Anti-skimming Card RFID blockers are the same shape and size as a regular credit card and contain a special contactless chip jams the signal and prevents unauthorized access to the information of nearby credit cards and other cards with a contactless chip.
The anti-skimming chip works with the same principles as other passive RFID cards. When the card is not in the range of a reader, it doesn’t emit any signals. However, when it comes within reach of a reader or criminal scanner, it emits the jamming signal. Anti-skimming card RFID Blockers are jamming the signals on a frequency range 10 MHz to 20 MHz and they are suitable for protecting different kinds of RFID and NFC cards operating at a frequency of 13.56 Mhz. The anti-skimming card beside the blocking chip and antenna does not contain batteries or other electronics.
To protect your credit cards you have to place them close to the anti-skimming card.
A single anti-skimming card can protect multiple credit cards and it works within a range of 3 cm.
For protecting multiple, we recommend using two protective cards, one on each side of the cards you like to protect.
