The contactless systems provide almost zero added user
convenience. They're a nice marketing hack by the RFID crowd, but
nearly nothing more. Users do not mind withdrawing a token from their
wallet and inserting it momentarily into a reader.
However, the contactless systems also provide a nice new mechanism for
fraud, and with the increasing feasibility of phased array systems,
that fraud may soon be possible at considerable distances.
So, we've gained very little, other than a nice new app for RFID (RFID
being a large scale solution waiting for problems), but at the same
time we've lost quite a bit.
