Chhavi-An open source security device |vicharak|KCK Market
CHHAVI – A novel approach to access and identity!
As the world becomes increasingly digitized, the need for strong security measures becomes more and more important. Hundreds of millions of devices all over the world rely on biometric solutions.??That's why we're excited about Chhavi, a tiny capacitive type sensor that offers all the features you need to keep your data safe.
Chhavi is a compact, wireless, touch-capacitive fingerprint sensor based on ESP32 WiFi and Bluetooth SoC. It's offered with optional NFC connectivity and a battery, making it a great choice for a wide range of applications. Best of all, it comes with open source firmware so you can customize it to your needs.
With its low power consumption and high end security features, Chhavi is the perfect solution for your security needs. So why wait? Get yours today!
CHHAVI – A key to every solution!
The saying goes, "never trust, always verify." But what does that mean? There are as many methods to combine algorithms, sensors, and other components as there are to incorporate.
Introducing Chhavi, the world's smallest and most advanced fingerprint sensing module! Our design process took into account key factors such as accuracy, size and power consumption, and we believe that Chhavi is the perfect solution for secure access control and other applications. With integrated WiFi, BLE/BT, USB and fingerprint sensing, Chhavi is the perfect all-in-one solution and this all-in-one design makes our module very versatile and easy to use for your next project!
What makes Chhavi special?
When it comes to choosing a fingerprint sensor, there are a lot of things to consider. But one of the most important factors is specifications.If you're looking for great specs, the Chhavi is definitely one to consider. So, what are the specs of the Chhavi?

Chhavi with optional NFC:
NFC communication has been around for years, but we could not find a major ESP32-powered NFC controller. This is why we decided to build a standalone NFC controller system that naturally fits into Chhavi.As a consequence, you get a little gadget with a cutting-edge fingerprint scanner, Wi-Fi and Bluetooth connectivity, plus support for NFC and battery power if needed.
Chhavi with open source library:
Chhavi comes with an open source library that makes it easy to program using Arduino IDE. And because it includes a built-in USB-to-UART adapter, you can program the ESP32 module right out of the box.?
Do you prefer working with Espressif’s ESP-IDF framework??We have the library for that as well!?
?You'll need to check it out in order to successfully interact with the Arduino, ESP-IDF, WiFi-to-UART, Bluetooth-to-MIDI, and Ethernet adapters in Arduino IDE.
?Despite its small dimensions of 26 x 26 x 9 mm, Chhavi is jam-packed with useful functions. It incorporates, for example, a vibration motor that gives immediate haptic feedback in the case of a successful or unsuccessful fingerprint scan (or that you can re-purpose for other applications as needed). In addition to an MCU reset button, Chhavi has an easy-to-use on/off switch that lets you save power when it's powered by a battery. (If you don't require this feature—say, if it gets power through USB—you may use that interface as a GPIO instead.)
Application areas where Chhavi is used!
Because of its wireless, distant low power, and NFC characteristics, Chhavi is helpful in a variety of fingerprint sensor applications. Chhavi is ideal for PC security applications such as password managers and local authentications, as well as battery-powered remote systems, a broad range of locking systems, and even attendance/personnel management systems, to mention a few.
Few use cases as follows:
Chhavi is becoming more and more integrated into our daily lives, whether we realize it or not. As time goes on, the usage of chhavi will become more common, and many of us will rely on them to get access to a variety of products and services that we use on a daily basis.
?Chhavi- Bigger Impact on IoT technology in future!!
The emergence of Internet of Things (IoT) enabled gadgets in the workplace is one of the most difficult tasks for security departments. Despite significant progress in recent years, security for these devices remains a persistent problem for both manufacturers and cyber security organizations.
As we wait for potential answers, we the security professionals are turning our focus to biometric security solutions as a means of securing IoT devices, assisting in the security of their networks, and limiting the potential backdoors generated by IoT linked devices.
And we can see, the integration of biometric technology into IoT linked devices is already happening, and it will continue to develop in the coming years as organizations seek to address the potential hazards posed by unprotected IoT devices on their network.
