If you've ever heard the term "HotKnot" on a smartphone or tablet, you might wonder what it's all about and what you can do with it. That's exactly what we want to talk about here. Hot Knot is a transmission technique and is very similar to the "NFC" method.
This means that HotKnot can transfer data over a very short distance. This does not make the technology different from NFC. The technology at HotKnot is completely different from Near Field Communication. Because here instead of an antenna simply the capacitive display of the smartphone is used.
Because here instead of an antenna simply the capacitive display of the smartphone is used. In other words, if you want to pair two devices or exchange data, you can simply stick the smartphone displays together and then exchange data via HotKnot or pair devices. Advantages with HotKnot compared to NFC is:
- Cheaper to implement for the manufacturer
- Battery consumption should be lower
Whether HotKnot will prevail over NFC in the future remains to be seen. In any case, the technology is a fine thing and will probably soon be implemented by more and more smartphone manufacturers.
