It really doesn't matter what it is. A MicroSD card would be fine for this. Lots of cell phones already have MicroSD slots. The MicroSD card can be put in a USB card reader for USB based machines possibly using a SD card adaptor. A MicroSD card can be put in a SD card adaptor for SD based devices. Pop the existing card out of the phone. Plug it into a card reader and that into the router. The router updates the key ring. You plug the SD card back into the phone and the phone and router can now play.
