Engadget has confirmed that CSI and MasterCard will launch a mobile payment application for iOS in July of this year. The interesting note is that iOS and RIM are on the list as there are no iPhone or BlackBerry devices with Near-Field Communication (NFC) capability. By gazing into the crystal ball, we assume that the app either won't depend on NFC, or (less likely) both Apple and RIM will release NFC-enabled hardware.
NFC rumors have hovered above the iPhone like so many vultures lately. A recent Bernstein report suggested that the forthcoming iPhone will not offer NFC support.
Regardless, the app is coming. All we've got to do now is wait for it to show up and then see how it works.
