The product is not much larger than a credit card. With a simple press of a finger and without opening it, a maximum of 5 cards slide out automatically in a staggered manner. Thanks to the clever "One-Touch" technology, the Click & Slide can be easily operated with just one hand. The inner aluminum case protects your cards from illegal data theft from NFC/RFID chips and demagnetization. The leather cover made of the finest Italian leather provides additional space for more cards, business cards, and banknotes, and has the added advantage of allowing "Tap and Go" cards to be used conveniently.
