Gamepass ain't working ?

The BadgeService is used to award a player a badge or to check if a player has a badge. It does not check if a player has a Game Pass or not.

In order to check if a player has a Game Pass, you use the MarketplaceService. Instead of using UserHasBadge, you would use PlayerOwnsAsset. An alternative way is to use the GamePassService along with PlayerHasPass, although this is not recommended because PlayerHasPass caches the result of the function so the player won't get the tool if they buy the tool in-game.

tool = game.ReplicatedStorage.Tool

game.Players.PlayerAdded:connect(function(player)
    local allow = game:GetService('MarketplaceService'):PlayerOwnsAsset(player, 289963623) --We use the MarketplaceService and PlayerOwnsAsset here instead of BadgeService and UserHasBadge
    if allow then
        local Clone = tool:Clone()
        local Clone2 = tool:Clone()
        local Backpack = player:WaitForChild("Backpack")
        local StarterGear = player:WaitForChild("StarterGear")
        Clone.Parent = Backpack
        Clone2.Parent = StarterGear
    end
end)
