ACR38 Reference Manual version 1.9 February 2006

1. Introduction

The ACS Smart Card Reader/Writer ACR38 is an interface for the communication between a computer (for

example, a PC) and a smart card. Different types of smart cards have different commands and different

communication protocols. This prevents in most cases the direct communication between a smart card and

a computer. The ACR38 Reader/Writer establishes a uniform interface from the computer to the smart card

for a wide variety of cards. By taking care of the card specific particulars, it releases the computer software

programmer of getting involved with the technical details of the smart card operation, which are in many

cases not relevant for the implementation of a smart card system.

The ACR38 Smart Card Reader/Writer is connected to the computer through USB interface. The reader

accepts commands from the computer, carries out the specified function at the smart card and returns the

requested data or status information.

NOTE - Although the ACR38 is a true card reader/writer as it can read and write smart cards, the terms card reader or reader will be

used indifferently to refer to the ACR38, for the sake of readability and because these designations are commonly in use for this kind of

devices.
