This has been a pain in the butt for me, but for CFE I can see that it was "smart." I have noticed that new homes in my area (Riberas) are getting the old style meter. My sense is that the smart meter plan didn't last long as when I stand in line at the machine (CFE itself being the only place I can pay) I rarely see another person with a card.
Does anyone know what the status is of that plan to convert meters to the digital ones that use the smart card?
