Near field Communication (NFC) is a technology similar to Wi-Fi and Bluetooth Low Energy (BLE). At the same time, it’s a powerful enabler. The nature of proximity connectivity realizes the potential of an Internet of Things (IoT). Khushi Baby is one example of the impact such products can make on the world.
Traditionally, haala khaago black thread is worn by Indian children for protecting them from the evil eye. The Khushi baby (KB) necklace is designed based on this tradition. However, the KB is also embedded with an NFC chip that can be scanned by health care providers with a mobile app in a cell phone to obtain the wearer’s immunization record. What is the significance of this technological addition that costs less than a dollar?
Over 1.5 million children die from vaccine-preventable disease each year. In under-developed countries, especially in isolated rural areas, a major barrier to healthcare and immunization provision is tracking health records. With KB, a child’s data is synced to a cloud database and can be transformed into insights to be acted upon. Currently, thousands of children are benefitting from simple and inexpensive this innovation.
Another example of NFC in action is the adoption by chip makers. Texas Instruments (TI) is marketing a new NFC-enabled transponder targeted at automotive infotainment apps. The RF430CL330H-Q1 is an NFC Tag Type 4 device that combines a wireless NFC interface and a wired SPI or I2C interface to connect the device to a host. With a tap, the NFC interface enables end equipment to communicate with the infrastructure of NFC-enabled smart phones, tablets, and notebooks. It’s a path to IoT.
NFC will continue to serve as a powerful contributor to the IoT world. Vision and innovation will be the main driving force. From rural healthcare to transportation and more, continued creativity and development will unlock worlds of potential for the future.
