2.0. AET62 Contactless Smart Card Reader
The AET62 is a PC-linked contactless smart card reader/writer used for accessing ISO14443-4 Type
A and B, Mifare, ISO 18092 or NFC, and FeliCa tags. The AET62 Smart Card Reader is PCSC-
compliant so it is compatible with existing PCSC applications. Furthermore, the standard Microsoft
CCID driver is used to simplify driver installation.
The AET62 serves as the mediating device between the personal computer and the contactless tag
via the USB interface. The reader carries out the command issued from the PC, whether the
command is used in order to communicate with a contactless tag or control the device peripherals (i.e.
bi-color LED).
The AET62 uses the PCSC APDUs for contactless tags following the PCSC Specification and makes
use of pseudo APDUs in sending commands for ISO 18092 tags and controlling the device
peripherals. This document will discuss how you can use the AET62 in your smart card system.
