| You have seen these machines at convenience stores. Maybe you have used one. You just place your credit card close to them and "Wha-la" it charges your credit card. Electronic pickpockets get your credit card information just by walking close to you.
Credit card protectors fit inside your pocket book or wallet. Credit card protective sleeve blocks the transmission of High Frequency 13.56 MHz or UHF 860-960 MHz Frequencies used by contactless credit & debit cards. Made from proprietary adhesives and layers of substrates that block the RFID transmission of personal data.
Sleeve Dimensions: 2 1/4" X 3 3/8"
A contactless credit card is different from an ordinary credit card. A contactless credit card uses RFID technology to store information about your account and to transfer it to the merchant. IT'S THE WAVE OF THE FUTURE! Standard credit cards carry data on a magnetic strip; when the card is swiped against a reader, the data is transferred. It is expected that, by the end of 2006, between 35 and 50 million contactless cards will be in use in the United States at as many as 50,000 merchant locations.
RFID-based credit cards, ID badges, passports and keychain passes are designed to be brought close to a reader. The reader has an antenna that emits radio waves; the tag responds by sending back its data. Radio-frequency identification (RFID) is a technology that uses communication via electromagnetic waves to exchange data between a terminal and an electronic tag attached to an object, for the purpose of identification and tracking. Some tags can be read from several meters away and beyond the line of sight of the reader.
