1.0. Introduction
The ACR89U-A2 Handheld Smart Card Reader with NFC tag support is a versatile dual interface
smart card reader with PINpad, which can be used to access ISO 7816 MCU cards, ISO 14443 Type
A and B, MIFARE®, FeliCa and ISO 18092 or NFC tags. It can operate in both office and field-based
environments using it PC-linked and standalone modes, respectively.
For PC-linked Mode, ACR89U-A2 acts as the intermediary device between the PC and the card. The
reader, specifically to communicate with a contactless tag, MCU card, SAM card or device
peripherals, will carry out a command issued from the PC.
This manual describes the use of ACR89 software programming interface to control the built-in
accessories of the ACR89 multi-functional card reader. Built-in accessories are defined to be the
keypad, LCD display, LEDs, buzzer and real-time clock, embedded in ACR89. Such components are
not controlled through the smart card reader library. In addition, this document provides a guide on
implementing PC/SC APDU commands for device contactless tags.
