RFID cards are contactless payment cards that use radio waves to communicate with readers. They are as secure as EMV chip cards, as they use one-time codes and encryption to protect data. But they can also be hacked or skimmed by scanners or fake readers. So, when using RFID cards, remember to:
• Keep them in a safe place, like your front pocket or a zipped bag.
• Use an RFID-blocking wallet or sleeve to block radio signals.
• Be careful of people or devices around the payment terminal, and avoid being tricked.
• Check your bank statements regularly and report any suspicious transactions or charges.
RFID cards are convenient and hygienic, but you need to take some security measures to use them safely.
