Powermat to Upgrade Starbucks Charging Mats to Support iPhone X

How are Powermat chargers upgradable by software? There's no connection to Starbucks wifi or Ethernet to them. In fact they're barely working half the time anyway. They got rid of all the power rings cause no one ever returned them. I fail to see how they're going to upgrade these via software on a whim. They're gonna have to just replace them. PMA was always a crap idea against Qi anyway.
