Secrid Wallet

Available at Starlet

Blocks unwanted reading of RFID
[RFID = Radio Frequency IDentification]
If your RFID cards, such as the Oyster card, ID cards or the latest generation of credit cards, are not adequately protected, they can be detected and copied from a distance, without you noticing.
This can happen anytime, anywhere and by anyone who has a wireless cardreader, because the radio waves will easily cross any fabric or leather. The Secrid Cardprotector will protect your cards by effectively blocking these radio waves.
