you may check some Nissan forums for this info. Most newer Nissan's (at least the Altima's and Maxima's) are just like this. Get in, sit down, push the button to start the car. No need to take the key out of your pocket.
They may give you the info you need as to what tech they are using. For bluetooth, the PC would have to be on already and you'll probably also need a security bypass box (had to have one installed into my Maxima for the remote start). Not sure about RFID but I would assume the same.
