Or you could use a password and generate a keyfile from text stored on the ring.
Ideally, the ring would have to be at least Ultralight C or Mifare plus as they have encryption. (Perhaps a future upgrade)
Another method may be to access an encryption key online via a password and that is used to decrypt sector stored information on the ring.
A simple and immediate boost to security might be to use information contained on your ring now as password padding.
Hi there, I hope this question is not out of line..
Is it possible for users of other rings or RFID products to contribute or perhaps is it possible to have a section created for other products?
There's a lot out there, there are going to be more and this is the only forum I have found. A lot of the questions people would have, such as broken NDEF formatting, lock bits and such are common. In fact, many of the questions I have seen here I can answer myself.
In case there is interest, I purchased a different ring as it has both 13.56 mHz and 125 kHz frequencies.
