1 - Introduction

1.2 Protection for All Points Within the Payment Infrastructure

DynaPro Mini exemplifies engineered design and delivers a PIN encryption device that combines best
practices for mobility and security. The DynaPro Mini uses the MagneSafe Security Architecture (MSA)
and is built for durability.

In addition to meeting the requirements established by PCI PTS v3.x, which incorporates secure reading
and exchange of data (SRED) features, DynaPro Mini uses the MagneSafe Security Architecture
(MSA), a digital identification and authentication architecture that safeguards consumers and their
personal data. Designed to exceed PCI regulations, MSA leverages strong encryption, secure
tokenization, counterfeit detection, tamper recognition, data relevance and integrity, and dynamic digital
transaction signatures, which together validate and protect the entire transaction and each of its
components.

A key feature of MSA is MagnePrint card authentication, a patented, proven technology which reliably
identifies counterfeit credit cards, debit cards, gift cards, ATM cards and ID cards at the point of swipe,
before fraud occurs.

MSA's multi-layer security provides unmatched protection and flexibility for safer online transactions.

1.2.1 Security and Ease of Integration by Design

The MagneSafe Security Architecture also secures clear text card data. DynaPro Mini uses a 32-bit
secure processor which incorporates flexible data formatting and masking capabilities for compatibility
with existing software and payment applications, eliminating the need for recertification.

DynaPro Mini supports Device Authentication so the retailer, processor, and acquirer have the
confidence of knowing that a rogue reader has not been substituted, and provides transparency to the
processor, acquirer, or ISO if the device is changed. It also supports Mutual Authentication through a
secure challenge/response sequence, which eliminates both the potential of being redirected to an
illegitimate site and the ability to substitute a compromised PIN encryption device.

1.2.2 Read Head Security Features

DynaPro Mini contains a MagneSafe card reader that encrypts card data at the point of swipe to
safeguard personal information encoded on the magnetic stripe. The reader incorporates MagTek’s 3­track encrypting IntelliHead, a magnetic read head with encapsulated and securely-potted electronics that
reads, decodes, and encrypts card data within the head, eliminating the chance of intercepting clear text
data. This secures the magnetic stripe data at the earliest point in the transaction chain—the initial swipe.

DynaPro Mini’s data encryption scheme uses the industry standard TDEA (3DES) algorithm and
DUKPT key management, which offers merchants, processors, issuers, and acquirers the flexibility to

manage decryption services themselves or to outsource, thereby avoiding the risk imposed by unproven,
proprietary encryption algorithms.

In addition, as a card is swiped through the reader, through the use of MagnePrint technology the card
can be authenticated immediately, either by Magensa or by another system, to determine whether the card
is counterfeit or has been altered.

The card reader is capable of reading any ISO or AAMVA encoded magnetic stripe data, and includes an
EMV chip card (ICC) reader on the front of the device under the keypad.

1 - Introduction

1.2.3 Tamper Responsiveness

The DynaPro Mini enclosure and its associated electronics have been designed to form a Tamper­Responsive Secure Cryptographic Device (SCD). The covers are securely attached and incorporate

sensing circuits to detect any attempts to open the unit. Internal spaces within DynaPro Mini have been
minimized to reduce the possibility of unauthorized modifications.

In addition, any attempt to penetrate or modify the device electronically will cause the unit to
permanently erase its stored encryption keys, after which the device will cease to function.

1.2.4 Liquid Crystal Display

The Liquid Crystal Display (LCD) is a 128 x 32 pixel array capable of showing static or animated
messages. Animation includes horizontal scrolling for longer prompt text, and animations on the Swipe

Card and Insert Card pages.

1.2.5 10-Digit Numeric Pad

During normal operation, cardholders use the device’s numeric keypad to enter PINs. An audible tone
provides feedback when entering the PIN digits. There are three additional function keys cardholders
may press during a transaction:

 Cardholders can press the green ENTER (“OK”) key to indicate they have finished their input.
 Cardholders can press the yellow BACKSPACE (“Correction”) key to clear any entered data and

continue the current operation.

 Cardholders can press the red CANCEL (“X”) key to halt the current operation. Depending on the

context, it may cancel the entire transaction.

 Cardholders can press the Up Arrow and Down Arrow keys to scroll display content when required.

1.2.6 Low-Power Standby Mode

When the communication channel (such as the USB bus) goes into suspend mode, or when the device is
disconnected from a host and power source, DynaPro Mini enters a low-power standby mode. Any
current transactions are terminated and all caches are flushed. The device resumes normal operation
when the connection resumes normal operation.

1 - Introduction

1.4 About Solution Planning

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

device with a USB port or with Bluetooth 4.0 hardware that supports Bluetooth LE. When planning,
include any additional support or devices required by the host and DynaPro Mini, such as physical
locations, mounting, power connections, and charging stations.

 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.

 Determine how DynaPro Mini will be physically presented to the cardholder.
 Select which connection type the solution will use. DynaPro Mini has a Bluetooth LE transceiver

and a Micro-USB connector.

 Determine how DynaPro Mini should be configured, and specify that when you order devices.
 Determine the charging schedule(s) and location(s). For example, in high-traffic mission-critical

solutions, it may be most appropriate to keep multiple devices charging for fast swap-out.

1.5 About Terminology

In this document, DynaPro Mini 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 and Mac 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.

2 - Handling and Storage

Proper handling of the device throughout delivery, assembly, shipping, installation, usage,
and maintenance is very important. Not following the guidelines in this document could
damage the device, render it inoperable, and/or violate the conditions of the warranty.

2 Handling and Storage

2.1 Handling to Avoid Damage

Upon receiving the device, inspect it to make sure it originated from an authentic source and has not been
tampered with.

From device delivery through assembly, shipping, installation, usage, and maintenance, the device must
not be exposed to conditions outside the ratings in Appendix A Technical Specifications.

If the device is exposed to cold temperatures, adjust it to warmer temperatures gradually to avoid
condensation, which can interfere with the operation of the device or cause permanent damage.

Do not drop or shake the device.
For information about ongoing maintenance of the device, such as cleaning, see section 5 Maintenance.

2.2 Handling to Avoid Accidental Tamper

This device implements active tamper detection, which uses a small amount of electricity even when the
device is completely powered off. The device ships with the battery charged to approximately 60%,
which provides a shelf life of at least 6 months, and up to a year. Storage conditions (such as storage
above 77°F / 25°C) strongly affect this duration. If the rechargeable battery is allowed to completely
discharge, the device’s tamper detection feature uses the device’s non-rechargeable backup battery. If
both batteries are allowed to completely discharge, the device interprets this as tampering.

Upon detecting tampering, the device locks down and must be returned to the manufacturer to reset. To
avoid accidental tamper events, follow these precautions:

 Charge the device for 12 hours immediately upon receipt to extend its shelf life.
 Before storing the device, make sure the battery is charged to at least 40%.
 Before storing the device, power it OFF by activating Airplane Mode (wireless not advertising). See

section 4.2.3 How to Turn Bluetooth LE Advertising On and Off.

 When stored, recharge the device for 12 hours at least every 6 months.
 Do not drop or shake the device.
 Do not attempt to disassemble the device.
 Do not expose the device to excessive heat or cold (see Appendix A Technical Specifications).

3 - Installation

3 Installation

Installing DynaPro Mini is a straightforward process; the acquirer configures the Certificate Authority,
public keys, terminal and 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 solutions that incorporate DynaPro Mini, including host software,
connecting the device, and charging the device.

3.1 About Software

In any solution, DynaPro Mini is connected to a host, which must have software installed that knows how
to communicate with the device, and which is capable of processing transactions. To set up the host to
work with DynaPro Mini, follow the installation and configuration instructions provided by the vendor of
the host or the host software.

3.2 About Connecting DynaPro Mini

The following sections provide steps for connecting DynaPro Mini to a host via the various available
physical connection types.

3.2.1 How to Connect DynaPro Mini to a Host via USB

To connect DynaPro Mini to a host computer or charger using the Micro-USB port, follow these steps:

1) Make sure the host is powered off.

2) Connect the small end of the USB cable to DynaPro Mini as shown in Figure 3-1.

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

4) Power on the host computer.

Figure 3-1 - Connecting DynaPro Mini to a Computer

3.2.2 How to Connect DynaPro Mini to a Host via Bluetooth LE

To connect DynaPro Mini with Bluetooth LE to a host that has Bluetooth 4.0 hardware and supports
Bluetooth LE:

1) On the host, install and configure the software you intend to use with DynaPro Mini. If you do not

yet have that software, you can download a tool from the App Store called “Light Blue,” which
provides functions to detect the device, connect to the device, and view the device’s services and
characteristics. See https://itunes.apple.com/us/app/lightblue/id639944780.

2) Make sure the device is powered on and advertising by briefly pressing and releasing the power

button or connecting the device to USB power. Note that it is not always necessary to explicitly turn

DynaPro Mini| PIN Encryption Device | Installation and Operation Manual

Page 14 of 28 (D99875642-13)

3 - Installation

on the device before using it; if the device is not powered on but is still advertising (not in Airplane
Mode), it starts powering on when the host establishes a connection.

3) Make sure the device’s battery is adequately charged.

4) Use the host software to scan for Bluetooth devices, and select the device you want to pair to.

5) If the device was not powered on before the host connected, it starts powering on when the host

establishes a connection. The power-on sequence takes about 10 seconds.

6) When prompted, enter the device’s passkey. The default passkey is 000000.

7) The device stays powered on until the host terminates the Bluetooth LE connection, or until an

operator or cardholder powers it off using the power button. Powering off causes the device to
terminate the Bluetooth LE connection. To conserve power, always power off the device when it is
not in use. You can then explicitly power on the device using the power button.

4 - Operation

4 Operation

4.1 Overview

When DynaPro Mini is ready to begin a new transaction, it shows Welcome on its display.

Figure 4-1 - Example of Welcome Screen (Ready for a New Transaction)

During normal operation, an operator initiates a transaction from the host, and the cardholder enters data
on DynaPro Mini’s keypad in response to prompts on its display. Transaction types depend on the host
software, and may include new accounts, teller window applications, checking, savings, mortgages, retail
transactions, or any other option where there is interaction between the cardholder and the operator.

After the operator initiates the transaction, the device prompts the cardholder to insert or swipe a card. If
the device can not read the card data, the device may request the cardholder repeat the action, or request
the cardholder use the magnetic stripe reader instead of the chip card insertion slot, or may ask the
cardholder to enter card data manually. The device may also prompt the cardholder to identify the card
type, such as debit or credit. If the transaction requires a PIN (such as in banking or debit card
transactions), the device prompts the cardholder to enter one. In the case of an EMV transaction with a
successful chip read, DynaPro Mini uses the transaction amount and the chip card’s on-chip risk
management to decide whether to process the transaction offline or require online approval.

A typical transaction sequence looks like this:

4.2 Power Management

4.2.1 About Power

This device incorporates a built-in Lithium-ion rechargeable battery, which requires very little
maintenance. It is not subject to “charge memory” and therefore does not require deep discharge cycles
to restore its charge capacity like many other battery technologies.

When properly powered through its USB port, the device powers on automatically, remains powered on,
and draws power both for operation and for recharging the battery (see section 4.2.2 How to Charge the
Battery). While charging, the device consumes more power from the USB connection than when the
battery is fully charged. The device stops charging the battery when it determines it is optimally full, to
prevent overcharging.

If the device is not connected to USB power, or if the USB connection does not provide enough power,
the device powers itself using the rechargeable battery. When the battery discharges to a critically low
level, the device powers down automatically. In this state, the device continues to power its active tamper
detection circuitry using the device’s non-rechargeable backup battery. If both batteries are allowed to
completely discharge, tamper detection engages, and the device must be returned to the manufacturer to
reset. To minimize battery drain and prevent this from occurring:

 When charging, make sure the device is receiving enough power from the USB connection (battery

level should increase even when device is in use).

 Power the device OFF when not in use (see section 4.2.3 How to Turn Bluetooth LE Advertising

On and Off).

The device’s rechargeable battery is designed to last hundreds of charging cycles, but with time and / or

with use, its charge capacity will naturally degrade. To maintain the battery’s charge capacity as much as

possible, follow these guidelines:
 Do not discharge the battery to 0%. Create a charging schedule that recharges the battery well before

it is fully depleted.

 Store the device at the lowest reasonable temperatures within its specified storage temperature range

(see Appendix A Technical Specifications; below 77°F / 25°C is optimal). Temperature is the most
critical factor in extending battery life.

 Store the device with the battery charged to less than 100% (40% is optimal).

4 - Operation

4.2.2 How to Charge the Battery

When the battery is discharged to a critical level, the device shows a Please Recharge warning message
on the display.

Figure 4-2 - "Please Recharge" Warning

The device’s battery must be periodically recharged by connecting it to either a USB port or stand-alone
power supply. The device requires a USB connection that can provide at least 2A @ 5V. A full recharge
cycle for a completely drained battery takes approximately 5 hours.

4.2.3 How to Turn Bluetooth LE Advertising On and Off

In its default configuration, the device’s Bluetooth LE module can be toggled between advertising and not
advertising to save power or to stop radio emissions for airline travel. The device’s processor and display
also power down when it is not advertising. This state is known as Airplane Mode, and can also be
considered the device’s “Off” state. Operators can toggle Airplane Mode as follows:

 To Turn Airplane Mode On: If the device is advertising, press and hold the power button for 7

seconds or longer to reset the Bluetooth LE module and turn advertising off. The device also resets to
this state if the battery completely discharges.

 To Turn Airplane Mode Off: If the device is not advertising, briefly press and release the power

button or connect the device to USB power to turn advertising on.

For information about reconfiguring the device to behave differently from defaults, see the references
provided in section 6 Developing Custom Software.

4.3 Card Reading

4.3.1 How to Swipe Magnetic Stripe Cards

To swipe a card with a magnetic stripe, cardholders should wait until the appropriate prompt appears on
the display (see Figure 4-3 for an example), then swipe the card with the magnetic stripe facing away
from DynaPro Mini’s keypad as shown in Figure 4-4. If the device can not read the card’s magnetic
stripe data, the device may prompt the cardholder to swipe the card again.

4.3.2 How to Use Contact Chip Cards

To use a contact chip card, cardholders should wait until the appropriate prompt appears on the display
and the LED on the front of the device turns on, then insert the card as follows:

1) Locate the slot on the front of the device shown in Figure 4-5.

2) Orient the chip card so the chip faces the ceiling and toward the slot.

3) Insert the chip card into the slot, then push gently on the card until it stops. There should not be any

substantial resistance until the chip card is fully inserted.

If the device can not communicate with the chip card, it may prompt the cardholder to insert the card
again, or to use the magnetic stripe reader, or to enter card data manually.

4.3.3 How to Enter Card Information Manually

If the swiped or inserted card is damaged or unreadable, DynaPro Mini may prompt the cardholder to
enter card data manually, as shown in Figure 4-6. During manual entry, the device expects the account
number to be between 16 and 19 digits long, the expiration date to be 4 digits long, and the card
verification code (generally found on the rear of the card for MasterCard and Visa, or the front of the card
for American Express) to be 3-4 digits long.

Figure 4-6 - Example of User Screen to Manually Enter Card Data

4.3.4 How to Select the Card Type

In a retail setting, the transaction might require the cardholder to select the card type (e.g. “Debit or
Credit”). In the following example, the application prompts the cardholder to press a number on the

keypad to select Credit or Debit (see Figure 4-7).

4.4 How to Enter PINs

When PIN entry is required, the display prompts the cardholder to enter one (see Figure 4-8) as required
by the financial institution. The device expects the PIN to be between 4 and 12 digits long. After
entering the PIN, the cardholder must press the ENTER button.

.

Figure 4-8 - Example of User Screen to Enter PIN

If the double PIN entry option is enabled, the display prompts the cardholder to enter the PIN a second
time. The process for re-entry is identical to the process for the first entry.

4.5 How to Verify the Transaction Amount

In a retail setting when the customer selects “Credit” they are then prompted to verify the amount of the
transaction. The customer can select “Yes “or “No” as shown in Figure 4-9.

Code

Description

A

An offline code beginning with "A" indicates the device is awaiting authentication. This
is a normal condition when a device is configured to require authentication (security level

4). Authentication by the host is required to return it to the Welcome screen.

C

An offline code beginning with "C" indicates the device is missing a certificate. MagTek
recommends repairing or replacing the device.

H

An offline code beginning with "H" indicates a hardware problem. MagTek recommends
repairing or replacing the device.

K

An offline code beginning with "K" indicates a problem with either the magnetic stripe
reader or PIN key. If the device is new, it is likely it has not been loaded with a PIN Key,
and should be returned to the supplier for key loading. If a K-code appears after the
device has been deployed and used for a long period of time, the K-code indicates one or
both DUKPT keys have been exhausted. MagTek recommends contacting the supplier for
a replacement.

S

An offline code beginning with "S" indicates a security element failure. This code can be
triggered by severe handling of the device or strong interference by a nearby source of
electromagnetic (EMF) interference. Try moving the device away from any suspected
EMF source; if the error persists, the device should be repaired or replaced.

4.6 About Status Codes

The Device Offline screen indicates that the device is not ready for normal operation. There is also a
code in the lower right corner that can help explain the cause of the offline state. Codes that start with H,
S, C, or K indicate the problem requires the device be returned to the supplier for service or replacement.

6 - Developing Custom Software

6 Developing Custom Software

Custom software uses the same underlying device command set for all DynaPro Mini connection types
(USB HID or Bluetooth LE). The device commands are wrapped differently depending on the connector.
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.

6.1 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 DynaPro Mini, 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 the HID 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.

6.2 Bluetooth LE-based Custom Software and Apps

When DynaPro Mini 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.
