The TRIDENT system is a custom-engineered tip at the core of making Nuwa Pen work (which is why we patented it). It’s a cutting-edge combination of some of the world’s smallest camera sensors, a uniquely designed infrared guidance mechanism in a compact design, ensuring all the parts are protected. At the heart of the TRIDENT system is a slot for the ink cartridge to go through. It’s a brilliant piece of technology that enables us to break new ground in digital writing.
