Supposedly we're getting some equivalent to google wallet, called Isis or something like that. There was a thread on it.
What I wanna know is could I copy my "Smartcard" for our local tram system and then use my phone in its place, one less thing to carry. The NFC chip can read it, but I dont know how to make it re-broadcast it(I assume host devices can act as clients?).

I use it to replace my tram / subway card ( not sure if it's legit ) and sharing contacts. Also, Bump.

I have a public transport card and it would b nice 2 copy it.
NFC Taginfo app (free in market) shows:
and
The best thing that my work ID card is NFC...
So how can I copy cards to XS and use it on it?

There is a lot of information on Mifare, but it's in the grey zone, so I won't link directly. Google it.

That's not much help, is it? Yes, there's lots of information on Mifare, but you seem to be claiming that you're using your phone to emulate your physical cards. From what I understand of Android, that's not possible at this time (card emulation).

I'm not emulating. I use the protocol to report a fixed value and all the calculation is done on device.

what "gray" is in copy MY public transport card or my work's ID card?
if someone break the law then this is a gray zone. if I copy my work ID card or my CD it's my privilege

Another use for NFC is the ability to easily establish a connection/share credentials for Multiplayer games or file sharing, as a user you wouldn't need to bother enabling bluetooth or wifi and connecting with the other device or typing its IP address, you would just have to put the two devices side to side and the software would automatically exchange the IP address or establish the bluetooth connection
