Looks like the Chinese actually invented the smart ring 300 years ago
While tech geeks are excited for the newest piece of wearable technology in our digital age, it appears that we weren't the first to invent jewelry capable of computing. This abacus ring was used by Chinese traders during the Qing Dynasty nearly 300 years ago.
The Zhusuan ring is a 1.2cm long and 0.7cm wide abacus made up of seven rods with seven beads on each rod. The beads are too tiny to move with fingers, so it requires small tools, like pins, to function. Traders used the tool to make quick calculations. The origins of the ring are unknown, but it is speculated that it was designed for female traders who could use a hairpin to move the beads.
