1.0. Introduction
The ACR83, a cost-effective PC-linked PINpad Reader, serves as 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 communication protocols, and the ACR83 PINeasy establishes a uniform
interface from the computer to the smart card for a wide variety of cards.
The ACR83 is connected to the computer through a USB interface and uses the CCID interface to
communicate with the USB port. CCID is the Device Class Specification for USB chip/Smart Card
Interface Devices, and defines the communication protocol and commands for the USB chip-card
interface devices.
Furthermore, the ACR83 supports CCID Secure PIN Entry (SPE) functionality which provides a
secure user interface for PIN entry without the danger of the PIN being observed by a third party.
ACR83 is a specific smart card reader which can do the PIN verification and modification in the card
reader.
