More information about Jewel Topaz tags

Dear user,

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
