Near Field Communication, also known as NFC is nowadays built into mostly every Android smartphone. NFC is not found in Apple’s iPhone, may be the company don’t want to integrate NFC to its flagship phone at this stage. NFC cannot only be used for mobile payments but it has got variety of other uses also, such as NFC tags can be used to turn ON WiFi, and do a lot other tasks.
However, NFC also scares a lot of users because of security concerns associated with it. For example, if your phone is stolen, then the thief could use your phone to make a purchase. Some security experts has pointed out various other concerns also and therefore if you are not going to use NFC, then it’s a good idea to turn it OFF.
Apart from security concerns, NFC can also be using some of your battery juice. It can be easily turned OFF from the Android smartphone. If you use this feature on a regular basis, then you may want to turn it ON and OFF every time, but if you don’t regularly use it, then you can just keep it disabled, which will save some of your battery life.
To disable it, find the “Settings” option and tap on it. From the settings, tap on “More” option and from here you can find the option to turn ON/OFF NFC. Simply remove the check-mark to turn OFF Near Field Communication. These steps may slightly vary depending on the version of the Android operating system that you are running. On some devices, Near Field Communication is enabled by default and therefore you should disable it.
I don’t, in any sense mean, that NFC should not be used. If you rarely use NFC, then it’s a good idea to turn it OFF. Since NFC is very short range technology and if you don’t lose your phone, then there are not much security concerns left with it. But NFC has a real effect on battery life. You will need to test out how much battery life you gain by turning it OFF.
