There is a high market sizing of readers, tags, and software designed for RFID cards. With advances in technology, this security industry has experienced a major overhaul. Door security, for example, has evolved from simple padlocks and keys to RFID-enabled cards that can be swiped or waved to open doors. During the pandemic, the demand for RFID contactless cards has been greater as people were looking for ways to minimize contact with surfaces. However, concerns for security are always on the table, with any new technology. While this technology is amazing and has many benefits to its users, it requires constant adaptation and evolution to defend against malicious users. The following are some of the reasons why RFID cards cannot be copied.
The cards use a one time code
RFID cards use one-time codes to complete each transaction, unlike traditional credit cards. These cards are considered to be very safe because of how they transmit information. Data theft concerning RFID cards is uncommon because the cards use one-time codes to complete each transaction. RFID copying is also difficult because every time you use your RFID card, a new code is created, therefore, your information cannot be compromised.
Each chip in the card has a unique identifier
Each RFID tag has to be unique to uniquely identify an item. The tag has unique EPC numbers so that they can be differentiated from one another. On RFID cards, the EPC number is integrated into the tag’s chip.
When each RFID chip is manufactured, it is encoded with a unique identifier number that cannot be changed. The chip inside the RFID card has a unique identification number that includes a unique serial number for that tag and the traditional information contained in a printed barcode (indicating the product type and manufacturer). Therefore, each card will be uniquely identified and cannot be copied to have two cards with the same serial number.
RFID cards are highly encrypted
RFID cards contain encrypted texts that are done to prove that data on RFID is safe and cannot be easily read or copied. The encryption scheme used makes it impossible for them to be copied into cloned cards. Most of these cards are encrypted using the WAKE (Word Auto Key Encryption) algorithm. The algorithm uses cryptography, a study of mathematical techniques related to aspects of information security such as data authentication, data integrity, confidentiality, sender/recipient authentication so that documents or messages are secure and unreadable by unauthorized parties. The general purpose of cryptography is authentication, access control, integrity, and nonrepudiation.
RFID chips are highly secure
Security is the top priority for RFID chips. Manufacturers have made chips differently with each card running on a different frequency to avoid an RFID chip from being copied. Even though the cards look the same, they cannot be copied once the original card has been encoded.
Conclusion
Even though RFID cards are the most secure cards at our disposal, it is still important to take precautions as you would with any other card. Consider using an RFID blocking sleeve or wallet to offer protection against RFID skimming.
