- 🛡️ Use protected covers: Metallized mesh covers (such as RFID-blocking) block unauthorized reading.

Also avoid using NFC in public places with large crowds (metro, concerts), where attackers can read data from a distance of up to 10 cm. If you suspect that your smartphone has been compromised, check the payment history in the banking application and, if necessary, block the card.
