Contactless payments are fast and convenient. Simply hold your card near the terminal, and the payment is completed within seconds. However, this technology raises an important question: can someone scan your card while it is still inside your wallet?
This is where RFID skimming comes into the picture.
What is RFID skimming?
RFID skimming is the unauthorized reading of data from a contactless card using a suitable scanner. Payment cards commonly use NFC, a short-range technology that belongs to the broader RFID family.
In theory, an attacker could bring a concealed reader close to your wallet, handbag, or pocket and attempt to capture the data transmitted by your card. However, this does not mean that the card can simply be copied and used for unlimited purchases.
Modern contactless payments use one-time security elements generated for individual transactions. According to Visa, this makes it difficult to use intercepted information for fraudulent payments and limits the potential risk. An accidental payment made simply by walking past a terminal is also highly unlikely. The merchant must first initiate the transaction, and the card must be held very close to the reader.
How can you reduce the risk?
Start by regularly checking your account activity and enabling notifications for every payment. If you notice an unfamiliar transaction, contact your bank immediately and have the card blocked. You should also avoid lending your card to others or leaving it unattended.
If you want to reduce the possibility of unauthorized contactless scanning, you can use a shielded card sleeve, an RFID-blocking wallet, or a protective card.
For example, the FWR anti-skimming card can be placed directly inside your wallet alongside your other cards. When an RFID or NFC scanning attempt occurs, it creates an interfering signal around itself that helps prevent nearby cards from being read. It does not require a battery or charging and takes up approximately the same amount of space as a standard payment card.
A sensible approach is what matters most
RFID skimming is not a reason to panic or stop using contactless payments. Today’s payment cards use several layers of security, and successfully misusing data captured from a contactless card is not straightforward.
Nevertheless, it is useful to understand how the technology works, monitor your account regularly, and consider adding a simple physical layer of protection to your wallet. When it comes to security, a combination of modern technology, awareness, and a few small preventive measures often works best.
