NFC Ring
A RING THAT CAN UNLOCK YOUR ANDROID PHONE.
What is NFC?
NFC or near field communication is a short-range high-frequency wireless communication technology. NFC is mainly aimed for mobile or handheld devices. NFC is an extension of radio frequency identification or RFID technology. RFID is mainly used for tracking and identification by sending radio waves. NFC works using magnetic induction between two loop antennas located within each others 'near field'.
Purpose: The purpose of my project is to create and innovative device that can be used easily to perform a task that usually takes more time. It is perfect because it quickly unlocks your phone without inserting your code. It is safe and only you can do it!
DRIVING QUESTION: How can a ring unlock a phone with no touch?
Hypothesis:
The thing that will make this project work is the NFC tag, First measure finger in order to find the one that fits well. The ring will have a tag in the top and will unlock an android phone quickly because it has a high-frequency wireless communication technology. It is important to install a series of programs in the device in order to record the code information of the phone in the ring.
Materials:
3-D Printer
13.56MHz RFID/NFC Bracelet - KB
Android Phone with NFC function
Procedure:
*Design and 3-D print a ring.
*Get a little circle out of the NFC bracelet and glue it to your ring.
1. Make sure that the NFC function is on.
2. Go to settings-lock screen, and pick a pin that will lock your phone.
3. Then, tap on Smart Lock.
4. Select Trusted Devices and then NFC.
5. Set up everything by touching the back of the phone with the NFC Ring.
6. Now try it! You can easily unlock your phone now.
Safety:
The instructions of the Mod Android Installation will wipe all your personal data from your device and there is the potential to cause permanent damage to your phone, make sure to have a backup of photos, data, and important information.
Variable set:
When choosing Secure Settings, click on Dev Admin Actions then Password/Pin. Check the box next to Device Admin Enabled and enter a password to unlock phone.Tap the save icon at the top of the screen. Tap the Tasker logo to go back to the Task Edit screen. Add two more actions: the first is very similar to above, but in Secure Settings select Actions-Keyguard-Off.
The third action sets a user-defined variable in Tasker, named NeedsLock, to 1.
Analysis:
The global near field communication (NFC) market size was valued at USD 4.80 billion in 2015. The growing mobile penetration with improved payment infrastructure and data connectivity presents a significant opportunity for the growth of NFC-enabled mobile payment.
Growing popularity of mobile devices and the increasing number of online consumers is expected to drive the demand for m-commerce.
Conclusion:
NFC works using magnetic induction between two loop antennas located within each others 'near field'. It's an innovative function that will soon be part of our lives. Is very easy to use and it helps you do various tasks at once by just sliding your tag under the phone.
Application and Further Research:
The NFC functions are developing more and more every day. I want to be able to install an NFC function to any phone. Since I used many tags for my project, I was able to do research and learn more about this fantastic task! I think it can improve by putting all of our everyday tasks in just one single tag in a thing that we always use, like a ring.
What is the application of your project in daily life/economy?
My project can help the customers to find and innovative way to operate various tasks in your phone.
What would be the next question to ask?
How can someone install the NFC function to an older version of an android or just any phone?
If you repeated this project, what would you change?
I could repeat again this project, I'll have worked even more hard to create different original styles and play with different ways to use the amazing NFC tag.
