3 is an operation flowchart of a business card information transmission and reception program between wireless electronic business cards.

The step of transmitting and receiving business card information between the wireless business card device is to initialize the wireless business card control program and prepare for transmission and reception (step S1), wait for command button input and information exchange (step S2), and check whether the transmission and reception mode (step S2). S3) In the transmission / reception mode, business card information is transmitted and received (step S4).

If it is not the transmission mode, it is checked whether it is a transmission mode (step S5). If it is a transmission mode, card information is transmitted (step S6). If it is not a transmission mode, it is checked if it is a reception mode (step S7). (Step S8).

If it is not in the reception mode, it is checked whether the power is off (step S9), and if not, the next operation is executed (step S10).

4 is a flowchart illustrating an operation of transmitting and receiving a program between a wireless electronic business card and a computer.

In the transmitting and receiving step between the wireless business card device and the computer, the wireless business card control program is initialized and prepared for transmission and reception (S11), waiting for a command button input and a transmission / reception mode (step S12), and checking whether it is in a transmission mode (step S13). In the transmission mode, the transmission business card is selected and transmitted to the computer (step S14).

If not in the transmission mode, it is checked whether it is in the reception mode (step S15). If it is in the reception mode, the selected card information is received from the computer and stored (step S16).

If it is not in the reception mode, it is checked whether it is a valid operation command of the wireless business card device (step S17). (Step S18).

When an individual introduces his / her business card information to a large number of individuals, the send / receive mode of operation puts the wireless electronic business card of the introducer in the transmission mode, and the majority of the listeners receive the introduction in the receiving mode. If you press and hold the human action button for about 2-3 seconds, the wireless electronic cards in the receive mode receive the card information and store it in the internal flash memory. Referring to FIG. 3, when exchanging one's own business cards with each other, the card is operated in a transmission / reception mode and simultaneously transmits and receives business card information.

If you enter your business card information at the place where you purchase a wireless business card, if you have a digital photo image or if you can make a photo image with a digital camera, you can easily enter or change your business card information with the provided simple business card program. In this case, the reception from the computer is required, and the same interface method as the transmission to the next computer can be used.

When you want to store the accumulated business card information in your computer, you can send it to your computer in two ways.It is connected to the serial port of the computer by using a connector such as DB9 and transmitted using the RS232C interface and a cable. There are two ways to send business card information wirelessly to computer by using the function.

In both cases, a computer can execute a reception program to receive business card information from a wireless business card and store it in a business card database. The data structure at the time of transmission and reception consists of digital image data and text information data, and the resolution, color or black and white of image can be selected according to the implementation method and transmission speed, and it is implemented considering the use of compression method and wireless transmission speed. Just do it. At this time, the data structure and size are determined according to the implementation method.

For example, if you use a 9600bps transmission speed of 2K bytes of photo image 32K64X (8bits) and 1Kbytes of character information, a total of about 3K bytes can be transferred within about 2 to 3 seconds.

Therefore, by using a wireless business card device instead of a paper business card, wireless business cards can be exchanged with each other wirelessly, a large amount of personal information can be stored, and electronic business cards can be exchanged simultaneously with many people in the room.

As described above, the wireless electronic business card apparatus and control method according to the present invention can wirelessly send and receive electronic business cards to a large number of individuals or indoors wirelessly at the same time, and can systematically manage business card information, and between business cards In exchange for business cards instead of paper business cards, you can store a large amount of personal information by mutual exchange, can be exchanged with a large number of people at the same time, wireless card function can be included in the electronic notebook if necessary, or business cards It can be used only with a wireless business card having a function, and it is effective to transmit and receive the stored information to a computer through a computer interface.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the invention as set forth in the claims below. It will be appreciated.
