AIUI the way the 'Android beam' feature works is to use the NFC to negotiate a device-to-device Bluetooth connection which then does the actual data transfer. The NFC step is essentially for authentication - on the basis that it's just so short range that you must have deliberately brought the devices close together to do the transfer.
