SnapTag automatically identifies and classes devices for you, and presents that in the Scan.Device property. Unknown devices are classes as System.XTrak.Device.Unknown.
Generally we recommend using a switch statement to group and process responses, however you'd like.
switch (Scan.Device)
{
case Sygnal.XTrak.Device.iPhone:
case Sygnal.XTrak.Device.iPad:
case Sygnal.XTrak.Device.iPod:
case Sygnal.XTrak.Device.Android:
Response.Redirect ("http://m.snaptag.co.nz");
break;
default:
Response.Write (Scan.Device.ToString());
break;
}
