Smart Ring with Embedded RFID Chip for Data Security

The Smart Ring project operates on the principles of Radio Frequency Identification (RFID) technology, utilizing a passive RFID chip extracted from a standard plastic card and embedded into a custom-designed 3D-printed enclosure. A passive RFID system does not require an internal battery; instead, it relies entirely on electromagnetic induction. When the smart ring is brought into close proximity with an active RFID reader or scanner, the reader emits a radio frequency field. The tiny antenna coil attached to the RFID chip inside the ring captures this radio wave energy, which momentarily powers up the integrated microchip. Once powered, the RFID chip transmits its unique stored identification data back to the reader via radio waves, authenticating the user or unlocking the connected access system. By housing this chip within a sleek, 3D-printed plastic ring customized to fit your finger using standard printing filament, the system transforms bulky access cards or key fobs into a seamless, wearable piece of smart jewelry. Using adhesive or glue, the extracted chip and its miniature antenna are securely sealed inside the 3D-printed housing, ensuring structural integrity and everyday durability for personal data security applications.
