I want this door to only open with a keycard, it opens with an arm though. How to fix?

The door is supposed to only open when the keycard touches, but it's also opening with a player's arm. How do I stop this? Here is the script:

							--<tkcmdr>--

local door = script.Parent
local bool = true
local bool2 = true
local clearance = {
	["Omni"] = true,
	["MTF"] = true,
	["L5"] = true, 
	["L4"] = true,
	["L3"] = true,
	["L2"] = true,
	["L1"] = false,
}

function openDoor()
	script.Parent.DoorOpen:play()
	for i = 1,(door.Size.z / 0.30) do
		wait()
		door.CFrame = door.CFrame - (door.CFrame.lookVector * 0.30)
	end
	wait(3)
	script.Parent.DoorClose:play()
	for i = 1,(door.Size.z / 0.30) do
		wait()
		door.CFrame = door.CFrame + (door.CFrame.lookVector * 0.30)
	end
end

script.Parent.Parent.KeycardReader1.touched:connect(function(touch)
	if touch.Name == "Handle" and clearance[touch.Parent.Name] and bool then
		bool = false
		script.Parent.AccessGranted:play()
		script.Parent.Parent.Light1.brickColor = BrickColor.new("Bright green")
		script.Parent.Parent.Light2.brickColor = BrickColor.new("Bright green")
		openDoor()
		wait(1)
		script.Parent.Parent.Light1.brickColor = BrickColor.new("Bright red")
		script.Parent.Parent.Light2.brickColor = BrickColor.new("Bright red")
		bool = true
	elseif touch.Name == "Handle" and not clearance[touch.Parent.Name] and bool2 then
		bool2 = false
		script.Parent.AccessDenied:play()
		wait(1)
		bool2 = true
	end
end)

script.Parent.Parent.KeycardReader2.touched:connect(function(touch)
	if touch.Name == "Handle" and clearance[touch.Parent.Name] and bool then
		bool = false
		script.Parent.AccessGranted:play()
		script.Parent.Parent.Light1.brickColor = BrickColor.new("Bright green")
		script.Parent.Parent.Light2.brickColor = BrickColor.new("Bright green")
		openDoor()
		wait(1)
		script.Parent.Parent.Light1.brickColor = BrickColor.new("Bright red")
		script.Parent.Parent.Light2.brickColor = BrickColor.new("Bright red")
		bool = true
	elseif touch.Name == "Handle" and not clearance[touch.Parent.Name] and bool2 then
		bool2 = false
		script.Parent.AccessDenied:play()
		wait(1)
		bool2 = true
	end
end)

Your keycard script doesn't seem to have any problems, and because of that I will assume that the reason you think your keycard is opening to peoples arms is because the keycard is actually bigger than you think. I would suggest resizing the Handle part in the keycard to something smaller than what it is and then giving it another shot.
