Still Don't Use This RFID Writer With Kyber Crystals

Several months ago I uploaded a video about the ZX-Copy3 and why you should absolutely not use that RFID writer with kyber crystals. The main reason being it installs an unknown password onto your RFID tag which prevents you from reprogramming that RFID tag with any other programmer. You can watch that video here: https://www.youtube.com/watch?v=HbGtDmEfwwo

The password is no longer unknown.

For T55xx RFID tags, the password is: 19920427
For EM4305 RFID tags, the password is: 84AC15E2

Despite now knowing the password, I still do not recommend using this writer. It’s possible that you will receive a version of the writer that uses a different password. It’s also an expensive RFID writer and its software feels unfinished. In fact it tells you when you try to use one of its main 4 functions that particular function is not yet available, but will be in some sort of future update (which has yet to materialize).

The EM4305 Datasheet, from which I included a couples pages in this video, can be found online here: https://www.emmicroelectronic.com/sites/default/files/products/datasheets/4205-4305-DS-01.pdf
