This wallet from the Secrid brand is well-equipped and contemporary for banknotes and cards. Nobly packaged, they are well protected for everyday use. 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 ID cards, debit and credit cards and sometimes also in smartphones and enable cashless payment without a signature or PIN entry, for example. Thanks to a coating on the card or mobile phone compartment that is impermeable to radio waves, this product protects the data from unauthorised reading by third parties.
