What is RFID?
The full meaning of RFID is “Radio Frequency Identification” — a technology that allows machines to read signals from RFID Chips implanted in passports and credit cards to transact over a short distance. RFID technology is a critical component of modern contactless payments, but it has raised concerns about possible vulnerabilities to criminal manipulation.
What is RFID blocking?
RFID blocking is the process of making your RFID-enabled device resistant to unauthorized access. The most popular way to achieve this is by getting an RFID blocking card — a card for your cards that is made from materials that interfere with electromagnetic fields.
RFID blocking technology was developed to prevent criminals from taking advantage of no-authorization contactless scanning. In theory, a thief standing nearby could surreptitiously access your card’s RFID function in what is known as a “Skimming Attack”, leeching money from victims in the street, a crowded bus, or a queue at the grocery store.
