The ACR122 is a PC-linked Contactless Smart Card Reader/Writer developed on the 13.56MHz 
Contactless Technology. This device is designed to support not only MiFare and ISO14443 Type A and 
B Cards but also FeliCa and NFC tags.  
 
This reader follows the CCID Standard which allows Windows Operating Systems to use the Microsoft 
CCID drivers. However, Advanced Card Systems Ltd (ACS) also provides WHQL drivers which can be 
installed in your machine. Read and write operations to contactless tags are also faster and more 
efficient since the device makes use of a high-speed card access and a full USB speed of 12 Mbps.  
 
The ACR122 NFC Reader SDK provides the user sample applications, sample codes, and tools and 
utilities that can be used to experience the features and capabilities of the ACR122.  This manual gives 
the summary on how to install the SDK and what can be found in the SDK.  
 
Together with its compact size, trendy design, and various features, the ACR122 offers users a different 
experience of convenience by using it for applications such as payment, mass transit, physical access 
control, time attendance, etc.
