1. Introduction
This document aims to describe how to operate the SR272A; SR272B hardware, and the
connectivity of the reader to the host.
1.1. About the Reader
The SR272A; SR272B reader is NFC reader with support for SIM-sized smartcards.
•Supports up to 8 ISO7816 Class A, B and C (5 V, 3 V, and 1.8 V) SIM-sized smartcards.
•Supports ISO14443 microprocessor cards with T=0 or T=1 protocol with PPS, and
ISO14443 memory cards.
•User-controllable RGB status LED.
•User-controllable buzzer.
•Driver-free PC/SC operating mode.
The reader complies with FCC/CE regulations, TUV shock-and vibration tests for use in transit
environments.
