Unquestionably efficient, this metal shielded pouch has done its job: help but go read the contents of the RFID chip of the card in it. With this reading of contactless technology that develops, with mainstream tools that allow counterfeiters to retrieve your personal data (identity card, bank card, ...) without that you are aware of, two precautions are better than one. If you have several cards ... you have several pouches and then ... it becomes very heavy in the pocket, in the bag! I also bought a pocket that allows to place several cards with the same amount of protection against magnetic readers.
