Automatic Door Hand-free Access RFID Electronic Tag in Car
The M-518 Series is an advanced Smart RFID Tag system designed to provide authorized vehicles with completely automatic, hands-free entry through automatic doors and gates.
By pairing a compact receiver installed on your door controller with a USB-powered tag placed in the vehicle, the system enables a smooth, stop-free access experience within a robust 30-meter sensing distance. Ideal for factories, warehouses, home garage, private villa and commercial facilities, it enhances both security and operational efficiency.
True Hands-Free Vehicle Access: Authorized vehicles trigger the door to open automatically upon approaching within the preset range. No need for remotes, cards, or manual buttons.
Automatic Closing: The door automatically closes after the vehicle has departed and moved beyond the response distance, ensuring security and energy savings.
Long & Adjustable Sensing Range: Reliable up to 30-meter operating distance. Customize the activation range with 6-level distance adjustment to prevent false triggers.
Mobile Phone Control: Equipped with a mobile phone APP that allows you to open the door remotely via your mobile phone.
