Wherein the synchronization request comprises a request type; the electronic business card file is obtained by dividing the contact information stored by the first terminal into at least two parts, respectively packaging and numbering. Specifically, after the first terminal packages the contact information, all electronic business card files are numbered. Preferably, the first terminal equally divides the contact information stored therein into at least two parts and packages the two parts into the electronic business card file, in other embodiments, the contact information stored in the first terminal may be divided into at least two parts with unequal numbers and packages the two parts into the electronic business card file. However, whether equally divided or unequally divided, each electronic business card file contains the number of contacts contained in the electronic business card file. The number of the electronic business card file can be continuous or discontinuous Arabic numerals such as 1, 2, 3 and 4, and can also be English letters or other types of letters as long as the rules are provided, and the method is not limited herein.

Specifically, the second terminal sends a bluetooth connection request to the first terminal, and establishes a bluetooth connection with the first terminal after the first terminal receives the connection request of the second terminal. After the connection is completed, the second terminal judges the current state of the second terminal so as to determine the type of the synchronization request sent to the first terminal.

And if the second terminal determines that the current state of the second terminal is the login state, namely any electronic business card file is not stored in the first cache unit, the second terminal sends a login request to the first terminal so as to obtain a first electronic business card file from the first terminal.
