I am thinking of buying a paypal mobile credit card reader for use in the bunkhouse I manage. However, the bunkhouse is on a remote island and mobile reception is a problem (i.e. lucky to get any signal). From reading the desrciption of how the card reader works, I am confused as to whether only wifi is needed (we have good wifi) or if we need to have a good phone reception as well. Any help on this subject would be much appreciated.
