This script was based on the python script by NFCToys. It was painstakingly debugged over a 4 day period and then re-coded into this web-ready version for ease of use.
In order to use the app you are required to have the Item Name and UID of the NFC product you wish to decode.
It was originally developed to work alongside the Flipper Zero, which natively will not include the necessary keys to decode certain NFC figures.
This software cannot be used to determin keys without the correct UID for NFC figures you own. If you are unsure how to find the UID of your NFC figure then please check the Flipper Zero forums for more info.
