ACR39U-W1 is a sleek and stylish device that features an innovative dual slot design to accommodate two smart cards simultaneously. 

ACR39U-W1 supports ISO 7816 Class A, B and C smart cards (5 V, 3 V, 1.8 V), microprocessor cards with the T=0, T=1 protocol, and a wide variety of memory cards in the market. The competitive advantage of ACR39U-W1 lies on its dual slot feature that allows users to operate two smart cards at the same time, enabling efficiency and enhanced security in smart card applications. As an example, one slot can hold the smart card of an authorized personnel managing a particular smart card-based service, while the other slot can be used by various individuals availing of such service. 

Through ACR39U-W1’s dual slot solution, the card slots can work independently resulting in smoother and uninterrupted flow of transactions.

Compliant with both CCID and PC/SC, ACR39U-W1 can be used on Windows, Linux, Mac OS, and Android OS.
