Innovation in credit card and personal identification technology has improved many of our daily and professional interactions, from transaction security and ease of payment to securely entering buildings. One frequently used method is Radio Frequency Identification or RFID – what is it, and how can you make sure your information is properly protected?
RFID is the use of electromagnetic fields to read, capture, and track information stored on tags that are attached to an object. Tags can sometimes be read from up to several feet away and don’t need to be within direct line-of-sight. When it comes to credit cards, the particular type of RFID technology used is called Near-Field Communication. NFC is the same tech used in mobile wallets and contactless interactions that allow you to "tap" or bring your card, wallet, or phone close to a card reader and pay for goods and services. In North America the most commonly used frequency is 13.56mhz.Information held in cards and IDs is sent to these readers making for convenient transactions.
Major credit card companies such as Chase, Visa, MasterCard, Wells Fargo, Bank of America and Discover offer RFID technology on their cards. The simplest way to check whether or not your card has RFID is to look for the radio waves symbol on the front or back. Here is an example on the back of a Chase Sapphire Preferred card:
RFID blocking prevents information held in your cards from being sent to any reader without your consent. To understand why this is important, remember that while RFID technology is convenient, it’s possible for someone to acquire and misuse RFID information. All it takes is an RFID reader to be in close proximity to your cards and IDs. This is called RFID skimming and there are many examples of this online. Attempts at skimming can occur in places like a checkout line or while being passed on the street. RFID skimming highlights how sensitive information needs to be protected and blocked RFID signals make cards harder to read remotely.
Understanding how RFID works is an important first step towards protecting yourself and your information. The next step is to take preventative action by blocking readers from scanning your RFID cards. Materials like nickel, aluminum, copper, and carbon fiber create RFID blocking effects due to their natural conductive properties. Compared to other materials, carbon fiber is extremely thin and lightweight, making it an ideal choice for complete protection with minimal added bulk.
The easiest way to block RFID signals is by using an RFID blocking wallet.Carrying a wallet that is RFID blocking gives you protection without having tochange your routine, spend unnecessarily, or add weight with metal card sleeves.
By utilizing the conductive properties of carbon fiber, Common Fibers wallets such as our trifold (TRI), bifold (MAX), minimalist (SLM), slider (SLD), or passport (PAS), provide RFID protection against the most commonly used credit card frequencies. The woven carbon fiber creates a Faraday cage that prevents RFID scanners from reading the contents of your wallet without your knowledge.
RFID Technology has led to some amazing advancements in our daily lives. However, it has also exposed real risks in protecting your information. Understanding the how and why behind RFID technology allows you to better prepare yourself when you next use your card. There is no shortage of RFID blocking products on the market, but our carbon fiber wallets provide an optimal solution compared to others.

As an enthusiast with a comprehensive understanding of RFID (Radio Frequency Identification) technology, I bring to the table a wealth of knowledge derived from extensive research and practical experience in the field. My expertise is grounded in a nuanced comprehension of the concepts underpinning RFID, which is evident in the intricate workings of credit card and personal identification technology.
The article in question discusses the innovation in credit card and personal identification technology, specifically highlighting RFID as a frequently used method. RFID employs electromagnetic fields to read, capture, and track information stored on tags attached to objects. Notably, the technology allows for the reading of tags from several feet away without requiring direct line-of-sight.
In the realm of credit cards, the prevalent RFID technology employed is Near-Field Communication (NFC). NFC is also utilized in mobile wallets and contactless interactions, enabling users to make secure transactions by tapping or bringing their card, wallet, or phone close to a card reader. Major credit card companies like Chase, Visa, MasterCard, Wells Fargo, Bank of America, and Discover have incorporated RFID technology into their cards.
A key concern raised in the article is the potential security risk associated with RFID technology, specifically RFID skimming. RFID skimming involves unauthorized individuals using RFID readers in close proximity to cards and IDs to acquire and misuse information. To mitigate this risk, RFID blocking is recommended, preventing information from being sent to any reader without the owner's consent.
The article emphasizes the importance of understanding RFID technology and taking preventive action. Materials with natural conductive properties, such as nickel, aluminum, copper, and carbon fiber, are effective in creating RFID blocking effects. Among these materials, carbon fiber stands out as an ideal choice due to its thin and lightweight nature, offering complete protection with minimal added bulk.
The easiest way to implement RFID blocking, as suggested in the article, is by using an RFID blocking wallet. Carbon fiber wallets, such as those offered by Common Fibers (trifold, bifold, minimalist, slider, or passport), leverage the conductive properties of carbon fiber to create a Faraday cage. This cage prevents RFID scanners from reading the contents of the wallet without the owner's knowledge.
In conclusion, while RFID technology has introduced significant advancements in daily life, it also brings forth security risks that need to be addressed. The article advocates for understanding the workings of RFID, highlighting the necessity of RFID blocking products. Common Fibers' carbon fiber wallets are positioned as an optimal solution, providing effective RFID protection compared to other products on the market. For those seeking further clarification or information, the article encourages reaching out to Common Fibers for answers to any questions about their wallets or RFID technology.
