NFC Security Risks and Solutions – Be Vigilant While Making Transactions 

Have you ever wondered how you pay your bills at a store by scanning your card against a machine? That’s because of NFC technology.  94% of our mobiles are NFC enabled, but what’s NFC?.

NFC is a near field communication that enables your devices to communicate over short distances. This particular technology is not just limited to payment methods. Modern-era train tickets and even door locking systems use this technology. Let’s see how it works. 

How Does NFC Technology Work?

NFC works on radio technology. It sends small radio signals to the other device. This distance is normally ten centimeters but can vary from device to device. For instance, in most cases, you don’t need to contact your mobile with the card reader. The radius is enough for the signals to travel between two devices. 

This technology allows and enables you to carry out contactless transactions. Through NFC, you can share digital content or connect devices with a simple touch. It is a system with a speed limit of 424 kbit/s, so it is designed to quickly and easily exchange little information.

Potential usage of NFC in various sectors

NFC is solving a major and big pain point and that is providing secure contactless payment systems for mobile payment processing. But that is not all because this technology is going beyond mobile payments. Let’s look at how this technology can grow in various industries.

Transportation and Manufacturing

NFC is ideal for contactless ticketing systems and fleet management. The tech makes it convenient for commuters to access buses, trains, and subways without ticket hassles.

Also, NFC tags can be used to track and manage vehicles in the logistics and transportation industries. 

The manufacturing industry can also achieve quality control and machine maintenance with the help of this technology. For instance, NFC tags can be attached to products for quality control and tracking purposes. 

You can use them for records and tracking equipment status, which will help to reduce downtime.

NFC in escape rooms and employee control system 

NFC technology can be implemented in escape rooms because it effectively activates automation. For instance, an NFC tag can be placed in a certain location, so when anyone taps on it, it triggers a mechanism that opens a door.

Also, NFC technology can be used in employee control systems to track security personnel’s movements easily. 

NFC in healthcare

NFC technology can be surprisingly beneficial for healthcare. NFC tags can provide medical professionals crucial information about a patient’s treatment plan. The tech can also track interactions with doctors and nurses. 

NFC tech in healthcare works this way. Every time patients visit a healthcare facility, their NFC tag is scanned to collect clinical and laboratory data. This is then securely stored in real time on a server.

Inventory management

NFC technology can be used effectively in inventory management. For instance, by placing an NFC tag on an object, you can see its location and more related information.

In these labels, there can be product information, including batch number, ID, and other documentation. Making use of NFC technology means ease for the logistics and transport sector.

We all know that inventory management is a slow process, but implementing NFC technology can make everything easy, fast, and reliable.

Security in Workplaces

One of the admirable advantages of using NFC technology in companies is improving security and control of protocols. 

With the use of NFC tech, you can monitor work teams. Also, NFC can be used to create secure access control systems. Employees can be issued NFC cards or badges, which they must tap or scan at specific entry points to access restricted areas.

At the same time, NFC can be used for time tracking and attendance monitoring. For instance, employees can use NFC-enabled devices to clock in and out of work. This helps companies accurately track employee working hours.

What are the Perks of NFC – is it worth the hype? 

The advancement in technology always happens to make things easy for people. Near Field Communication is no such exception. There are numerous perks of using NFC that you cannot ignore. Let’s have a look at them.

Convenience

The first and foremost perk of using it is that you don’t have to carry a wallet full of cash everywhere you go. All you need is your NFC enabled device, and you’ll be ready. The easy data exchange between devices allows people to save time without waiting for the cashier to return the change. 

Compatibility

Another remarkable thing about NFC is that it’s compatible with various devices and can be used for multiple purposes. 

From mobile payments to data transfer, from ticketing to access control, there are many ways it can be used at your convenience. 

Environmental sustainability

We know how much damage climate change has caused to our planet. Using NFC enabled devices can play an important and vital role in environmental sustainability. Using it will end the continuous usage of printed materials, physical cards, and even tickets. 

You’ll be saving a lot of trees, and that’ll bring peace and warmth to your planet. 

What Are the Shortcomings of NFC Technology? 

Although there are numerous perks of using NFC, there are also some shortcomings. 

Limited data transfer

One of the problems that people have faced while using NFC is the limited data transfer speed. 

It means that when it comes to large transactions that involve high transfer speed, you won’t be able to do it. 

Short range 

Another drawback of using the NFC system is that it only works within a short range. This makes it less reliable than other data transfer technologies like Bluetooth. 

Device compatibility issues 

Not all devices support NFC, particularly if they are outdated. It’s important to note that devices involved in an NFC transaction, like smartphones and payment terminals, must have NFC capabilities to work.

Security concerns

It is stupid to think that NFC is immune to security threats. While NFC is considered secure for many applications, it’s not immune to security threats. 

If proper security measures aren’t in place, skimming, eavesdropping, and data interception are possible risks. The good news is that these risks are generally lower because of NFC’s short range.

Interference issues 

One other issue with this technology is interference. For instance, NFC signals can be disrupted by metallic objects and electromagnetic interference. This can affect the reliability of NFC communication in certain environments.

Security risks associated with NFC – All you need to know 

In majority of the cases, NFC technology is completely safe and secure. However, no matter how perfect it is, man-made things are bound to have some errors and NFC is no exception. There are some security risks associated with NFC that you should be aware of. 

Eavesdropping 

Eavesdropping is a bad habit of listening to other people’s conversations secretly and in the case of NFC, it means accessing the data of a user without their consent. In this type of security risk, a hacker may use his app within the range of near field to steal your data. 

Almost 37% of people have suffered from eavesdropping so far. Although it’s not common yet it’s possible. 

The hacker really needs to be quite close to the card reader and he won’t go unnoticed if you’re in your senses. But precautions are really needed.

Phone malware

In the year 2019, a shortcoming or a loophole was detected in Android devices that allowed the hackers to use NFC to prompt the device to download an application. If you’re an Android user, you’ll know that it’s only possible to download apps on the mobile from Google Play. 

If you try to do it from another site, there’s always a strict warning that comes with it. However, this prompt didn’t give any warning. The bug or NFC vulnerability in the devices was later on eradicated however, it opened people’s eyes to the security factor linked with using NFC. 

Hackers can use NFC technology to use it for malicious intent.

Relay attack 

As the name suggests, the relay attack happens when a device is near the NFC transaction device. This device picks up your data and doesn’t do anything malicious to it. 

It passes this data to the third device, and in most cases, it is used for malicious purposes. This attack can also be avoided if you stay alert when making an NFC transaction. 

Skimming

It’s another form of security risk that you shouldn’t take lightly. In these situations, the attacker may carry a handheld card reader and pass you by so closely that it initiates a transaction through your phone. 

However, for this to happen, the hacker will have to come quite close to your device and know the exact location of where you’re keeping it, yet it’s risky enough if you don’t take proper measures.

Replay attack 

In the context of NFC, a replay attack involves intercepting and storing NFC communication between devices. However, instead of immediately using the intercepted NFC data, the attacker saves it for later use. 

When the attacker replays this data, it can result in unauthorized transactions or actions. This leads to financial losses or security breaches.

Incorrect amounts risk

The hacker doesn’t usually do this. It’s often a mistake the person handling the NFC transaction process commits. They may enter the wrong amount on the card reader, and if you don’t read it carefully, you may end up paying more money than required. 

However, this happens on NFC enabled apps that don’t show you the amount while making transactions.

Cloning

As the title suggests, a hacker or attacker can create a duplicate version of an NFC device with the same NFC profile as the original one. 

Cloning of NFC keys is a relatively easy nut to crack for hackers. They may create a clone of someone’s key and then use it to unlock the data that the real owner was trying to protect.

How do you protect yourself against NFC risks?

Although in most cases, the hackers need to be close to the NFC enabled devices, that’s not the only way. Hackers have learned updated ways of attacks; to avoid them, you need to be extra careful. Here is what you can do.

Turn off NFC when not in use

To mitigate security risks associated with NFC, it is advisable to disable it when it is not actively in use. This precautionary measure restricts unauthorized access via NFC. It will help you safeguard sensitive data and ensure that NFC transactions occur only when explicitly intended.

Enable authentication 

One of the most effective ways of protecting your devices against NFC security risks is by enabling two-step verification for NFC keys. This way, you can create an extra layer of protection and keep your data safe and sound. 

You also need to do the same with credit or debit cards. The hacker won’t be able to steal anything even if he gets his hands on your NFC key, as it’ll be protected by fingerprint or password, and the same is the case with cards. 

Updates are a must

In order to keep your NFC transactions safe, you need to keep your NFC infrastructure up-to-date. It’s because outdated hardware or software are NFC’s most common security vulnerabilities. 

Choose trusted applications

When dealing with NFC technology, it’s wise to pick and trust apps you’re familiar with. Always stick to well-known options that have a good reputation for security. 

If you’re downloading new apps that want access to NFC, take a moment to check their credibility. This simple step goes a long way in protecting your NFC activities and your data.

Watch out for new apps

Exercise caution if you encounter apps you haven’t used before, and they request NFC access. It’s similar to being cautious when meeting someone new; you want to learn more about them before trusting them completely. Doing so reduces the risk of potential security issues related to NFC usage.

Monitor your device 

When you have your device with NFC capabilities near others, it’s a good idea to keep an eye on it. NFC works when devices are very close together, so it’s essential to know who’s nearby. 

Keeping an eye on your device helps prevent any unwanted NFC interactions. This simple act of vigilance can help safeguard your information.

Use RFID-blocking wallets or sleeves

Do you know your credit or debit cards have a tiny chip that can communicate with machines when you wave them close? 

This chip uses RFID technology. Some people with malicious intent might scan your card without your knowledge and potentially steal information.

You can use special wallets or sleeves to protect your cards from such scans. Sleeves, for instance, have a special material that prevents the chip from sending signals when you don’t want it to.
