Cross-platform automated perimeter access control system and method adopting selective adapter

A selective adapter adapted for use together with an electronic lock having a second wireless communication reader therein and a sensor area thereon, comprising:

• a wireless communication conversion unit, comprising:
• an on/off switch;
• a first wireless system on chip (SoC);
• a second wireless system on chip (SoC);
• and
• wherein the wireless communication conversion unit is configured for receiving a wireless transmission signal and operating under a first wireless communication platform and a second wireless communication platform, the first wireless communication platform is different from the second wireless communication platform, the first wireless SoC is coupled to the on/off switch, the on/off switch is coupled to the second wireless SoC, the first wireless SoC turns on the second wireless SoC using the on/off switch, the first wireless SoC selectively determines whether to allow the second wireless SoC to transmit the wireless transmission signal after performing a digital certificate authentication procedure, the selective adapter is installed above the sensor area of the electronic lock to facilitate interrogation thereof by the second wireless communication reader in the electronic lock.
