About RFID Blocking Credit & Debit Card Protector LED
1) How does this blocking card work? This is REAL Blocking Card and it is a passive one. It needs no battery. This blocking card draws energy from the sniffer to power up and instantly creates an EField , a surround electronic field making all 13.56 mhz cards (such as credit card, debit card, ID card, e-passport) invisible to the sniffer. This blocking card repels and scrambles the sniffers' signals. Once a sniffer is out of range the blocking card loses power. 2) What is this blocking card made from ? The surface of this blocking card is a PVC material. Inside this blocking card is a piece of circuit board (With LED) rather than a tinfoil or aluminum. 3) What is the size of this blocking card ? It is designed as the size of a standard PVC card, and the thickness is 1.2 mm. 4) How many 13.56mhz cards can this blocking card protect at a time ? It can protect 10~15pcs RFID 13.56mhz cards at a time and you just need to put one card in the wallet . 5) How do we know if it works? Please take this LED RFID Blocking card near to you NFC Mobile phone (need open NFC function frist) , then the LED will be light. Or put the RFID Blocking card with your Access IC Card together near to the reader, then the access IC card can’t be read again.
