Many customers ask the NFC of battery. Now, let's us help you to recognize what is NFC.
NFC is Near Field communication
Where is the location of NFC in your cell phone?
Such as, iphone the NFC is a NFC chip at the back of your cell phone cover.
Such as, Samsung cell phone have NFC inside of battery, when you tear the sticker of battery, you could find the NFC.
The problem with NFC is that it requires quite a large antenna, and lithium ion batteries tend to block the signal. So phone makers have two solutions: put the antenna on the back of the battery, or put the antenna on the back of the case.
This is why Samsung batteries that have this built-in antenna are marked "Near Field Communication" on the label:
And if you buy any after-market batteries for those phones, you have to make sure that they are "NFC capable", since after-market batteries without the NFC antenna stops the NFC functionality on your phone from working.
Apple's Apple Pay (which is NFC) actually mill their antenna into the back plate of the phone:
So, if you're worried about the chip stealing your data, you can feel free to peel it off. It'll stop your NFC functionality from working, but that's the price you have to pay when you follow misguided internet paranoia.
Oh, also you should probably never use wireless charging, because it uses a similar type of antenna that's fitted to the back shell on some phones.
You know, you should probably just remove ALL antennas just to be safe. It's the only way to absolutely ensure that nobody can possibly track your phone usage.
