"Bitcoin for Individuals
Bitcoin is the simplest way to exchange money at very low cost.
Mobile payments made easy
Bitcoin on mobiles allows you to pay with a simple two step scan-and-pay. No need to swipe your card, type a PIN, or sign anything. And all you need to do to receive Bitcoin payments is to display the QR code in your Bitcoin wallet app and let your friend scan your mobile, or touch the two phones together (using NFC radio technology)."
