1. Testing car key fobs, wireless doorbells and more

The sub-GHz wireless antenna can pick up signals from devices such as wireless doorbells and car key fobs, making the Flipper Zero a handy tool for testing if wireless transmitters are working properly. I use mine to test if the fobs are working and to test their range.

Flipper Zero can record the codes transmitted by car key fobs, but retransmitting these codes to a modern car won't unlock it due to a feature called 'rolling codes' that changes the code with each use. On older cars(those 20 years old and more) you could use a code captured to unlock the vehicle (but don't do that unless it's your car or you have permission!), but you still couldn't drive away with it.
On the flip side, pun intended, retransmitting the codes to a wireless doorbell will cause the bell to ring, as most of these systems don't have a mechanism to protect against such annoyances.

 

2. Reading/saving/emulating NFC

NFC is everywhere nowadays, and the Flipper Zero allows you to work with this wireless protocol. It's built into plastic cards and fobs and used for all sorts of things, from unlocking hotel room doors to controlling barriers.

But this doesn't mean you can cause chaos in the world, because to unlock things you more often than not need access to the NFC key.

NFC signals can be read by the Flipper Zero, and many NFC cards can also be copied and cloned (this depends on the security used for the card, so I can't give you any hard and fast rules about which NFC devices can be cloned). I've used my Flipper Zero to copy my hotel room card on occasion when the hotel only gives you a single card or when we have multiple rooms and don't want to juggle a handful of cards.

 

3. Reading and unlocking RFID tags and cards

RFID cards and tags can be locked to prevent them from being overwritten or having their security keys extracted, but the Flipper Zero can bypass many of these mechanisms. For example, it can offer to unlock the card if you present it to a valid reader (such as the lock it has been programmed to open). This allows you to clone the card and unlock the door using both the card and the Flipper Zero.

 

4. Universal infrared remote control

The Flipper Zero has a built-in infrared module that can be programmed to operate a wide range of devices, from TVs to AC units. Pretty much any consumer device with an IR remote control interface can be controlled using the Flipper Zero.

Another cool use of this functionality is to test if infrared remote controls are working. Simply point the remote control at the Flipper Zero in 'read IR' mode, and it will detect the signals. I use this feature all the time to test remote controls that I've fixed after battery leaks have damaged the device. It's an incredibly handy feature!
