BP has announced the national roll out of its new app, BPme, which allows customers to pay for fuel using their smartphone from inside their car without going into the store. The company said the app is intended for those who want to save time at the pump or who are reluctant to leave children or other precious items in their car while they go in-store to pay.

BP added that its site policy on mobile phone usage outside a vehicle has not changed. Customers can continue to safely use their phone (and the app) within their vehicle with the engine off.
