Hi,

Thanks for the reply.

Now I can read and write the data with different type but same manufacturer such as MIFARE Ultralight & NTAG213/215/216.

Still I am trying to read & Write with the Mifare Classic 1K.

I want your suggestion such that in my PCB layout, I am trying to put all the RF chip and components will be at center of the antenna. So that I can get more space. If I seen the CR95 Eval board the antenna part is separate and no other components also placed at the bottom and inside the antennal tracks.

This above type of placement is recommended?

Will you share the PCB guidelines for the CR95H...

Kind Regards,

Nishanth M
