also it seems like when registering the card with the lock it doesn't write any new data, it just registers its uid I tested and used 2 cards which were wiped and had the same uid and they could both unlock the lock. Both of these "master cards" could register new cards too
when a new guest card is registered it doesn't add any new data
all the cards read as "blank" with the tag reader app so it couldn't be copied with that app
only Mifare classic 1K cards seemed to be accepted, lock doesn't even recognize NTAG215s
clone tests
worked for both guest and master card. Tested this by scanning a card and emulating with flipper and also using flipper to copy card data to a blank magic card.
using 2 master cards
tested this by using 2 wiped magic nfc cards
they had the same uid, registered with one card, but tested and the other one could unlock and register new guest cards
Document what types of tests we will perform on the RFID cabinet lock
