You might recall that earlier this year, we told you that a number of Euro McDonald's were going to offer wireless charging to customers through the PowerKiss systemwhich works with Qi supported phones. Those with a Qi enabled device just need to place it on the table to recharge. Those with a device that doesn't support Qi can plug in the PowerKiss ring into the earphone jack to allow them to recharge wirelessly.
