I have been looking into nfc on the android platform, I have a few RFID tags laying around but they dont want to interact with the nexus s. i believe that the tags arent supported by the andriod nfc module (I can for example read my old card of college, which is mifare classic). for reference I have linked to a webstore selling these things. Is it possible to use these tags with android? Will it be a lot of coding/hacks?
here is a link to the rfid tags: http://www.parallax.com/StoreSearchResults/tabid/768/txtSearch/tag/List/0/SortField/4/ProductID/693/Default.aspx
any guidance is appreciated
The tags you link to operate on 125kHz. NFC operates on 13.56MHz, so it is incompatible with your tags. There is now way a software hack can overcome this.
