General Motors subsidiary OnStar is experimenting with NFC to initiate payment at public charging stations for electric vehicles.

As more electric vehicles arrive on the market the demand for public charging will grow, as will the need to know how much charging away from home will cost, points out Onstar.

The company's Park-Tap-Charge smartphone app is designed for use at charging stations where there is a usage fee, to address possible customer anxiety by telling them in advance how much a top-up will cost. It will allow electric vehicle owners to tap their smartphone against a charging station, which will automatically show payment options that, once accepted, will initiate the flow of electricity.
