NFC Transponder with UART interface

Silicon Craft Technology, having successfully marketed the NFC product worldwide, has recently introduced and launched the NFC Enabler (SIC4310), a dual-interface NFC tag that is compliant to ISO 14443A.

The SIC4310 is designed for use in various types of applications for home appliances and personal healthcare, sports and fitness devices, to name a few. The key challenges in developing this type of application were to deploy a low-cost NFC tag, instead of an expensive full functional reader IC, and to use smartphones as a hub of information. The resulting concept will enable a tremendous number of NFC applications on smartphones. For instance, by embedding the SIC4310 tag into a treadmill, the user can touch his or her smartphone and transfer personalized information to a given device (e.g. the user’s preferred speed and incline to an exercise machine). Moreover, the user’s statistics can be saved and visualized on a smartphone through NFC.

The SIC4310 samples are ready to distribute, along with Software Development Kits for Android, ARM Cortex M0, Arduino, and Windows platforms.
