RFID-blokerende pashylster

Introduktion til produktet:

The RFID blocking passport sleeve is designed based on the Faraday cage principle. RFID communication is a wireless communication technology that uses electromagnetic alternating fields for signal transmission. This electromagnetic field propagates on the surface of the shielding sleeve that conforms to the Faraday cage principle and is “transparent” to the other side of the sleeve, However, no alternating electromagnetic field can be detected in the holding chamber of the shielding sleeve (because according to the Faraday cage principle, the internal potential is equal everywhere and there is no moving charge). Therefore, the RFID chip inside the shielding sleeve will not respond to external electromagnetic field communication, making it impossible for RFID devices to obtain card information even when they are close to the card in the shielding sleeve, effectively ensuring the information security of the card.
