Is NFC still vulnerable to hacks? Not completely, especially since there are ways to mitigate the risk and make NFC a safe and secure technology. Businesses and even DIYers can mitigate the risks of using NFC in different ways. Using NFC may introduce risks, but it doesn’t mean that people should avoid it entirely. Hackers must find certain machines with security flaws to execute the hack and steal money. ATM Hacksīecause some ATMs have begun using NFC technology for contactless payments, hackers have also developed ways to hack the machines by waving their smartphones to the reader to get them to disperse money. Data corruption is a perfect way to lose data.īad actors will usually tamper with the exchange to authorise questionable transactions, like paying higher than the amount shown on the reader’s screen.
When a bad actor’s card reader or any other unauthorised reader reads an NFC tag, there is a possibility for the data exchange to be tampered with and for the data to be corrupted. NFC is widely used to exchange data, but there is a risk of the data itself getting corrupted. While this may make the data exchange seem secure, a man-in-the-middle attack can still occur through RFID skimming. NFC is naturally a short-range technology, meaning that data exchange can only happen when the NFC tag and the reader are close to each other.

Using NFC cards can also be risky when hackers set up their own NFC readers on machines to skin NFC credit or debit cards. NFC payments do not have this validation step, so thieves can easily use a stolen card without any worries.

Paying using a credit card usually requires cardholders to provide a user signature or a PIN code to verify the cardholder’s identity. Because the tag is so small, it’s easy not to notice them once planted in a bag. Bad actors can plant an NFC tag, like an Apple AirTag, to track someone’s movements. The risks with NFC technology aren’t limited to hackers stealing information from an NFC tag or infecting an NFC-enabled smartphone using their own tags. Below are some of the risks people can encounter when using NFC in any capacity. Hackers can compromise an NFC and NFC device’s security and tamper with data or steal information. Using NFC can have certain risks for businesses, especially those that deal with sensitive information. NFC is a secure technology, but it has some risks. Any bad actor who wants to hack an NFC device or infect it with malware must get uncomfortably close to the victim or look for other ways to attack.
The data exchange can only occur at a distance of roughly four cms. How Vulnerable is NFC Technology?įor a technology that’s fairly vulnerable to hacks, it is a somewhat secure platform for transactions and access control.

It has vulnerabilities, and it’s essential first to understand the vulnerabilities to know how to mitigate the risks. NFC is a widely used technology, and it’s no surprise that hackers find ways to exploit the technology. Currently, NFC tags are used to allow and restrict access to rooms and devices, to transact, and store information. It does not store any personal data.Near Field Communication or NFC is a convenient technology used to exchange data between two devices.
