Hi there. I know some keys that can give you access, for example, to the main door of the building and then to a certain floor. Can flipper write it that way? I don’t see how cuz if you try to do it twice the second writing will just overwrite the first one, isn’t it? Will appreciate making it clear.
Assuming the doors are 125KHz RFID, access is determined by the reader. The card only has one identity and your card is on the access list the reader has or it is not.
yup, 125, thanks for the answer
