery equipped with a contactless electronic chip for payment.

(Background)

As informatization progresses, payment methods for various goods and services are also rapidly moving from traditional cash to credit cards and electronic money, and transportation cards are gradually replaced in cash for transportation charges such as subways and buses. It is widely used and recommended.

As a transportation card, one of the most common electronic money, a prepaid contactless RF card with a credit card size having a contactless RF electronic chip and a loop antenna has been mainly used.

This prepaid contactless transportation card saves (charges) the desired amount by paying in advance the charge to be charged at the charging station, and accesses the card contactlessly to the reader every time the transportation is used to save the amount of money. This is a transportation card that reduces the applicable fare.

When using such prepaid transportation card, it is inconvenient to visit the charging station and charge it. To solve this inconvenience, a postpaid transportation card with a credit card concept has been developed, and the prepaid transportation card is a card user stored in the card. It is a transportation card (such as a credit card combined with a transportation card) that allows a user to pay a transportation fee by credit (postpaid) by identifying a user through a process of reading an ID.

Recently, cards have been developed that can be used in combination with contact and contactless recognition, prepaid and postpaid.

With the widespread dissemination of traffic cards with various usages and methods as described above, a user can conveniently pay for a transportation fee while carrying a traffic card in a wallet or the like. However, all existing transportation cards have to be carried with them separately at all times by separately purchasing (prepaid) or applying (postpaid).

On the other hand, the present inventors have incorporated the design of Utility Model Registration No. 180261 by incorporating an RF electronic chip and a loop antenna embedded in a traffic card into a mobile phone, so that the mobile phone can be used in place of a traffic card without a separate traffic card. It was suggested as such.

A mobile communication terminal represented by a mobile phone is widely used as one of daily necessities due to the convenience of freely moving and communicating without being restricted by a subscriber's location.

However, in recent years, the harmfulness of electromagnetic waves has been known through various papers and experiments. Especially, in order to improve call quality, high frequency electromagnetic waves (GHz), which are higher than other electric devices, have strong radio wave strengths. In addition, much attention has been focused on the harmfulness of electromagnetic waves than any other electronic products in relation to the mobile phone that is in close contact with the head.

According to US and European standards, which have begun to regulate electromagnetic waves ahead of the Republic of Korea, the Specific Absorption Rate (SAR), which refers to the unit mass and the energy accumulated in human tissue per unit time, has a specific Absorption Rate (SAR) per gram or 10 grams of tissue. It is recommended that 1.6W / KG or 2.0 W / KG or less, and the Ministry of Health and Welfare recommends not to talk continuously for a long time (more than 10 minutes once) and to pull out the antenna as much as possible.

In line with the atmosphere related to electromagnetic hazards, mobile phone manufacturers have introduced mobile phones to which various electromagnetic wave blocking functions such as an electromagnetic wave shielding filter or an electromagnetic wave shielding case are applied.

Under such a technical background, in the mobile phone to which the electromagnetic wave blocking function is applied, a mobile phone with an RF electronic chip and a loop antenna developed by the present inventors mentioned above may cause some problems in its operation. In other words, as the electromagnetic wave blocking function is applied to a mobile phone, communication for forming induced electromotive force between the loop antenna and the reader embedded in the mobile phone is disturbed, which shortens the communication distance, thereby eventually bringing the mobile phone closer to the reader. If you do not do this, the communication will be incomplete.

In order to solve such a problem, the inventors of the Utility Model Registration Application No. 20-2001-0024814 filed on August 18, 2001, the RF electronic chip is embedded in the mobile phone and the loop antenna to supply power to the mobile phone. In addition to the built-in battery for the purpose of the present invention has been proposed that the electrical connection between the RF electronic chip and the loop antenna is made through the connection terminal provided in the mobile phone and the battery.

An object of the present invention is to solve the problem of shortening the communication distance caused by the electromagnetic interference blocking action of the mobile phone and the reader in a mobile phone having a fare payment function (e.g., a transportation card function). In order to ensure that the mobile phone can be used as a payment method regardless of the electromagnetic wave blocking action of the mobile phone, by installing the RF electronic chip and the loop antenna for the mobile payment, which are essential for the mobile phone, but which have almost no electromagnetic wave blocking action. It is.
