1. Introduction
The AET62 is a composite device, consisting ACS’ ACR122U NFC Reader’s core and UPEK’s swipe fingerprint sensor.
The NFC contactless smart card reader and the fingerprint sensor can be used independently, but combining the two
technologies provide a higher level of security in applications.
The AET62’s system diagram is shown below:

The purpose of this document is to describe the architecture and interface of AET62’s contactless smart card reader
module, which is based on the ACR122U core. For information on the architecture and programming interface of the
fingerprint module, please refer to the AET62 Fingerprint Reader Application Programming Interface document
(API_AET62_v1.0).
