  • Publication number: 20150365133
    Abstract: An NFC reader in a communication device reads a first NFC tag on a first conference device when the communication device is brought within proximity of the first NFC tag. The communication device communicates information read from the first NFC tag and information acquired by the communication device to a conference server. The conference server utilizes the communicated information read from the first NFC tag and the communicated information acquired by the communication device to configure a conference call between the first conference device and the second conference device. The communication device, the first conference device and the second conference device are separate and distinct. The communication device executes a module that handles the communication of the information read from the first NFC tag and the information acquired by the communication device. The module is executed when the communication device is brought within the proximity of the first NFC tag.
