The answer is Google. Yesterday the world was officially introduced to Google Wallet a new App that will eventually be included in all Android based devices. Google Wallet is currently only available on the Nexus S 4G but will become widely available as more devices are produced. The basis of the Google Wallet App is the ability to use a NFC (Near Field Communication) Chip that enables you to use your device as a credit card at locations which have a pay pass system installed. That is the first problem I can foresee at this point is that not many places have pay pass's available. The second problem is that you need a credit card. Well there's a solution for that as you can use prepaid cards and top up when you want. Check out the announcement video below. I have also provided a link (bottom picture below) to a Blog Entry with a much more detailed analysis done by the dudes over at Engadget who spent a week toying with Google Wallet.
