Radio Frequency Identification, or RFID, refers to a technology for retrieving data stored on a special chip via radio waves. Such RFID chips are used in new identity cards, debit and credit cards, and sometimes even in smartphones, enabling cashless payments without a signature or PIN entry. With a coating that is impermeable to radio waves in the card or phone compartment, this product protects your data from unauthorized access by third parties.
