WIRELESS PAIRING USING RADIO FREQUENCY IDENTIFICATION COMMUNICATIONS

In an example, radio frequency identification communications is used to pair a wireless device and a host computing system for communications over a non-radio frequency identification communications protocol. The wireless device includes a radio frequency identification reader that extracts pairing information from a radio frequency identification tag of the host computing system. The wireless device may then automatically initiate pairing with the host computing system using the pairing information, without further input from a user of the wireless device. A connection is then established between the wireless device and the host computing system using a non-radio frequency identification wireless communication protocol. The connection facilitates an exchange of data between the wireless device and the host computing system.
