What is RFID?
RFID or Radio Frequency Identification is an automatic identification method that uses wireless non-contact radio frequency waves in which data is digitally encoded in RFID tags or smart labels which can be read by reader through radio waves. The transfer of data takes place between a reader and a movable thing that can be identified & track.
RFID can be considered similar to barcodes as data read from tags are stored in database. However, unlike bar codes, RFID tag data can be read outside line-of-sight, doesn’t require any physical contact between reader and tagged item.
FID chips (often called tags) embedded in credit cards, passports, packages and more, are triggered by a nearby RFID reader or scanner.
RFID theft occurs when someone uses their own RFID reader to trigger the chip in your credit card; a process called ‘skimming’ or ‘digital pickpocketing.’
Typically, it involves the illegitimate reading of RFID-enabled credit cards (or other devices) at a distance in order to download the card’s information. The information can then be written to a new blank card, which operates in the same manner as the original, legitimate card.
Because the data is identical on both cards, and the information is only copied, it makes no difference if the original data is encrypted.
In most instances, a thief would need to be within 6 inches of the card to read it.This might occur on a crowded subway, in a museum, or even while walking by you. A thief can then use your credit card number to make other purchases from less secure sources such as online or abroad.
How do I know if my card has an RFID chip?
It is pretty easy to tell if your card/ passport is RFID enabled.
This symbol is used on RFID enabled passports in the US.
Around 120 countries including the US, UK, and Germany already have biometric e-passport systems in place. India is soon to enable e-passports with RFID chips as well.
How do Supervek wallets protect you from RFID theft?
A material designed to block RFID signals is included in the Supervek wallet lining. While your cards or passport are wrapped inside that material, a scanner will not be able to read the information inside.
