Method for establishing connection between wireless communication devices

A method for establishing a connection between wireless communication devices, suitable for sharing data between a sender and a receiver, wherein both the sender and the receiver have a built-in acceleration sensor and the connection method comprises:

• establishing a first-connection between the sender and at least one receiver;
• bumping the sender against the receiver;
• receiving an external tap-data from the at least one receiver by the sender via the first-connection, wherein the sender obtains an internal tap-data through the built-in acceleration sensor thereof and the receiver obtains the external tap-data through the built-in acceleration sensor thereof;
• comparing the internal tap-data with the external tap-data to filter out non-receivers but confirm the receiver;
• and
• establishing a second-connection between the sender and the receiver according to a security protocol so as to mutually share data between the sender and the receiver via the second-connection.
