RFID (Radio Frequency Identification) is a technology that uses radio waves to wirelessly transfer information. Contactless cards like credit/debit cards, passports, and public transport cards use RFID to send data when scanned. While these cards offer great convenience for payments, they also come with a significant security threat.

 

Hackers use special RFID scanners to read the data on your card. This puts your personal and financial information at risk of theft, often without your knowledge. The most alarming part is that hackers can steal your information from a distance, especially in crowded public places, making it easy for them to escape undetected.
