Abstract

PURPOSE: A PDA capable of transferring electronic fund for electronic money is provided to make a PDA perform a function as an auxiliary device for an electronic fund transfer of an electronic card for an electronic money through a semiconductor chip built in the PDA, other recording device, or software. CONSTITUTION: Two wireless information transmitting interface devices or two insertion interface devices capable of reading and writing an electronic money card attached on a PDA electrically are provided. Computer systems(12) of an electronic money managing company are connected to the interface devices through a telephone communication network. he PDA for a fund transfer function of electronic money has a pair of interface devices or two pairs of interface devices. The wireless information transmitting interface devices are manufactured as a contact type for contacting a card on the PDA for performing a function or a non-contact type for making a function be performed at a predetermined distance from the PDA. A control module(5), an input/output module(6), and a calculation module(7) are included in a system structure(11) for an electronic money function being performed through a semiconductor chip built in the PDA, other recording device, or software. The system structure(11) controls the interface devices. The computer systems(12) comprises a control module(9) and an electronic money managing module(10). A database function may be included in the computer systems(12). Two interface devices are necessary for reading and recording information in two electronic money cards, respectively, in a fund transferring process.

Description

Method and system for operating a function of PDA and electronic money with electronic money transfer function for electronic money. {The PDA that has the function of electronic money transfer of the electronic cash, and the operation system and the method of it.}

The technology in the field to which the present invention belongs may be regarded as a field related to the field of auxiliary electronic devices for electronic money or a personal digital assistant (PDA). Conventionally, an electronic money terminal device performs a function similar to a credit card terminal device.

On the other hand, in the past, PDAs generally had functions similar to those of personal computers, or had mobile telephone network functions.

'PDA (Personal Digital Assistant)' in the present invention basically has a CPU, a memory, an OS, various application software, and various input / output devices, such as a personal computer, and is made of several hundred grams or less so that an individual can easily carry it. It refers to a portable terminal device. PDA can be defined with the same concept as HPC (Handheld PC).

In addition, the term 'electronic money' in the present invention is to enable the electronic chip to record and change the value of money (funds) in a semiconductor chip or other electronic recording device or software, so that money (funds) are stored and transferred electronically. It means that can be performed. Such electronic money is now generally implemented in the form of plastic cards.

The present invention is intended to perform the function of the PDA as an auxiliary terminal device for the electronic funds transfer of the electronic money electronic card through a semiconductor chip (chip) or other recording device or software embedded in the PDA itself. In other words, when you want to transfer money electronically from one electronic money electronic card to another electronic money electronic card, it is to use PDA as an auxiliary device to perform this function.

In addition, by using the input device of the PDA, it is necessary to have a function to perform an electronic command for setting a transfer amount and performing other money transfer functions when transferring money. Furthermore, the mobile phone communication function of the PDA should be justified by the electronic money management company's computer system when the electronic money is transferred to the electronic money, and be able to exchange information between the electronic money card, PDA and electronic company computer system.

The present invention basically provides two wireless information transfer interface devices (1, 2) or two insertable interface devices (3, 4) which enable electronic reading and writing of a PDA and an electronic money card attached thereto. And computer systems 12 of an electronic money management company connected to a mobile telephone communication network. In this case, the PDA may have only one pair of interface devices such as one, two, three, or four as shown in FIG. 1 or both pairs. There may be two types of wireless information transfer interface devices such as 1 and 2, which are functions of contactlessness, in which a function is performed even when the card is contacted with the PDA for a short time and a certain distance is maintained.

The structure 11 of the system for the electronic money function performed through a semiconductor chip or other recording device or software embedded in the PDA itself includes a control module 5, an input / output module 6, and a calculation module 7. It is included, which also controls 1 to 4 interface devices 8. The computer system 12 of an electronic money management company basically consists of a control module 9 and an electronic money management module 10, which may also include a database function. There are two interface devices 1 to 4, respectively, because the information must be read from two electronic money cards and recorded thereon at the time of money transfer. Each of these two interface devices may be provided with one, two, three, or four pairs of interface devices in one PDA, depending on the method. Electronic card insertion interface devices such as 3, 4 can be attached to the outside of the lid if necessary.

If the method and system made through the present invention are utilized, the money transfer function between electronic cards for electronic money will be convenient and the utility value of the PDA will be increased. In addition, it may also have an economic effect compared to having a mobile terminal device for the transfer of funds.
