Can you be hacked through 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.
Ultimately, NFC makes it a whole lot easier to perform a huge range of digitized tasks. But with that kind of power in such a tiny chip, is this technology really secure? Many experts say NFC really is fundamentally secure by virtue of its extremely short range. In order to snag your NFC signal, a hacker would need to be very close to you.
