I have been reading an interesting post from Springwise (one of my sources of innovation inspiration, by the way) which points the way to an ever greater role for the smartphone in our lives. Navigo is shortly going to be trialling a service in Paris which will allow travellers with NFC enabled smartphones to pay for their tickets with their phones. NFC is already in some Android phones and the chances are the iPhone 5 will incorporate the technology too. Is this the beginning of the end for the wallet.
