Introduction - ACS ACR33U-A1 Smart Duo Reference Manual

1.0. Introduction

The ACR33U-A1 SmartDuo PC-Linked Reader acts as an interface for the communication between a
computer and a smart card. Different types of smart cards have different commands and different
communication protocols, which, in most cases, prevent direct communication between a smart card
and a computer. The ACR33U-A1 SmartDuo Smart Card Reader establishes a uniform interface from
the computer to the smart card for a wide variety of cards. By taking care of the card's particulars, it
releases the computer software programmer from being responsible with smart card operations'
technical details, which in many cases, are not relevant to the implementation of a smart card system.
