NFC tag model

Hi everyone!

What type or model do you use with web-nfc
https://cs.chromium.org/chromium/src/third_party/WebKit/Source/modules/nfc/
?
The one I bought seem not functioning. Is there a specific instructions to
run it or my NFC just not doing it's job. LOL. What NFC tag do you people
use?
