The description states that this card is UID rewritable; however, this is not true. I attempted to write a saved UID, which is my apartment key, using my Flipper Zero and the NFC Magic app. After writing, I scanned the card’s UID, and it remained unchanged, confirming that the UID cannot be modified.
