    by data card I assume you mean network card, sao that would could be used for internet yes with a wire. The Wifi is the same thing but wireless so yes it can access hotspots.

      Many laptops now are coming with a 3G Data Card slot (mobile broadband), allowing direct access to the internet over a moble network (e.g. Vodaphone).

      This is different to WiFi in
      a) the speeds (typically up to 2Mbps in the UK where WiFi is up to 54+Mbps)
      b) the cost (something vs nothing)
      c) exposure (WiFi is to a LAN, 3G is directly to an ISP)
      d) spread (WiFi is in hotspots only, 3G is fairly widely spread -- anywhere you can get a decent mobile signal)

      I don't know if this is what you ,mean by a "data card" ?
