Method for pairing between bluetooth devices using tag and bluetooth device for the same

A method for pairing Bluetooth devices using tags and the Bluetooth device thereof for the same are provided to omit a query process for obtaining Bluetooth device information from the Bluetooth devices, enable a user to use the Bluetooth devices in a safe and simple procedure without making the user input a PIN(Personal ID Number) code, and prevent an unauthorized user from using the Bluetooth devices. A master Bluetooth device(100) includes a tag reader(110) and a Bluetooth connection controller(120). The tag reader recognizes that a tag ID includes slave Bluetooth device information based on header information included in the tag ID by receiving the tag ID from a contactless tag(300), and extracts the slave Bluetooth device information from the tag ID. The Bluetooth connection controller operates the tag reader when pairing between the master Bluetooth device and a slave Bluetooth device(200) is requested, and pairs the master Bluetooth device and the slave Bluetooth device through the slave Bluetooth device information when the extracted slave Bluetooth device information is received from the tag reader.
