An example of no-frills quality is the classic wallet from Braun Büffel with functional features and special protection for your data.

Radio Frequency Identification, or RFID for short, is a technology for retrieving data stored on a special chip via radio. Such RFID chips are used in the new identity card, in EC and credit cards, and sometimes also in smartphones, and enable cashless payments without a signature or PIN entry. Thanks to a coating on the card or mobile phone compartment that is impermeable to radio waves, this product protects your data from unauthorised reading by third parties.
