I use a MIFARE Classic badge to access my building (the system is a French one: VIGIK).

I cloned a few tags already (tag to tag) and was wondering if my Galaxy S22+ with Android 13 could act as a tag, replacing the physical one? (I would like to possibly extend the answer to "any phone that supports NFC" if this is possible)

I read all kinds of things about this (notably Host-based Card Emulation, but also this answer from 2012) but in none of the discussions I saw a concrete answer to the question above for 2023 phones and Android version.

  • There's an answer posted in 2019 mentioning the impossibility of emulating/modifying sector 0, which is the UID (identifier). Otherwise, both the Reddit thread and an answer to the linked question mentioned that rooting is needed to touch the UID.
