1.0. Introduction
The ACR1281U-C8 is the new version of ACS’s ACR120U Contactless Smart Card Reader. The
ACR1281U-C8 USB Protocol defines the interface between the PC and the reader, as well as the
communication channel between the PC and the supported contactless cards, including Mifare
®
, ISO
14443 Type A and B compatible cards. By using the High Level APIs, the users can develop
applications that involve the use of contactless cards with minimum effort. For example:
•
Access control, Identification:
Reading the serial numbers of all cards in the field
•
Data Storage:
Performing encrypted read and write operations
•
Ticketing:
Performing read, write, increment and decrement operations in an encrypted
environment
•
Multi applications:
Performing read, write, increment and decrement operations on various
sectors of the card
