NRF52 nfc tag unique data.

[sjheo]

hi, i'm using nrf52-dk (nfc example) with android nfc reader app.

I heard that the nfc tag has a unique id.

But, other tags in the same module have the same ID. (In fact, I do not know if this is an id. reader show 7 - byte data)

Is right the nfc tag data different for each tag? or each dk?

How can a reader read if it is a tag?

Thank you..

The nfc tag is an antenna only, nfc id is in RAM..
I did not know that I was studying now.
