NFC technology: If not used carefully, your account will be emptied, know safety tips
In the growing scope of technology, NFC (Near Field Communication) is becoming increasingly popular. NFC is being used in today’s smartphones, credit cards and other digital devices. But along with the benefits of this technology, there are some risks associated with it, from which it is important to be cautious. In this news, we are going to tell you what is NFC, how it works and what things should be kept in mind while using it.
What is NFC and how does it work?
NFC is a wireless communication technology that allows two devices to transfer data at a distance of just a few centimeters without any physical contact. This technology works on the principle of Radio Frequency Identification (RFID). NFC devices just have to be brought close to each other and they connect automatically. Its speed and security make it very useful.
