Tested and working 16GB SD card with Wi-Fi function, eyefi mobi model. - Brand: eyefi - Model Name: mobi - Capacity: 16GB - Function: Wi-Fi wireless function (service currently discontinued) Thank you for viewing. This item is no longer used due to the end of the eyefi service, but it still has the standard SD card functions. Official eyefi support has ended. You may be able to find instructions by searching online for "eyefi manual config," but I don't have detailed information, so this is for those who can troubleshoot on their own. Thank you.
