The Nintendo 3DS eShop was added in the June 2011 Update for JP/EUR/USA.

From here you can download Virtual Console games, 3D Classics, DSiware software, view screenshots and 3D trailers for upcoming 3DS titles.

When connecting to the servers, eShop requests from these domains over HTTPS: nus.c.shop.nintendowifi.net, ecs.c.shop.nintendowifi.net, cp3s-auth.c.shop.nintendowifi.net, cas.c.shop.nintendowifi.net, and a248.e.akamai.net.

EShop QR Codes

Eshop QR Codes can be scanned with the camera, allowing one to quickly navigate to the desired eshop title with just two clicks. The QR Codes itself is a simple text/url QR, started with "ESHOP://" string followed by a eshop title link id and then some special data, delimited by a dot symbol, which can be ommited.
