2. 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 PCSCcompliant 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.
