I used the methods described in this document:
http://www.nfc-reader.com/NFC-smart-car … ACR122.pdf
on page 19 for Topaz tags with the difference that I send only bytes starting with 0x01 or 0x53 and beyond.
For example if the required sequence for reading block 8 from the tag is as follows:
FF 00 00 00 05 D4 40 01 01 08
I skip bytes
FF 00 00 00 05 D4 40 01
and send only bytes
01 08
Similary for writing to the tag the required byte sequence for writing to block 8 is as follows:
FF 00 00 00 06 D4 40 01 53 08 FF
I skip bytes
FF 00 00 00 06 D4 40 01
and send only bytes
53 08 FF
I can read and write mifare ultralight tags, but as I managed to see that the initial sequence for sending a read command is identical but differs for a write command in fourth byte (15 for mifare tags and 06 for topaz) so that might be the problem when writing topazm, but it shouldn't be a problem when reading it because the sequences are the same.

I also must mention that I can successfully identify that topaz tag was used on the reader, I just can't read or write the data from it.

On the main website I was trying to expand the information about jewel tags.
They are often referred to as NFC Forum Type 1 tags.

This tags are compatible to modulation described in the ISO14443-A. But in general they only support the ATQA frame. In this frame the flag for proprietary protocol is set and is followed by a custom (non-public?) protocol.

Since I'm very interested in learning about new tags I hope someone can supply me one of these tags.
Please contact me if you can help me out.

Thanks a lot in advance, cheers,

  Roel
