US Patent 9148202 RFID-based communication devices and methods for location-based entertainment systems

An interactive entertainment system using radio-frequency identification (RFID) technology to allow participants to communicate user input to the system. The system includes an interactive station including an RFID reader and wireless communication devices that each has a user input portion operable by a user. Each communication device includes an RFID assembly that operates to broadcast to the RFID reader tag data, which is selectable by a user by operating the user input portion. The RFID assembly may use passive RFID tags that are activated or operable in response to user input such as pressing a button associated with an RFID tags, which causes the RFID tag to be read by the RFID reader to obtain a button ID. The RFID assembly may include an active RFID tag and a computing device that selectively modifies tag memory based on user input to communicate user messages to the RFID reader.
