ACR39U-W1
SmartDuo Smart Card Reader

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, the Malaysian Identity Card (Mykad), 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.  It is also highly durable as it is able to last for 100,000 card
insertion cycles.

Compliant with both CCID and PC/SC, ACR39U-W1 can be used on Windows®, Linux®, macOS,
and AndroidTM
