## Background
FIELD OF THE INVENTION
This invention relates to a technical field of information processing and that of information exchanging, and especially to a method for delivering an electronic business card by combining geographical location information and Bluetooth technology as well as a delivering system for realizing such delivering method.
DESCRIPTION OF THE RELATED ART
Business card is a medium that people usually use to carry and deliver contact information. A lot of business cards are exchanged in daily business activities, and people communicate contact information by exchanging business cards, so as to establish communication with others.
Nowadays, business cards exchanged by most people are printed papery business cards. The problem brought by the conventional way of exchanging papery business cards is that when a papery business card is received from someone else, business card information (mainly including contact information such as name, profession, job title, company name, telephone number and E-mail, additionally, may also include some company information such as company name, company address and business field of the company) usually need to be electronized by manual input, so that the business card information can be stored into the address book of computers or mobile terminals. Additionally, when contact information need to be provided during remote communication (for example, telephone) or face-to-face communication (non-papery business card), in order to record the information data of a contact (such as telephone number, cellphone number, e-mail, address, company name, and so on), a notebook is often needed to record those information data, or those information data need to be manually inputted into the address book of computers or mobile terminals. Thus, operations for inputting information data are inconvenient; the accuracy of inputted information data is not guaranteed; and the information data is often incomplete and has errors.
Some existing mobile terminals provided with camera (cellphone, PDA, tablet computer or laptop and the like) have the function of scanning business cards, by directly taking a picture of the business card only by using the micro distance photography pattern of the camera, uses the principles of image processing and optical character recognition (OCR, Optical Character Recognition) to automatically process and recognize the business card image being taken, and then automatically extracts some information such as name, telephone number, E-mail and so on therefrom so as to add such information into the address book, thus bringing great convenience for those people who want to input the contact information recorded in the business card into the electronic device. However, even so, characters recognized by OCR can't be 100% accurate, which means that the user has to check and correct them manually. Thus, it is troublesome, and it is no better than direct delivery and exchange of electronic business cards. Additionally, in the above application situations, the problem of how to input the data after the printed papery business cards are exchanged can only be partially solved, while the problem of how to input the data in case of remote communication or when there is no business card are still unsolved.
On the other hand, the electronic business card is emerging, and some mobile terminals are provided with functions of editing and exchanging business cards. If the function of exchanging electronic business cards is to be realized, unilateral delivery or mutual exchange can be performed by means of a communication network. The electronic business card can be transmitted via SMS (short messaging system), data transmission, e-mail, and so on.
Existing mobile terminal in the market normally support GPS positioning and Bluetooth technology. The accuracy of GPS positioning has a certain error range. The error range of a commercial GPS positioning system is usually within 20 m when it can directly connect to a GPS satellite outdoors, however the accuracy of the GPS positioning would significantly reduce indoors, where the error may be several hundred meters. Meanwhile, the communication distance of the Bluetooth technology is about 8 m to 30 m, if two or more users located within the detection range of their own Bluetooth communication devices want to deliver data through the Bluetooth technology, those users need to firstly agree on a password, establish connection by inputting the same password, and then transmit data by using Bluetooth connection; such operations are inconvenient.
