The question "How can I check if I'm near an ATM?" comes up a lot in FiveM scripting chat.

near-atm.lua

local maxDistance = 1.0
local IsNear = false

AddEventHandler('near-atm-distance', function(distance)
    maxDistance = distance
end)

Citizen.CreateThread(function()
    while true do
        Citizen.Wait(0)
        local coords = GetEntityCoords(PlayerPedId())
        if DoesScenarioOfTypeExistInArea(coords.x, coords.y, coords.z, "PROP_HUMAN_ATM", maxDistance, false) then
            if not IsNear then
                TriggerEvent('near-atm', true)
                IsNear = true
            end
        elseif IsNear then
            TriggerEvent('near-atm', false)
            IsNear = false
        end
    end
end)
