Aluminium RFID proof credit card case.

People have been concerned about RFID chips for many years now, and not just in credit cards. The key is that RFID chips have tiny electromagnetic fields, which is what makes it possible to read one without having to “initiate” communications. The RFID reader just needs to be close enough to get within the field.That’s why, in theory, somebody could scan a card through your pocket. 

Fortunately, radio waves are relatively easy to interrupt and block, and that’s how an RFID-blocking wallet works. They encase your credit cards in a material that interferes with radio waves. It will block all electromagnetic fields and prevent communication between your cards and RFID scanners.
