Introduction
This document provides instructions for software developers who want to create software solutions that
include a MagTek Secure Card Reader Authenticator (SCRA) device connected to an Android device via
the Audio/Headset Interface, Bluetooth, BLE (Bluetooth 4.0 Low Energy), or USB.
1.1
About the MagTek SCRA Demo
The MagTek SCRA Demo, available from MagTek, provides demonstration source code and a reusable
MTSCRA library that provides developers of custom software solutions with an easy-to-use interface for
aDynamo, uDynamo, Dynamag, DynaMAX, eDynamo, and BulleT readers. Developers can include the
MTSCRA library in custom branded software which can be distributed to customers or distributed
internally as part of an enterprise solution.

Nomenclature
The general terms “device” and “host” are used in different, often incompatible ways in a multitude of
specifications and contexts. For example “host” may have different meanings in the context of USB
communication than it does in the context of networked financial transaction processing. In this
document, “device” and “host” are used strictly as follows:
Device
refers to the reader device that receives and responds to the command set specified in this
document.
Host
refers to the piece of general-purpose electronic equipment the device is connected or paired to,
which can send data to and receive data from the device. Host types include PC, laptops, tablets,
smartphones, and even test harnesses. In many cases the host may have custom software installed on
it that communicates with the device. When “host” must be used differently, it is qualified as
something specific, such as “USB host.”
