What is it and should you be excited?
Hot Knot has been around for a quite a while and was actually developed in 2013 by a Chinese touchscreen designer Goodix.
The technology allows the capacitive touchscreens of smartphones to interact – a feature that can be used for quick data transfer/sharing, in a similar way to NFC.
When the two screens are near each other, their physics are used in such a way that allows one of them to act as a transmitter and the other one as a receiver.
In order for the technology to work, the two phones need to come with Hot Knot technology and be in close proximity to each other (within at least one centimeter).
Then a connection between the two phones will be established and the devices will be ready to communicate and share.
What will you be able to do with Hot Knot Technology?
Hot Knot allows you to perform most of the same actions that you would have with NFC, such as:
Transfer and exchange photos and videos
Sharing contact data: web addresses, phone contacts, social media contacts, etc.
Sharing application data
Facilitate mobile payments
Exchange game moves
Enable Bluetooth pairing, Wi-Fi connectivity and other services.
How To Enable Hot Knot On My Phone? Can I download an App?
To enable Hot Knot on your smartphone, go to Settings>Hot Knot. A question will appear on the screen “Allow data exchange when the screen touches another device?”. Once you toggle it on, Hot Knot will be enabled and once you have your phone’s screen close to another device’s screen, you will be able to perform data exchange.
For those of you wondering if you can download Hot Knot through an app, the simple answer is no. There is no such thing as a Hot Knot app, because it’s part of the hardware of the phone.
How Does Hot Knot Compare to Bluetooth and NFC?
One of the major benefits of Hot Knot, compared to NFC, is cost-effectiveness. While NFC requires antennas and RF communication chips to enable data transfer, Hot Knot does the same without the above-mentioned additions and uses a new type of capacitor for touchscreens to make data transfer possible. At the same time, the speed of data transfer through Hot Know may be a bit slower than when using NFC, as the technology currently allows the transfer speed of about 7kbps.
Compared to Bluetooth, organizing data exchange via Hot Knot is an easier task, as you won’t have to search through the list of devices available for pairing, because the phones will have to be in a really close proximity to each other. for a more details look at Hot Knot and NFC check out this comparison blog.
