Analysts at research firm CCS Insight said that this may "hamper acceptance by operators" who will not be able to charge for a separate data connection for the device.
The three handsets on Verizon's LTE lineup now offer dedicated back covers to lead the charge (pun intended) to general consumer acceptance, and dozens of other companies are working to integrate inductive charging surfaces into everyday items like furniture, desktops, or the middle of your car.
Also, unlike Visa and MasterCard, American Express only issues charge and credit card products but not debit cards, which have been gaining widespread acceptance over the past couple of years.
