A system comprising: a transceiver (102, 112, 114) that is passive and unpowered and that includes an antenna that is configured for receiving an RF wake up signal from a wireless communication device, the transceiver also including a directional coupler and a RF detector for converting a received RF wake up signal to DC pulses; and a processor operatively connected to the transceiver and to a memory, wherein the memory includes instructions recorded thereon that, when read by the processor, cause the processor to: detect an interrupt by the DC pulses when in a sleep mode; partially awake to analyze the detected DC pulses of the wake up signal to determine if the wake up signal is valid; wherein the processor transitions from a sleep mode to an active mode upon validation of the wake up signal to activate and power up the remaining components of the system if the wake up signal is valid; wherein the processor returns to sleep mode if the wake up signal is invalid; the remaining components of the system include a BTLE transceiver that is operatively connected to the directional coupler and is arranged to establish a link with the wireless communication device, communicate through the directional coupler and antenna that the wakeup signal has been validated, and prompt a user of the wireless communication device to enter an access code; wherein an access code entered by the user is received by the antenna and passed through the directional coupler to the BTLE transceiver, which demodulates the access code and presents it to the processor for verification; wherein the processor is arranged to, upon receiving the access code compare the access code with a stored code using memory and the processor is arranged to, if the access code is valid, send a lock/unlock signal to a locking mechanism. a transceiver (102, 112, 114) that is passive and unpowered and that includes an antenna that is configured for receiving an RF wake up signal from a wireless communication device, the transceiver also including a directional coupler and a RF detector for converting a received RF wake up signal to DC pulses; and a processor operatively connected to the transceiver and to a memory, wherein the memory includes instructions recorded thereon that, when read by the processor, cause the processor to: detect an interrupt by the DC pulses when in a sleep mode; partially awake to analyze the detected DC pulses of the wake up signal to determine if the wake up signal is valid; wherein the processor transitions from a sleep mode to an active mode upon validation of the wake up signal to activate and power up the remaining components of the system if the wake up signal is valid; wherein the processor returns to sleep mode if the wake up signal is invalid; detect an interrupt by the DC pulses when in a sleep mode; partially awake to analyze the detected DC pulses of the wake up signal to determine if the wake up signal is valid; wherein the processor transitions from a sleep mode to an active mode upon validation of the wake up signal to activate and power up the remaining components of the system if the wake up signal is valid; wherein the processor returns to sleep mode if the wake up signal is invalid; the remaining components of the system include a BTLE transceiver that is operatively connected to the directional coupler and is arranged to establish a link with the wireless communication device, communicate through the directional coupler and antenna that the wakeup signal has been validated, and prompt a user of the wireless communication device to enter an access code; wherein an access code entered by the user is received by the antenna and passed through the directional coupler to the BTLE transceiver, which demodulates the access code and presents it to the processor for verification; wherein the processor is arranged to, upon receiving the access code compare the access code with a stored code using memory and the processor is arranged to, if the access code is valid, send a lock/unlock signal to a locking mechanism.
