Enable perfect arrangement of your important cards with this extensible aluminium card holder that is held with elastic straps for holding the cards in place. This portable card holder is able to hold about 10-15 business cards. This aluminium pouch also features an impressive RFID blocker to protect the cards (like credit cards, business cards etc.) from cyber hackers by preventing data transfer between the wallet and the reader. This blocker works with only contactless chip cards as they do not protect cards that are swiped.
