[Koha] Koha and RFID?

[Katrin Fischer]

I read in the release notes, that Koha Supports SIP2:

>To retrieve and interact with Circulation and Patron data, Koha 3 includes
>support for 3M's Standard Interchange Protocol (SIP2), using the OpenNCIP
>libraries (http://openncip.org).

Is there some documentation besides
http://wiki.koha.org/doku.php?id=en:development:sip2? 

Are there libraries already using Koha and RFID-Tags instead of barcodes
with self checkout? 

Thanks for your help!
