Abstract
Methods and systems for using radio frequency identification ('RFID') to automatically lock and unlock a mobile computing device. An RFID transceiver is installed in connection with a locking device. The locking device can secure the mobile computing device to a cable, which is securable to a physical structure. An RFID transmitter is configured to detect a signal from the RFID transceiver within a predetermined distance range and send a response signal to the RFID transceiver. If the RFID transmitter is within the range, the RFID transceiver detects the response signal from the RFID transmitter and issues an unlocking signal to change the position of the locking device to an unlocked position. If the RFID transmitter is outside of the range, the RFID transceiver does not detect a response signal from the RFID transmitter, and issues a locking signal to change the locking device position to a locked position.
