What is NFC phone?

Near Field Communication (NFC) allows the transfer of data between devices that are a few centimeters apart, typically back-to-back. NFC must be turned on for NFC-based apps (e.g., Android Beam) to function correctly.

How does near field communication work?

Near-field communication transmits data through electromagnetic radio fields to enable two devices to communicate with each other. To work, both devices must contain NFC chips, as transactions take place within a very short distance. With near-field communication, you must perform an action intentionally.

What can NFC do?

Put an NFC tag near your door and set it to do things like: enable Wi-Fi, decrease brightness, disable Bluetooth, and auto-sync.

Can NFC be hacked?

NFC is a useful technology for certain functions. But it’s not without its security risks. Because it lacks password protection, it’s possible for hackers to access NFC data. They can even do this without you being aware of it.

Is Near Field Communication safe?

So it’s good to be aware of potential security risks with NFC. All things considered, NFC-enabled card payments are more secure than traditional swiped transactions. And with payment security solutions like encryption and tokenization, there’s a reduced risk of theft of the physical card and actual card numbers.

How far can NFC?
