<h2>Introduction to RFID Technology and Its Vulnerabilities</h2>

Radio Frequency Identification (RFID) technology has revolutionized the way we interact with everyday items, from contactless payment cards and passports to key fobs and inventory tags. RFID systems use electromagnetic fields to automatically identify and track tags attached to objects. These tags contain electronically stored information that can be read from several meters away without direct line-of-sight. While this convenience has streamlined many processes, it has also introduced significant security risks. Unauthorized individuals with RFID readers can potentially skim or clone data from these tags without physical contact, leading to identity theft, financial fraud, and privacy breaches. This is where RFID blocking sleeves come into play as a simple yet effective countermeasure.


<h3>How RFID Blocking Sleeves Work</h3>
RFID blocking sleeves are protective enclosures made from materials that interfere with electromagnetic signals, effectively creating a Faraday cage around your RFID-enabled devices. The primary material used is often a thin layer of metal, such as aluminum or copper, woven into fabric or embedded in plastic. When an RFID card or passport is placed inside the sleeve, the metallic layer blocks radio waves from reaching the tag, preventing unauthorized scanning. This works because the conductive material absorbs and reflects the electromagnetic energy, ensuring that signals cannot pass through. It's a passive form of protection, meaning it requires no power or user intervention—simply sliding your card into the sleeve activates the shielding. This technology is highly reliable and has been tested to block frequencies commonly used in RFID systems, including 125 kHz (low frequency) and 13.56 MHz (high frequency), which are standard for credit cards and passports.
