If the SD Association can work out the disputed issues with Eye-Fi, then the promising new wireless SD card standard should become a reality. If not, Eye-Fi may remain the main game in town. Many top camera manufacturers have special features in some of their cameras to accommodate an Eye-Fi card, which remains a great option for wirelessly transferring photos from digital cameras, but has no capability to receive information from another source.
It would be great to see two-way wireless communication come to any standalone device that supports the popular card but not Wi-Fi.
