What is an RFID Blocker and How Best To Use It For More Security

RFID technology, just like any other technology, might have a few security challenges. That is why as a user, you need to know the best security practices if you are ever going to keep using the technology effectively. Because of such, you would need an RFID blocker to help improve the security of the RFID technology.

So, what Is an RFID Blocker?

An RFID blocker is a material or device built to prevent or limit the scanning and reading of RFID tags, cards, key fobs, and other types. Right now, RFID is an important technology in various fields. There are some tags that open important and secretive doors. It just shows how important this technology is to users. Being able to scan them means you can easily end up with unauthorized access to sensitive information or space.

The main reason someone would start using RFID blockers is to ensure there is better privacy and security to avoid someone reading and cloning vital information stored on RFID tags. So, if you have implemented RFID technology as part of your security system, it is time to invest in an RFID blocker to enhance security even further.

 

Privacy Issues Associated With RFID Technology

Privacy Issues Associated With RFID Technology

People invest a lot in RFID blocker material because they understand the importance of maintaining privacy. You would not want to end up damaging your reputation when you can maintain privacy with an RFID blocker. Below are some of the privacy issues commonly associated with RFID technology.

  1. Tracking and surveillance can be a big deal, especially when someone has access to important areas, and the access involves using RFID cards. That means the company’s secrets might be exposed, and the person would be followed everywhere because of their RFID card.
  2. You may also have issues with unauthorized data access. Most people might not realize that RFID technology can contain sensitive information such as your financial data. When someone accesses such data, it becomes a big deal and can leave you with more privacy issues.
  3. Data aggregation is a real problem, especially for those with a lot of information stored on their RFID devices. A good example is that you can know more about a person just from reading the patterns of how the RFID card is used. Let us say someone has linked the card with their banking details, you can easily get the banking information and spending habits of such a person from the RFID card.
  4. Not all RFID systems are built equally. Some might have inadequate security measures. When there is a lack of robust security features, you end up with systems susceptible to hacking and cloning. Criminals are likely to exploit such vulnerabilities, thus compromising the overall privacy of the system.
  5. Cloning and spoofing are nothing new, but you must be aware of them. They can also be extended to the RFID technology. This is where the RFID tags are spoofed or cloned by people with malicious intent. The result is some people will now have access to your office, home, or any other secure areas you are trying to protect.

Common Types of RFID Blockers

Common Types of RFID Blockers

Now that you know more about the potential issues with unauthorized RFID scanning, you would then want to find a solution to such a problem. That is when you have to think of the common types of RFID blockers. We look at several options below.

RFID Blocking Wallets

These RFID-blocking wallets are built with RFID-blocking materials as part of their design. You can get some having metal layers and special fabrics designed to prevent RFID scanning.

The wallets use these RFID-blocking materials to act as a shield, preventing the RFID signals from easily penetrating the wallet. The result is that you now protect the cards inside the wallet better.

Electronic RFID Blocker

This can be a good RFID Blocker for keys or cards that you own. These are active RFID blockers since they have electronic jamming crucial for effectively disrupting the RFID signals.

These devices emit radio frequency interference, making it hard for the readers nearby to get the data from RFID tags.

Such devices can effectively protect the information on your RFID tags, but they need a constant power supply, such as using batteries.

RFID Blocker Card

You can also get cards designed to work as RFID blockers. They are similar in shape to the RFID cards to look like a disguise, but they do a lot more. Because of their size, using them alongside your regular cards becomes easy while they perform the extra security function.

Being slim makes them easy to use with other wallet setups. This becomes an easy-to-use product for most people.

RFID Blocker Sleeve

A sleeve and a wallet are totally different things. Generally, sleeves are slimmer but can still be made of materials that can block RFID signals. They work similarly to wallets and can easily interfere with the RFID signals to prevent any authorized scanning. Most people find such sleeves convenient to use even with cards.

DIY RFID Blockers

Making an RFID blocker from some materials around you is still possible. You can find some good options for blocking RFID signals depending on your skill level.

Many people use aluminum foils to act as shields for RFID signals. You just need an aluminum foil with an adhesive and a pair of scissors. Cut the foil to shape and put the tag inside. The metal nature of aluminum makes it hard for the readers to pick the signal.

If you can get the RFID-blocking material or fabric, you can make a wallet out of it. Do the same as you did for the RFID wallet above, and you should be good.

If you ever find such solutions hard to achieve, consider getting the ready-made options already mentioned above to effectively protect your RFID tags.

 

Considerations For Choosing RFID Blockers

Considerations For Choosing RFID Blockers

Since we know the importance of RFID blockers, it is best if we also know how to choose the right ones for our needs. Here are some considerations you can make to pick the best RFID blockers.

Material Quality

You must understand the type of material used to make the RFID blockers. The last thing you need is to use materials that do not work effectively. So, start by evaluating the material’s ability to block the RFID signals and also choose based on the materials’ durability.

Design and Functionality

The overall design and form of the RFID blocker can influence whether you get it or not. Common options are wallets, cards, sleeves, or fabric.

Choose the right design depending on your personal preferences, lifestyle, and routine. This means the design and functionality should allow for quick access and convenient use of your RFID tags when necessary.

Size

The size matters since you need the RFID blocker to accommodate your RFID devices. Let us say you have RFID cards, then consider a wallet big enough to hold the cards without a problem. Also, the RFID blocker should be versatile to work with other items you own, such as key fobs, credit cards, and more.

Cost

It is expected that some of the RFID blockers will be more expensive than others. Since these blockers vary in price, make sure you only choose those within your budget that still work great to block RFID signals. That is where value for money comes in to ensure you balance between the features of the RFID blocker and its effectiveness at doing its job.

Reviews and Ratings

If you buy the RFID blocker from a store with reviews and ratings, they can be a great way to understand how well they work. Make sure to consider buying products with more positive reviews. These reviews help you understand if the product provides the RFID blocking performance.

Pay attention to any recurring issues that might be mentioned by other users in their reviews.

Conclusion

Using RFID blockers now stands out as an important option you should get. The last thing anyone needs is to end up with security breaches when they could all have been avoided. We recommend taking the time to seek the best way to block RFID whenever necessary as an added security layer to existing options. Also, do not forget to research more on a product before deciding to settle for it.
