Flipper Zero, also so-called the Dolphin hack device, revolutionizes the way we perceive portable, multi-functional devices, specifically designed to interact with access control systems. But what can you do with a Flipper Zero?
This powerful gadget not only reads, copies, and emulates RFID and NFC tags, but it also excels in working with radio remotes, iButton, and digital access keys, complete with a GPIO interface. Having made its grand debut in August 2020 via a Kickstarter crowdfunding campaign, it impressively amassed $4.8 million.
Why is Flipper Zero called the Dolphin hack device?
Remarkably, the first devices landed in the hands of backers just 18 months after the campaign wrapped up. A highlight of its user interface is the charming pixel-art dolphin virtual pet. The very essence of this device is the interactivity with this virtual pet, where the use of the device’s varied functions directly influences the pet’s appearance and emotions.

Embedded within its system is an enticing game where the primary objective is to “upgrade” the dolphin by leveraging its assortment of hacking tools. While there are innocuous functionalities like using it as a TV remote or a Carbon dioxide sensor, it’s undeniable that some of its tools hint at potentially unlawful applications.
This includes tactics like RFID skimming, emulation of RFID chips commonly found in ID badges, utilizing the built-in radio cloner to access garage doors, unlock or even ignite smart key-activated vehicles, and acting as a wireless BadUSB.

What can you do with a Flipper Zero?
Let’s delve into the multifaceted capabilities of this device and uncover the myriad possibilities it holds.
Beginner hacking
This Dolphin hack device is equipped to infiltrate an array of systems, from Wi-Fi networks and Bluetooth gadgets to NFC and RFID systems. By intercepting and scrutinizing radio signals, it pinpoints vulnerabilities, positioning itself as an indispensable asset for ethical hackers and those in the penetration testing field.
Educational purposes
The Flipper Zero isn’t just for seasoned professionals; it’s a beacon of knowledge for the curious minds too. Delving into the intricacies of radio frequencies, infrared, and NFC becomes an adventure. Additionally, its programmable nature invites users to hatch their applications, opening up avenues in embedded systems programming.

Car key fob interaction
The device’s sub-GHz wireless antenna is adept at detecting signals from car key fobs. Though it can capture these signals, replaying them to modern vehicles typically doesn’t yield success due to the “rolling codes” system, which alters the code after each interaction.
Engaging with NFC
In today’s world, NFC technology is ubiquitous. The Flipper Zero provides the ability to navigate this wireless terrain. However, a noteworthy mention is its limitation in decoding encrypted security codes on NFC cards, often termed as CSC, CVV, CVC, CAV, among other acronyms.
Reverse engineering
With the Dolphin hack device in hand, one can demystify the tech labyrinth. Flipper Zero offers reverse engineering capabilities, laying bare the heart of various systems. Whether you’re keen to discern the components that power a system, dissect the firmware, or delve deep into hardware reverse engineering, this tool has got you covered.
Unlocking the secrets of RFID
In tandem with its NFC capabilities, the Flipper Zero also masters RFID. For instance, it can effectively read a hotel’s key card. While RFID cards and tags come with a lock mechanism to thwart overwriting, Flipper Zero can sometimes sidestep these barriers, offering the chance to unlock the card when paired with a legitimate reader.

Cracking sentry safe protocols
Surprisingly, the Flipper Zero can also navigate past the defenses of certain Sentry Safe electronic safes, utilizing an output channeled from the GPIO.
Prototyping
Transform your innovative concepts into tangible prototypes with the Flipper Zero. Armed with an assortment of sensors and components, it offers a playground for those eager to craft custom systems or trial groundbreaking ideas. So, the next time someone asks, “What can you do with a Flipper Zero?” you know it’s not just a tool; it’s a realm of endless possibilities.

All-purpose infrared controller
Equipped with an integrated infrared module, the Flipper Zero is versatile. It can command a plethora of devices ranging from televisions to air conditioners. An additional interesting feature is its ability to verify the operational status of infrared remote controls.
Script automation across platforms
Flipper Zero’s chameleon-like trait allows it to pose as a BadUSB device. Upon connection, systems recognize it as a Human Interface Device (HID), akin to a keyboard.
Flipper Zero illegal use cases
While the Flipper Zero boasts a range of practical utilities, it’s crucial to recognize the potential legal pitfalls tied to its use. Let’s dive into some legal challenges users might grapple with.

While the Flipper Zero boasts a range of practical utilities, it’s crucial to recognize the potential legal pitfalls tied to its use. Let’s dive into some legal challenges users might grapple with.
Trespassing digital domains
A glaring risk with the Flipper Zero is its ability to illicitly infiltrate computer systems. Its robust features, spanning Wi-Fi, Bluetooth, and NFC hacking, can exploit system vulnerabilities. Venturing into these systems without due consent isn’t just frowned upon—it’s illegal, and violators could face punitive measures.
Breaching privacy laws
With the capacity to capture and alter radio waves, including mobile signals, the Flipper Zero treads on thin ice. Interactions with this device must remain within the legal spectrum to sidestep potential privacy law violations at both federal and state levels.

Treading on intellectual territories
This Dolphin hack device can potentially override digital rights management (DRM) and other protective barricades set up for intellectual property. Circumventing these protective layers can lead to legal backlash.
Navigating export constraints
The Flipper Zero is ensnared by export control regulations that impose limitations on exporting specific tech goods to particular nations or individuals. Adherence to these laws is non-negotiable to avert legal entanglements.
At its core, Flipper Zero stands as a beacon for tech aficionados and cybersecurity enthusiasts. Yet, with great power comes responsibility. Users should remain well-acquainted with the legal landscape surrounding its use. By harnessing the Flipper Zero within legal confines and steering clear from privacy and property rights infringements, users can safely and lawfully navigate the vast realms of tech, from radio frequencies to NFC. Whether you’re an upright hacker, a tech deconstructionist, or a hardware innovator, the Flipper Zero is an indispensable gem—but wield it wisely.
Flipper Zero’s Amazon ban
Amazon took a definitive step by prohibiting the sale of Flipper Zero, a multifaceted tool prized for education, hacking, and prototype creation. The suspension stems from rising apprehensions regarding the gadget’s potential illicit applications, which encompass unauthorized system breaches and privacy law infringements.
Yet, for enthusiasts, there’s a silver lining: Flipper Zero remains accessible on StockX, a renowned online hub for trading sneakers, urban apparel, and tech gadgets.
