I have an NFC/RFID keychain that looks pretty much like this one:

enter image description here

When I read it with an Android app called "Nfc Reader", it shows me a specific ID (always the same) and it says that these technologies are used: IsoDep, NfcA, NdefFormatable

Now I'm wondering if it would be possible to clone it, or if these technologies somehow prevent it.

The mentioned techologies - compare Android: advanced NFC - seem completely unrelated to the cloneability issue. NfcA is just ISO 14443, type A commnunication, ISODep is communication protocol and NdefFormatable indicates, that reformatting is supported.

Considering this and the fact that none of these technologies addresses some new extended capabilities it still seems a duplicate of the suggested question.
