• In terms of standalone application development, what’s the difference between ACR88 and ACR89?

  ACR88 uses proprietary script language which imposes more limitations on functions and programmable size. Meanwhile, ACR89, having embedded FreeRTOS, uses C language, which is familiar to many users. C language also has more flexible functions and larger programmable size than those provided by the ACR88. The multi-tasking environment provided by FreeRTOS also makes it easier to develop complex applications.

• If clients want to migrate from the ACR88 to the ACR89, what should they do?

  They need to take some time to port their old standalone application to ACR89. It would not be too complex compared to the ACR88 which poses limitations on scripting language. And also, most programmers know how to use C language.

• What is the embedded operating system of the ACR89 reader?

  The ACR89 is equipped with 32-bit CPU running the embedded Free RT operating system kernel. It is opensource, portable, free to download, and free to deploy. It is a very portable code structure predominantly written in C language.

• What is FreeRTOS?

  The FreeRTOS kernel is a scalable real time kernel designed specifically for small embedded system. It is designed to be small, simple and easy to use. It is assumed that the user has familiarity in using the C programming language. Refer to this link for the details about the Free RTOS software environment:http://www.freertos.org/

• How is a standalone application developed using ACR89 system?

  The Software Development Kit will provide a tool that is used to compile a program written in C programming language using Free RT operating system. The kit will also provide a sample application demo as well. In addition to that, an Application Programming Interface document is provided to program the ACR89.Refer to this link for the API document: http://www.acs.com.hk/en/drivers/

• How do I access ACR89 from the PC?

  You can perform commands to control ACR89 and its peripherals. One such application provided in the software development kit is the ACS Smart Card Reader Tool. It helps you identify basic information, memory information and default settings; identify the status of inserted cards; test the functionality of the peripherals; and extract the device transaction logs performed during the standalone demo in csv format for report-generation purposes.
