ACR128U Contact and Contactless Smart Card Reader and Writer
1.0
INTRODUCTION
The ACR128U is a Contact and Contacless Smart Card Reader and Writer
developed on the 13.56MHz Contactless Technology. This device is a dual-interface
reader (IFD and PCD) that supports both contact (ICC) and contactless (PICC) smart
cards. It is designed to support ISO 7816 Parts 1-4 and ISO14443 Type A and B Cards,
Hybrid Cards and Combi Cards but not FeliCa tags.
High-speed (424 kbps) communication for PICCs (Maximum 848 kbps). Energy saving
modes for turning off the antenna field whenever the PICC is inactive, or no PICC is
found. It prevents the PICC from exposing to the field all the time. I t can support USB
V2.0 interface and the speed up to 12Mbps. This device Firmware Upgradeable through
the RS232 Interface with a special cable can more easily.
