The ACR1581 DualBoost III is a highly advanced and versatile smart card reader that can support both contact and contactless smart cards. It is the third generation product in the ACS's DualBoost Reader Series, which has been designed to offer high levels of security and reliability for demanding smart card applications. The reader makes use of USB CCID Class Driver and USB Interface to establish a connection with PCs and accept card commands from computer applications.

One of the main advantages of the ACR1581U is its broad support for various types of smart cards, including traditional ISO 7816 MCU Cards, MIFARE® Cards, ISO 14443 Type A and B Contactless Cards, FeliCa, and ISO 15693 Cards. It also has three interfaces, the PICC, ICC, and SAM interface, which all follow the PC/SC specifications. This makes it suitable for use in various industries, such as finance, healthcare, and government.

The ACR1581U acts as an intermediary device between the computer and the card, carrying out computer-issued commands for communication with contactless tags, MCU cards, SAM cards, or device peripherals (LED or buzzer). It also offers intelligent support for keyboard emulation and card emulation, making it versatile for various smart card applications. The contact interface makes use of the APDU commands as defined in ISO 7816 specifications, and for contact MCU card operations, the related card documentation and the PC/SC specifications should be referred to.

Overall, the ACR1581 DualBoost III is a powerful and flexible smart card reader that offers a wide range of advanced features and capabilities. Its ability to support both contact and contactless smart cards, along with its broad support for different types of smart cards, makes it an ideal choice for a wide variety of smart card applications that require high levels of security and reliability.
