When using a wallet with several wireless tag recognition electronic cards embedded with a magnetic device or a chip semiconductor such as smart cards, credit cards, check cards, or traffic recognition cards, several cards are recognized at the same time or they are not recognized. Such different kinds of problems can be prevented in advance by covering all the cards except for a card to use with wireless recognition prevention pockets or attaching wireless recognition prevention stickers to all the cards except for the card to use. |
