Wireless method for obtaining external data, electronic device and application program

A wireless method for obtaining external data is comprised of an electronic apparatus, an external message and an external device. The electronic apparatus reads the external message without physical contact, and identifies a Media Access Control (MAC) Address of the external device in accordance with the contactless message. The electronic apparatus establishes a wireless connection with the external device directly using the identified MAC Address, and obtains needed data from the external device through the wireless connection. Therefore, this wireless method circumvents the hassle for user to turn on and off a Bluetooth transmitting unit of the electronic apparatus, select a connecting target, and establish the wireless connection with the external device manually all together.
