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.

In 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. 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 a unique identification code (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).

Based on the data provided by the credit card company, it is determined whether the corresponding RF electronic chip 31 is usable. Then, if it is available, data about the fee to be settled by forming a unique identification code (ID) and payment is made. Will be treated as credit.

At this time, the reader 41 provided in the subway is connected to the subway management server 43 provided in the subway headquarters, etc., thereby transmitting the corresponding data to the financial server 42 through the subway management server 43 through a communication network and paying the transportation fee. The reader 41 disposed on the bus generally has to settle with a unique identification code (ID) because communication with the bus management server 44 or the financial server 42 of the bus company is not connected. The data related to the fee is stored in the recording medium 41a of the reader 41 and then transferred to the financial server 42 via the bus management server 44 in a batch to process the transportation fee payment as credit. .

However, in the conventional portable terminal structured as described above, the portable terminal is brought closer to the reader 41 so that the other side of the battery 11 having the loop antenna 32 is formed toward the reader 41 at the time of transportation card or electronic payment. It can be used only when it is in close proximity, and if the opposite direction is placed so that the folder 20 side faces the reader 41, it will not work. Therefore, it is inconvenient to use the other side of the battery to face the reader 41 during use. There is a ham.
