What's FlashAir?

FlashAir is the SDHC memory card with embedded Wireless LAN functionality. Since FlashAir works as a stand alone Wireless LAN access point, FlashAir embedded devices are able to both send files to and receive files from each other. FlashAir also retains the normal functionality of an SD card, allowing general Wi-Fi devices like PCs and smartphones to access its contents.

FlashAir SD cards are available in most countries, and they have been confirmed to work with most cameras and other electronic devices.

Supported devices

Any device with an SDHC slot can potentially host a FlashAir card. This implies that the device must be able to handle SD cards with more than a 2GB capacity. If you have already used an SD card that has a capacity greater than 2GB with your device, the FlashAir card will also function in your device.
