What is RFID?


RFID stands for Radio Frequency Identification , which is a wireless communication technology that allows items like credit cards and passports to be scanned by machines within a short distance. This technology enables cashless payments and facilitates immigration management, but it has also raised some security concerns as some people may use RFID readers to steal your personal information and financial data.


What are the risks of RFID?


The risks of RFID primarily come from RFID attacks, which involve the use of illegal or concealed RFID readers to scan your credit cards or passports and obtain information such as your name, card number, expiration date, nationality, and date of birth. This information can be used for fraud, identity theft, and other criminal activities.


Is RFID blocking effective?


RFID blocking is a method to prevent RFID scanning, and some products claim to have this functionality, such as wallets and passport sleeves. The principle of RFID blocking is to use materials like carbon fiber or aluminum to shield RFID signals and prevent communication between RFID readers and RFID chips.


The effectiveness of RFID blocking depends on various factors like the power, frequency, distance, and angle of RFID readers. Generally, RFID blocking can reduce the likelihood of RFID attacks to some extent, but it cannot completely eliminate the risk. Some RFID readers may use more powerful or sensitive devices to overcome the blocking effect. Moreover, RFID blocking may also affect the scanning speed and accuracy when using credit cards or passports normally.


Do you need RFID blocking?


Whether you need RFID blocking depends on personal preferences and needs. If you feel that using RFID blocking can make you feel more secure and at ease, you can choose to purchase products that are of good quality, reasonably priced, and aesthetically pleasing. However, please remember that RFID blocking is not foolproof; it can only provide a basic layer of protection and cannot completely prevent all types and degrees of attacks.


The real threat lies in the internet, not RFID


In fact, the risk of RFID attacks is not very high as the RFID information on credit cards and passports is encrypted, and attackers need to be very close to the victim to conduct scanning. Moreover, even if attackers obtain your RFID information, they may not be able to use it for transactions or identity authentication, as they would still need to know your passwords, verification codes, fingerprints, and other verification methods.


On the other hand, the real threat lies in the internet. When you use a computer or mobile phone to browse websites, send emails, download files, make online purchases, etc., your privacy and data can be compromised by hackers and eavesdroppers. They may use methods like phishing, ransomware, malware, and man-in-the-middle attacks to steal your account information, passwords, bank card details, personal photos, contacts, and other sensitive information. This information can be used for more serious and wide-ranging criminal activities like extortion, blackmail, threats, and defamation.
