in pets, open and close some garage doors, and, until Apple issued 
a patch, send iPhones into a never-ending DoS loop.
The Flipper Zero can unlock some <a href="https://theflipperzerozone.com/Flippers-0---Revolutionizing-Hacker-Strategies.html" rel="nofollow">rfid fuzzing flipper zero</a> cards and tags.

You have radios for emulating remote controls, an RFID reader, 
infrared transceiver, and even GPIO pins. It can do all sorts of things, from emulating RFID and 
NFC cards, to analyzing radio protocols, imitating remote controls, and much more.
The price and ease of use make Flipper Zero ideal for beginners and 
hobbyists who want to understand how increasingly ubiquitous communications protocols such as NFC and 
Wi-Fi work. The Flipper Zero is the ultimate multi-tool for pentesters, geeks, ethical hackers and hardware hobbyists alike.

In short, the Flipper Zero wants to be something like a higher-level Raspberry Pi or Arduino for hackers, one 
that serves the hardware in a more easy-to-use package with an element 
of gaming on top.
