Abstract: RFID-to-Bluetooth selective adapter with multiple RFID integrated chips mounted on RFID elevator controller, having customized RFID transponders, a bluetooth module, and an extended I/O connector is disclosed. Customized RFID transponders include RFID Integrated chips, RFID sensor coils, and a SPNT switch. Extended I/O connector is configured to allow connection of customized RFID transponders by coupling to SPNT switches. Bluetooth module instructs which one of SPNT switches is to be opened or closed, which then connects one RFID sensor coil with one corresponding RFID Integrated chip, while other RFID sensor coils and remaining RFID Integrated chips are disconnected. Selection criteria of chosen RFID IC by Bluetooth module is in accordance with preconfigured allocated access right given to each user by an administrator and is programmed on flash memory, EEprom memory of Bluetooth module, in APP, or on cloud authentication server. More than one customized RFID transponder can be chained together.

Abstract: Short-range and long-range operating methods for hospitality accommodation automation and control using APP, webpage, smartphone, RFID-to-Bluetooth selective adapter, relay controller together with RFID door lock is disclosed, where unlocking RFID door lock requires just pressing a button, various power outlets, lighting levels, HVAC settings, and tv settings can be controlled by smartphone. A gateway device with internet connectivity allows remote unlock or lock of doorlock, sending notifications of door unlock events back to a cloud server, and remotely control electrical or electronic devices under short-range or long-range modes. Detection methods for determining whether any occupant remains inside the room is also included. Current sensor is used for assess electric power consumption rate.
