RFID secure wallets protect against RFID skimming. RFID skimming is a type of electronic pickpocketing where thieves use a handheld device to scan and capture the RFID information stored on credit cards and debit cards. This information can then be used to make unauthorized charges. RFID secure wallets are designed to protect against this type of theft, by blocking the signal from the RFID chip and making it impossible for thieves to read the RFID information stored on your cards.
