Digital Pickpocket Scam Exposed: RFID & NFC - Pros & Cons | LMES

RFID technology uses electromagnetic induction to enable contactless payments, where changing magnetic fields induce currents in conductive materials like copper coils, allowing cards to transmit encrypted transaction data to bank servers for verification; however, this same principle can be exploited through 'ghost tapping' scams where attackers use specialized scanners to read transaction data without physical contact, and the solution involves Faraday shielding using conductive materials like aluminum foil that create opposing eddy currents to block the magnetic field and prevent unauthorized scanning.
