    Smile which block of the mifare1k or 4k card does the nokia nfc6131 access

    hi..
    i tried to send a contact/call request/bookmark and a message to a mifare 4k card using the nfc option of the nokia6131 nfc phone menu..
    i was able to transmit to tag successfully...
    and the phone was also able to detect the content of the mifare 4k (contact/call request/bookmark) when the tag was brought near the phone and when the tag detection was switched on in the phone...

    and also at a time only one data is stored on the mifare4k card.. i.e.. i am able to write either one contact or a book mark or a call request...

    its not possible to write multiple data/contacts onto to the 4k card...


    also the SimpleNDEF program of the nfc sdk works fine with the mifare 4k card..

    but i want to know as - "To which particular location on the mifare card does the phone write/read or access .. which particular block of the 4k card is written... " and is it possible to store multiple contacts on to the card using the 6131 phone...

    pls provide info...

    also provide other sample application codes to work with the nfc 6131

    The embedded software on the 6131 NFC uses only the first NDEF record it finds
    from the card. So even if the the card contains multiple contacts only the
    first one is imported by the phone. You can, however, write your own midlet
    that handles multiple records.

    Which blocks are used is probably not important in this case. You should
    use NDEFMessage/NDEFRecords to handle this type of card.
