Along with the rapid growth of technology comes the increasing prevalence of electronic data theft. This emphasizes the need to secure electronic data, thus necessitating the integration of smart card technology into current IT infrastructures. Following this trend, the ACR38 Smart Card Reader Series combines sophisticated technology and modern design to meet stringent requirements in smart card-based applications, such as payment systems and electronic identification, where a high level of security has increasingly been deemed essential.

Being compliant with the CCID specification, the ACR38 Series offers a plug-and-play solution that eliminates the need for driver installation and driver-system compatibility assessment. Its USB interface facilitates communication between a computer and a smart card very easily, allowing for a seamless implementation of smart-card based applications in a PC environment.

ACR38 Smart Card Reader is compliant with ISO 7816 and EMV Level 1 specifications. It supports ISO 7816 Class A, B and C ( 5V, 3 V and 1.8 V) cards, including all microprocessor cards with T=0, and T=1 protocols, as well as most of the popular memory cards in the market.

ACR38 also offers an optional built-in Security Access Module (SAM) slot - ACR38U-SAM that supports various high security applications. It is also available in different casing designs, including the new ACR38U-I1 which is now FIPS 201 certified and TAA compliant. In addition, ACR38 also has an alternative reader module form (ACM38).
