ACS ACM1281 User manual

  • Hello! I've reviewed the user manual for the ACM1281 Contactless Reader Module, which includes the ACM1281U-C (USB) and ACM1281S-C (serial) versions. I understand it supports various cards and has a SAM slot for enhanced security. I'm ready to answer your questions about its features, setup, or how to integrate it into your systems.
  • What card types are supported?
    What is the maximum card reading distance?
    What interfaces are available for connecting the module?
    What is the maximum communication speed?

1.0. Introduction The ACM1281 is a Contactless Reader Module with SAM Slot
designed based on the 13.56 MHz technology. It supports ISO
14443 Parts 1-4 Type A and B cards, and MIFARE® Classic
series with a card reading distance of up to 50 mm (depending on
tag type).
The ACM1281 comes in a module form factor with different
interface versions: ACM1281U-C is a USB version and
ACM1281S-C is a serial version. It is specifically designed for fast
and easy integration to embedded systems. It also has an ISO
7816 Compliant built-in SAM (Secure Access Module) slot which
can be used together with a SAM card for high-level security in contactless transactions.
The ACM1281 has an integrated (on-board) antenna and comes with an optional USB and serial
cables, and has additional features like USB firmware upgradability and extended APDU support.
Lastly, the ACM1281 makes use of high-speed communication for contactless cards at a maximum of
848 Kbps, which makes it suitable for highly demanding applications such as vending machine
payment systems, kiosks, gaming machines and other integrated systems which have different serial
ports.

2.0. Pin Assignment
2.1. Configuring the LED operations status
There are two LEDs on ACM1281 to display its operation status:
Red is for power
Green is for smart card operation
Figure 2: ACM1281 LED Configuration
2.1.1. LED Behaviors
To control the LED’s output and checking the LED’s behavior for smart card operation status, you
may refer to the following document:
ACM1281U-C: ACR1281U Reference Manual
ACM1281S-C: ACR1281S Reference Manual
The reference manuals will discuss the detail how PC/SC APDU commands were implemented for the
contactless interface and device peripherals of ACM1281U and ACM1281S.
