an Eye-Fi card for sale in Tokyo, February 2010

Eye-Fi is a company based in Mountain View, California that produces SD memory cards and SDHC cards with Wi-Fi capabilities. Using an Eye-Fi card inside a digital camera, one can wirelessly and automatically upload digital photos to a local computer or a mobile device such as a smartphone or tablet.

Eye-Fi offer three models, varying in speed, storage capacity, and software services provided.[1][2]


The card is manufactured for Eye-Fi by Wintec Industries Inc. of Milpitas, California, and contains the following major components:


The upload to remote services is via the local Eye-Fi server which has full visibility of the photos and the associated user name and password . The server then uploads to the user's remote storage site and sends the user an email to notify them that the photos have been uploaded to their storage site.

By default, every picture on the camera is wirelessly uploaded to local Eye-Fi servers.[3] Some models also allow for uploading photos to photo sharing, blogging and social networking sites such as Flickr, Picasa, Facebook and PhotoBucket;[4] and some models also allow for uploading videos, both to a personal computer or mobile device and to YouTube.[5]

"Share" versions allow uploading to various photo-sharing websites. The "Share Video" card allows uploading videos as well. The "Pro" adds raw image support and peer-to-peer or ad-hoc networking.[6] The "Pro X2" added class 6 read & write speeds, 802.11n and a new feature named "Endless Memory Mode" that automatically deletes images from the card after they are delivered to their intended destination; all of these have since been migrated to the Connect X2 and Mobile X2.

Pictures are sent from the camera to the local computer using a protocol based on SOAP. This uses an HTTP connection to the server software running on the local computer. Official Eye-Fi server software is available for Microsoft Windows or Mac OS X and enthusiasts have developed server software for other operating systems.

Certain cards offer photo geotagging (WPS) through relationships with Google and hotspot access through relationships with various providers. The location is not locally recorded in conventional Exif coordinate form, but is inserted into Exif upon upload.[7] The Pro X2 ships with both free lifetime geotagging and 1 year of free hotspot access, as did the Explore X2. The Geo X2 offered free lifetime geotagging, but not free hotspot access. Other models can be upgraded (for a fee) to include both features.

Settings of the Eye-Fi card such as wireless network access, selecting upload location on local computer and configuring photo sharing sites is done through software called the Eye-Fi Center which is available for both Microsoft Windows and Mac OS X. Recently mobile access (in beta) has been added via a browser by visiting: http://m.center.eye.fi

Before use of any Eye-Fi card the user must "register" on the Eye-Fi website, in doing so the card software demands the firewall to be opened for the Eye-Fi software,[3] the same happens every time the user needs to reconfigure its wireless network with the network data ending up sent and stored to Eye-Fi servers and that happens by default to every single picture too.[8]


Eye-Fi offers an iPhone app, but it is only available in the US, UK, Canada, Australia, and Japan App Store.[9]


There is also an app available for Android [10] in the Google Play Store: https://play.google.com/store/apps/details?id=fi.eye.android


Under Linux, the EyeFi card can be configured using eyefi-config, which allows viewing the logfiles and changing the wireless settings. To receive images from the card, there are several alternatives, EyeFi Framework, EyeFiServer including a Synology installer (in Python), eyefiserver2 (Python-based), iiid (in C++), RyFI (Ruby based) and Node-Eyefi (NodeJS). However, the UploadKey and TransferMode must still be defined from within Windows/Mac for the first use: although 'eyefi-config -k' has the capability to "print card's unique key", this isn't the UploadKey that is needed.
