I actually think the library that I uploaded also supports Mifare writing. http://www.b4x.com/android/forum/threads/nfc-tagwriter-and-ibeacon-libraries-for-free.42137/#content

can you tell me if it is possible to use the NFCTagWriter right after the Mifare card is read, without having to remove the mifare card and put it again? I am trying to subtract a value every time the card is read. Read is ok. But to write, i have to take the card far from the phone and near again. Is there a workaround for this?
