The product is not much larger than a credit card. With just a finger press and without opening it, a maximum of five cards slide out automatically in a staggered formation. 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 against 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 that "Tap and Go" cards can be conveniently used.
