1 - Introduction

1.5 Security in Mind

Data is protected and encrypted the moment the card is swiped, so clear data never enters your system.
Open, 3DES end-to-end encryption and industry-standard DUKPT key management allow for greater
platform flexibility. Ask a representative for more information about MagTek and Magensa’s data
protection and transaction services.

1.6 Simplified Integration

MagTek understands the value of easy-to-use and well documented Software Development Kits (SDKs),
technical documentation, APIs, and sample code. MagTek SDKs have no royalties or maintenance fees
and are free to redistribute with your application. Use MagTek’s MagneFlex browser or middleware
application for even easier development.

1.7 MagneSafe Security Architecture

The MagneSafe Security Architecture provides the maximum security at the minimum cost, both in total
dollars and implementation effort. MagneSafe delivers a layered approach to transaction security, and
combines encryption, tokenization, authentication and dynamic data to protect card data at the moment
the card is swiped.

1.9 About Terminology

In this document, tDynamo is referred to as the device. It is designed to be connected to a host, which is
a piece of general-purpose electronic equipment which can send commands and data to, and receive data
from, the device. Host types include PC computers/laptops, tablets, and smartphones. Generally, the host
must have software installed that communicates with the device and is capable of processing
transactions. During a transaction, the host and its software interact with the operator, such as a cashier
or bank teller, while the device interacts with the cardholder.

1 - Introduction

1.10 About Solution Planning

A smooth deployment of a tDynamo solution requires some up-front planning and decision-making:
 Determine what type of host tDynamo will connect to. This can be a computer with a USB port or a

host with Bluetooth 4.0 hardware that supports Bluetooth LE. When planning, include any additional
support or devices required by the host, such as physical locations, mounting, and power connections.

 Determine what software will be installed on the host and how it will be configured. Software can

include operating system, transaction processing software, security software, and so on. Include any
additional support required by the software, such as network connections.

 Select which connection type the solution will use. tDynamo can connect physically via its USB-C

connector or to the optional docking stand, or via Bluetooth LE. It connects logically as a vendor­defined HID device or GATT device, respectively. Be sure to specify the desired connection settings
when ordering the device. If necessary, they can be reconfigured afterward.

 Determine how tDynamo should be configured, and specify that when you order devices. For

example, although tDynamo comes with a factory default Bluetooth LE passkey, it is a good idea to
choose and set non-default passkeys early in the planning process, or request non-default passkeys
when ordering devices.

 Determine what the solution will use as a primary power source. tDynamo can be powered by a

USB host through the USB-C connector or the optional docking stand, or can be powered by its
internal rechargeable battery.

 Determine the battery recharge schedule(s). For example, in high-traffic mission-critical solutions,

it may be wise to keep spare devices configured and charged for fast swap-out.

 Determine how tDynamo will be physically presented to the cardholder. This includes whether the

device will be handheld, permanently mounted to a countertop in the optional docking stand, or
handheld and placed in the docking stand for easy charging. When planning placement, be sure to
consider the connection type and power source. For example, if the primary data connection is USB,
the mounting location should be within reasonable USB cabling distance from the host.

 Determine how tDynamo will be branded. In large quantities, MagTek can accommodate custom

branding colors and trade dress. Contact a representative for details.

2 Installation

Installing tDynamo is a straightforward process: The acquirer configures the encryption keys and EMV
terminal / payment brand settings before deployment. End users need only set up a host with appropriate
software, configure the software, and connect the device to the host. This section provides general
information about setting up solutions that incorporate tDynamo, including host software, connecting the
device, and mounting the device.

2.1 About Host Software

In any solution, tDynamo is connected to a host, which must have software installed that knows how to
communicate with the device, and which is capable of performing actions intended to be carried out when
a cardholder swipes, inserts, or taps a payment method. To set up the host software to work with
tDynamo, follow the installation and configuration instructions provided by the vendor of the host or the
host software. For details about developing host software, see section 5 Developing Custom Software.

Some connection types may also require installation of device drivers on the host. To set up any
necessary drivers, see the connection-specific “How To” sections in section 2.2 Connecting to a Host.

2.2 Connecting to a Host

2.2.1 About Connecting tDynamo to a Host

tDynamo can connect to a host via a variety of connections. Solution designs generally choose one
connection type and do not switch between them, though the device does provide features that allow the
host to actively manage its active connections and connection behaviors (see section 5 Developing
Custom Software). The following sections provide steps for connecting tDynamo to a host via each
connection type.

2.2.2 How to Connect tDynamo to a Host Computer via USB

tDynamo can connect to a USB host or charger either via its USB-C Connector or the optional docking
stand. If the device is using USB as a power source but not as a host connection, also see the sections
below about connecting the device using Bluetooth LE. If the device is connected to two USB
connections at the same time, the docking stand connection takes precedence as a power source, and the
device’s configuration determines which connection it uses to send card swipe data.

To connect tDynamo to a host computer using the optional docking stand, see section 2.3 Mounting
tDynamo. To connect tDynamo to a host computer using the USB-C Connector, follow these steps:

1) Make sure tDynamo is configured to use the USB-C connector as its primary connection. If it is

configured to use another connection, use that connection first to change the configuration.

2) Connect the small end of the USB cable to tDynamo’s USB-C connector as shown in Figure 2-1.

3) Connect the large end of the USB cable to the host computer’s USB port.

4) Power on the host computer.

5) On the host, install and configure the host software you intend to use with tDynamo (if you do not yet

have that software, you can use MTNETDemo.exe included in SOFTWARE, SDK, DYNAMAG /

DYNAMAX / EDYNAMO / UDYNAMO / ADYNAMO / MDYNAMO / TDYNAMO /
DYNAWAVE (WINDOWS .NET), available from MagTek.com, to perform simple tests):

a) Make sure the host software is configured to look for the device on the proper connection type.
b) Make sure the host software knows which device(s) it should interface with.
c) Make sure the host software is configured to properly interpret incoming data from the device.

For direct USB connections, tDynamo transmits data as a vendor-defined HID device.

6) Use the host software to test swiping, inserting, and tapping a card (see section 3.5 Card Reading).

2.3 Mounting tDynamo

2.3.1 About Mounting

tDynamo’s design provides two mount points: A Lanyard Mount Point and a Locking Mount Point
(see section 1.8 About tDynamo Components). The two mount points can be used in various
combinations:

 The lanyard mount point can be used to hang the device for convenient hanging storage and/or

handling in handheld sales solutions.

 The locking mount point can be used with the optional docking stand (shown in Figure 2-2) mounted

to a countertop for stability in stationary sales solutions.

 The locking mount point can also be used with custom brackets to mount to other devices or surfaces.
 The docking stand can also be used in unlocked mode, and optionally combined with the lanyard

mount point, for quick grab-and-go and convenient drop-in charging between handheld sessions.

2.3.2 How to Mount the Docking Stand

To mount the docking stand to a countertop, follow these steps (see Figure 2-3):

1) Determine where the docking stand should be placed: Factors to consider include cable length,

cardholder and operator ergonomics, and access for cleaning and repair.
a) If the docking stand will be used for charging in handheld operations, unobstructed removal is

also a consideration.

b) If the device will be permanently docked for cardholder use, placing the stand so it hangs slightly

over the edge of the surface may provide the least obstructed swipe path.

2) Open the protective cap over the mounting hole on the base of the docking stand.

3) Place the docking stand at the desired location and mark the center of the mounting hole on the

countertop, then set the docking stand aside.

4) Drill a ¼” hole all the way through the countertop.

5) Line up the hole in the stand over the hole in the countertop.

6) Thread the included bolt through docking stand’s mounting hole and the countertop hole.

7) Fasten the included knob to the bolt and tighten it.

8) Replace the docking stand’s protective cap.

9) Connect the docking stand’s USB cable to the host.

3 - Operation

3 Operation

3.1 About Operating Modes

During operation, tDynamo transitions between six distinct modes, each of which behaves differently:
 Reset Mode occurs when the user presses and the recessed reset switch or holds the pushbutton for 5

to 10 seconds. After resetting, the device progresses to Powered Off Mode. If the device is
connected to USB power, it immediately progresses to Discoverable Mode.

 Powered Off Mode is the shipping mode of the device. The operator can power off by pressing and

holding the pushbutton, and the device enters this mode automatically if it has been in Sleep Mode for
a configurable timeout period. When powered off, the device consumes practically no power. To
move the device from Powered Off Mode to Discoverable Mode, press the pushbutton briefly or
connect the device to a USB charger or USB host. When the device is connected to a host via USB,
the device immediately progresses to Connected Mode.

 Battery Status Mode is a short mode that uses all four Status LEDs to report the current charge level

of the device’s rechargeable battery (see section 3.4.1 About Power). The operator activates this
mode by tapping the pushbutton briefly in Discoverable Mode or Connected Mode. The device
automatically exits to the previous mode after a short period of time.

 Discoverable Mode is the device’s normal waiting state. The operator activates this mode when the

device is not connected to USB by briefly pressing the pushbutton once while in Powered Off Mode.
In this mode, the device remains paired with any previously paired Bluetooth LE hosts, but is not
connected to transmit data. Upon entering Discoverable Mode, the device advertises itself over
Bluetooth LE, and any paired Bluetooth LE host may initiate a connection. To move the device from
Discoverable Mode to Pairing Mode, press and hold the pushbutton for about two seconds until the
General Status LED flashes, then release the pushbutton. If the device is not connected to USB
power, it will move from Discoverable Mode to Sleep Mode automatically when its configurable
timeout period has passed. If the device is configured to transmit data over USB and is connected to
a USB host, it immediately progresses from Discoverable Mode to Connected Mode.

 Pairing Mode is activated while the device is powered on by pressing the pushbutton for two seconds

and waiting for the General Status LED to flash, then releasing the pushbutton. In this mode, an
unpaired Bluetooth LE host may initiate pairing. Upon entering Pairing Mode, the device advertises
over Bluetooth LE, and continues to be pairable until a Bluetooth LE host pairs with it or until a
2-minute timeout period expires. Upon successful pairing, the device enters Discoverable Mode.

 Connected Mode occurs when the device is connected to a USB host, or when a paired Bluetooth LE

host initiates a connection (generally in response to the host software’s graphical user interface). In

this mode, the host and the device can both initiate communication, and it is the Bluetooth LE host’s
responsibility to terminate the connection and return the device to Discoverable Mode to save power
when an active data connection is no longer needed for the current transaction. If the device is not
connected to USB power, it will move from Connected Mode to Sleep Mode automatically when its
configurable Sleep Mode timeout period has passed. If the device is connected to a Bluetooth LE
host, it does not advertise and is not discoverable by other Bluetooth LE hosts. If the device is
connected to a USB host, it continues to advertise and is discoverable by Bluetooth LE hosts.

 Sleep Mode is a low-power standby state. The device enters this mode automatically when it is not

connected to USB power and has been unused (no user input, no communication with the host) for a
configurable timeout period. In this mode, the device turns off all Bluetooth LE functions. To move
the device from Sleep Mode to Discoverable Mode, press the pushbutton briefly or connect the device
to a USB charger. To move the device from Sleep Mode to Connected Mode, connect the device to a
USB host. The device moves from Sleep Mode to Powered Off Mode automatically when its
configurable Power Off timeout period has passed.

3.4 Power Management

3.4.1 About Power

tDynamo can be powered by one of two power sources: USB or the built-in rechargeable battery.

When the device is connected to a USB host or charger via the USB-C connector or the optional docking
stand, it receives power through the USB connection. In this case, the device powers on automatically,
recharges the built-in rechargeable battery, and stays powered on.

When the device is not connected to a USB power source, it receives power from its onboard
rechargeable battery. In this case, after a period of inactivity (no host commands and no user interaction),
the device transitions to a low-power Sleep Mode, which it indicates by turning the General Status LED
solid red and LED 3 solid green. When the device is already in Sleep Mode, after a further period of
inactivity, the device powers off completely and turns off all LEDs.

The host can set the device’s Sleep Mode and Power Off timeouts to values that are appropriate for the
specific solution design. For details about developing host software to configure the device, see section 5
Developing Custom Software.

For details about the device’s behavior in its various power modes, see section 3.1 About Operating
Modes. For instructions to check and recharge the battery, power the device on and off, and wake the
device from sleep mode, see the following sections.

3.4.2 How to Check Battery Level

To check the battery charge level, make sure the device is powered on and awake, then briefly tap the
pushbutton. The Status LEDs light to show the battery level as follows:

 One LED = Battery level is under 50%
 Two LEDs = Battery level is between 50% and 70%
 Three LEDs = Battery level is between 70% and 90%
 Four LEDs = Battery level is above 90%

Figure 3-1 - Status LEDs Showing Battery Level

tDynamo| Three-way Secure Card Reader Authenticator | Installation and Operation Manual

Page 29 of 39 (D998200257-20)

3 - Operation

When the device is in Connected mode (see section 3.1 About Operating Modes), the General Status
LED blinks periodically to indicate the device is ready for the host to send a command or for a cardholder
to swipe a magnetic stripe card. The color of the blink indicates the battery level. See section 3.2 About
the Status LEDs for details.

Custom host software may also query the device and show its current charge level on the host display at
all times for convenience. For details, see section 5 Developing Custom Software.

3.4.3 How to Charge the Battery

tDynamo has an onboard rechargeable battery to supply its own power when it is not powered through its
USB-C connector or docking stand connectors. The battery must be periodically recharged by connecting
it to the optional docking stand, or to a USB port or stand-alone USB charger using a USB-C cable. Both
the docking stand and the USB-C connector require a USB connection that can provide at least 500mA @
5V. A full recharge cycle for a completely drained battery takes approximately 4.5 hours.

To charge the device using a USB-C cable, connect it to a USB charger or to a USB host as shown in
section 2.2.2 How to Connect tDynamo to a Host Computer via USB.

To charge the device in the docking stand, see section 2.3.3 How to Temporarily Dock tDynamo.

3.4.4 How to Power On / Wake Up from Sleep Mode / Power Off

If all LEDs are off, the device is in Powered Off mode. If the General Status LED is solid red and LED 3
is solid green, the device is in Sleep Mode. To power on the device or to wake it from Sleep Mode, tap
the pushbutton. In response, the device lights all of the Status LEDs to perform a quick LED test, then
transitions to either Discoverable Mode or Connected Mode. For details, see section 3.1 About
Operating Modes and section 3.2 About the Status LEDs.

To power off the device, press and hold the pushbutton for 5 to 10 seconds until all LEDs turn off and the
device beeps twice.

3.4.5 How to Force Reset

To force the device to reset, use a small tool such as a paperclip to carefully press the reset switch
recessed inside the small hole on the back of the device (see Figure 1-1).

3.5 Card Reading

3.5.1 About Reading Cards

The steps for starting a transaction and reading a card or contactless payment device are different
depending on tDynamo’s configuration and on the design of the host software. Host software developers
should see section 5 Developing Custom Software for implementation references. The solution
developer should provide solution-specific instructions for operators to follow. A transaction generally
follows this essential flow:

1) An advanced operator makes sure tDynamo is configured properly and is connected to the host (see

section 2.2 Connecting to a Host). When the device is connected to the host via USB and powered
by the USB-C connector or docking stand, generally the host always keeps a connection open to the
device. When connected to the host via Bluetooth LE, the device must already be paired with the
host, and the host must be initiate a Bluetooth LE connection to process a transaction, then would
generally disconnect after the transaction is complete to conserve power.

2) The operator makes sure tDynamo is receiving power either from its rechargeable battery or from one

of the USB connections, and is awake and powered on (see section 3.4.4 How to Power On / Wake
Up from Sleep Mode / Power Off and section 3.2 About the Status LEDs).

3) The operator uses the host user interface (for example, a point of sale) to finalize a transaction

amount, then initiates a transaction.

4) The host communicates with the device, and reports to the operator when the device is ready.

5) The operator directs the cardholder in presenting payment.

6) The cardholder interacts with the device to present payment. The following sections provide

additional details about presenting each of the available payment methods.

7) Because the device does not have its own display, the device may send messages to the host

prompting the cardholder to perform certain actions; the host software should process these requests
by displaying the requested messages, and depending on the placement of the host display(s), the
operator may need to relay the messages to the cardholder. For example:

a) If the device can not read the card, it may prompt the cardholder to swipe, insert, or tap again.
b) If the device repeatedly can not read a chip card, it may revert to using the magnetic stripe reader

instead of the chip card slot. This is known as EMV fallback.

8) The device reports the success or failure of the transaction to the host, which should report the results

to the operator.

3.5.2 How to Swipe Magnetic Stripe Cards

Cardholders should swipe magnetic stripe cards in the MSR swipe path, indicated by the bidirectional
MSR swipe symbol shown on the device’s face. The magnetic stripe must face toward and into the
device, as shown in Figure 3-2. Cardholders may swipe in either direction along the path.

3.5.4 How to Tap Contactless Cards / Devices

To tap a contactless card or electronic payment device, cardholders should do the following:

1) If the cardholder is using an electronic payment device, such as a smart phone, make sure the

payment device has NFC turned On and has a payment app configured to process transactions. For
details, see the documentation provided by the smart phone manufacturer and payment app publisher.

2) Wait until the device’s General Status LED lights solid green, indicating it is ready for a tap.

3) Tap the card or electronic payment device on the contactless landing zone, indicated by the EMVCo

Contactless Indicator symbol on the device’s face (see Figure 3-4).

4) Wait for the four Status LEDs to light green and for the device to beep. Because each smart phone

model may have its NFC antenna placed differently, the ideal tap position may vary by make and
model. For example, Samsung users may need to center the phone on the contactless landing zone,
while Apple users may need to tap the top of the phone on the contactless landing zone.

5) Remove the card or electronic payment device from the contactless landing zone.

4 - Maintenance

To avoid damaging the read head, only clean the card path with approved cleaning cards.
DO NOT use liquid cleaning products or insert any other objects into the device.

4 Maintenance

Periodic cleaning of tDynamo’s exterior may be required. To clean the outside of tDynamo, wipe it down
with a soft, damp, lint-free cloth and then wipe it dry.

MagTek’s double-sided cleaning card 96700004 is designed to clean the magnetic read head in the MSR
swipe path and the contact pins inside all chip card contact readers. Keeping both of these components
clean is essential to the device’s functioning. MagTek recommends swiping and inserting a cleaning card
once per week to avoid credit card misreads.

5 - Developing Custom Software

5 Developing Custom Software

Custom software uses the same underlying device command set for all tDynamo connection types (USB
or Bluetooth LE). The device commands are wrapped differently depending on the physical connection
type and the device’s configuration. The following sections give high-level information about
communicating with the device via the various physical connection types in various software
development frameworks, and provide pointers to select API references and sample code.

5.1 USB-Based Custom Software

MagTek produces software development kits (SDKs) with API libraries that provide higher-level
functions wrapped around HID USB communication protocols. These libraries simplify the development
of custom applications that use tDynamo, and include an SDK for the Microsoft .NET Framework, and an
SDK for non-managed Windows executable images, such as.exe or DLL files.

In addition to the SDK API libraries, custom software on any operating system can communicate directly
with the device using native USB libraries and protocols.

If you are developing a point-of-sale (POS) application for Windows, you might also consider using the
service objects for .NET POS (UPOS 1.12), available from Microsoft.

5.2 Bluetooth LE-based Custom Software and Apps

When tDynamo is connected via Bluetooth LE to a host with Bluetooth 4.0 hardware that supports
Bluetooth LE, the device acts as a server/peripheral, and the host acts as a client/central. The custom
software wraps commands in simple Get/Set wrappers, and should use whatever Bluetooth LE library is
appropriate for the chosen software development framework. For example, iOS custom apps use Apple’s
CoreBluetooth Framework, for which sample code is available in the form of Apple’s Temperature
Sensor app; see

https://developer.apple.com/library/IOS/samplecode/TemperatureSensor/Introduction/Intro.html.

5.3 For More Information
