When we first started designing a small, wireless module for universal fingerprinting applications, we did not think to include NFC capability. Our goal was to provide a device with smartphone-level speed, precision, and reliability, as well as capacitive touch support so the ESP32 at its core could be awakened from deep-sleep mode when needed. That gave us a low-power, battery-capable fingerprint module with the ability to communicate over Wi-Fi or BLE. Then came USB support for PCs. Then came NFC. And now here we are! Chhavi is an easy-to-use, all-in-one, ESP32-powered module ready for whatever wireless fingerprinting application you might have in mind. Come check it out! Read the full update.
