SD memory cards with built-in Wi-Fi appeared for a long time. I learned that we can buy and was surprised by what we found.
Map with WIFI allows you to transfer photos and videos from the camera to a smartphone or a computer (or vice versa, to upload music to the player) "on air "without connecting cable, and can work in all devices, including those that do not have wireless modules.
The first such card company released Eyefi, then the card with WiFi produced Transcend, Sandisk, PQI.
Now I could not find on sale in Russia or one card with support for WiFi. Looks like they're all out of production.
On Aliexress have three and a half model of SD cards and adapters with support for WiFi. The most common ez Share. These come in the form of an SD card, and as adapters for regular MicroSD card and are from $ 16.
There ez Share first and second generation. The first supports only photos, the second different types of files, well, all of these devices have a huge disadvantage: they can only work as an access point. Connect the card to your home network, or networks, to distribute a smartphone, will not work and it is necessary each time to switch to a WIFI-network created by the card itself.

The same problem and Toshiba Flash Air, the 32-gigabyte version of which can be found for $ 25.84.
They added, "crutches" in the form of a through-connection when the card is connected to a router, and a smartphone or a computer connected to the map, but it is also inconvenient, especially in home use. Overview Toshiba Flash Air: mysku.ru/blog/ebay/63892.html
The cheapest and perhaps the best SD-adapter with WIFI is available at a price from $ 14.56. He is nameless.
Unlike the previous two adapter can operate in two modes - as an access point, and as an ordinary device connected to the WIFI-router. But here was not without serious drawbacks: only supported Android devices and iOS, and does not work with your computer.

In general, to transfer photos and videos from the camera to a smartphone in the way these devices will do, but for the easy transfer of data at home, they are not suitable (and the rate of small and inconvenient to connect).
