How does RFID blocking card work?
RFID chips work by using radio waves to communicate. The object, such as a credit card, contains an RFID tag with information, and an RFID reader uses radio waves to read the information from a tag. The key is that RFID chips have tiny electromagnetic fields, which is what makes them possible to read without having to “initiate” communications. All you need is proximity.
Fortunately, radio waves are relatively easy to interrupt and block, and that’s how an RFID-blocking card works: they encase your credit cards in a material that interferes with radio waves
