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.
