2  How the VTAP100 works
With the VTAP100 OEM module connected to a PC, simply tap your smartphone against the
VTAP. Your mobile NFC pass will be read and data sent to the connected PC.
Of course, the data can only be read if your phone contains a mobile NFC pass, which has
been issued in connection with the Merchant ID(s)/Collector ID(s) and key(s) that are known
to the VTAP. The unit comes with default values, so that you can test Default operation on
factory settings before you begin customising any settings.
When the VTAP100 OEM module is connected to a computer it appears as a generic mass
storage device (like a memory stick). To configure your VTAP, you simply edit or create text
files. These will be read automatically, and control the operation of the VTAP. Consult the
VTAP Configuration Guide for more detail.
By default the VTAP is fully upgradable in the field. However, the VTAP can be locked in
software or hardware, before deploying the unit, so that operation is no longer easily
changed.

2.1 Default operation on factory settings
Before anyone changes the configuration from its default, you can confirm that the unit is
working.
These steps demonstrate that the hardware can detect and interact with an OriginPass mobile
NFC pass, which is ready to work with the default configuration of your VTAP100.
1. Obtain an OriginPass from Dot Origin by visiting https://originpass.com/VTAP/ and add it
to Google or Apple Wallet. (You will require a username and password - contact
[email protected] to get these.)
2. Connect the VTAP100 to your PC, using a USB cable.
3. Open a text editor, such as Windows Notepad.
4. When you tap the OriginPass on the VTAP100:
lPass contents will be displayed in the open text editor.
lThe diagnostic LEDs on the VTAP100 PCB will flash together.
lYour smartphone may signal with a buzz or beep.
Note: Some Android phones will only interact if their screen is on, although it does not
need to be unlocked. You may need to enable NFC in the settings for the smartphone.
Note: If the pass detected does not match the key and ID on the VTAP, or is moved away
too quickly to be read, the pass contents displayed will be an 8 digit random hex string,
such as '08E22AC1', different on each presentation. OriginPass contents will be a
consistent string of the type '3~ffymeK9f_mziYtA6~53999301628695~Valued'. The
separator '~' or '|' will depend on your keyboard language settings.
Note: If local security settings prevent or limit the use of removable storage devices, or
the connection of additional keyboards, an administrator may need to alter those
permissions.

3  Mechanical installation
The VTAP100 unit for OEM integration comprises a PCB with an integral antenna.
Figure 3-1 VTAP100 components - v4a Hardware
WARNING: Observe all Safety instructions when installing the VTAP100 PCB.
There is more detailed information in section 3.5 about how to fit the VTAP100 unit inside
the Optional case case, if used.
3.1 Power
Connect the PCB to a PC using only a MicroUSB to USB cable.
The VTAP100 is rated at 5V DC (typ. 110mA, max 150mA) for power over USB.
3.2 Environment
The VTAP100 must be stored and operated under the following conditions:
lAmbient temperature -25 to +70°C (-13 to 158°F)
lHumidity 0 to 95% RH non-condensing
lPressure 86-106kPa

3.3 Mounting points
The PCB has 2.7mm diameter mounting holes for fixing the unit. Either use the 50mm
spaced holes on the snap-off tabs, or remove those tabs and make use of the holes on the
body of the board. If you need to remove the tabs, we recommend carefully following the
perforations provided to avoid damage to the board, using a vice and pliers, or a PCB cutter.
Use 2-4 small nuts and bolts to mount the board securely.
Figure 3-2 VTAP100 PCBmounting holes - v4 Hardware
The user’s smartphone should be able to tap within 10mm of the antenna on the PCB. The
antenna position should be clearly marked and easily accessed, so that users can position
their smartphone appropriately. Be aware that antennas are positioned differently in
different makes of smartphone. Apple iphones often have antennas near the top and
Android phones are more likely to have an antenna in the middle.
CAUTION: Mounting a VTAP board on metal can reduce performance of the VTAP100,
because metal can distort the NFC field. Never allow a metal surface between the
VTAP100 and the user's phone or card. If you have to mount the VTAP100 on metal, you
should ensure the separation is:
lat least 6mm and insert a ferrite sheet between the VTAP100 and the metal surface, or
lat least 25mm separation between the VTAP PCB and the metal, which will be achieved
if the VTAP100 is inserted in a compact case before mounting.

3.4 Optional RS232 connection
The PCB has a special connector J1 (an 8 pin, 2mm pitch header connector) which can be
used to attach a captive cable with a matching crimp housing.
The standard connector fitted to the PCB is a Hirose DF11-8DP-2DSA male header plug
with shroud. The matching crimp housing is the Hirose DF11-8DS-2C.
Figure 3-3 VTAP100 captive power cable or RS232 connection -
v4a Hardware
The connector J1 includes both USB and RS232 signals, as follows:
Pin Function
1 GND
2 USB D+
3 +5V supply
4 USB D-
5 RS232 RXD (input)
6 Reserved (sense input)
7 RS232 TXD (output)
8 Reserved (sense GND)

Figure 3-4 Typical RS232 cable
A typical RS232 cable has the following DB9 female connector pinout:
Pin Function
2 TXD
3 RXD
5 GND
9 +5V supply (if any)
A PC or terminal RS232 connector is usually DTE (data terminating equipment), typically a
male DB9 with transmit (TXD) on pin 3 and receive (RXD) on pin 2. The appropriate
connecting cable is then a DCE (data communications equipment) female DB9. TXD and
RXD pins are swapped between the DCE and DTE devices, so that the transmit pin on one
connects to the receive pin on the other.
The VTAP100 requires a 5V power supply, but not all RS232 devices have 5V on pin 9. Your
options are:
lIf your RS232 connector provides 5V power on pin 9, disconnect the USB cable before
making the serial connection, then power will be provided by J1 (pins 1 and 3) and the
serial cable/host.
lIf your RS232 connector does not provide 5V power on pin 9, retain a USB connection in
addition to the serial connection.
Some serial cables have a separate DC 5.5/2.1mm barrel connector to supply power. In
these cables, typically, the centre pin is +5V and the outer barrel is GND.

3.5 Optional case
The optional compact case for a VTAP100 is 97mm x 49mm and 40mm deep.
Figure 3-5 VTAP100 -CC compact case
You can design and affix your own branded label to the unit. If you need help branding units
do contact [email protected]. We can take your CMYK, vector format images and
design and supply labels manufactured to high standards using an advanced production
method, where the printing is protected by a thick layer of clear plastic, making them
scratchproof, waterproof and UV-proof. Apple guidelines require the standard contactless
logo to be used, and so our standard label template includes this along with a design that
highlights the location of the VTAP antenna, as that is the target location for a user to tap
their phone.
The size of the label recess on a compact case (-CC) is 41mm x 57mm with 2mm radius
rounded corners as shown below.

4  Module integration instructions
The VTAP100 OEM module has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. Operation is subject to the
following two conditions:
(1) This device may not cause harmful interference.
(2) This device must accept any interference received, including interference that may cause
undesired operation
These instructions must be followed to maintain the FCC approval for the VTAP100
OEM module, when it is integrated into a host system.
CAUTION: Changes or modifications made to the VTAP100 OEM module, that have not
been expressly approved by Dot Origin Ltd could void the user's authority to operate the
equipment.
4.1 Applicable FCCrules
The VTAP100 OEM module operates at 13.56MHz and is therefore subject to FCC rules for
radio frequency devices. When a pass is presented to the reader, a person comes within
10mm of the device, so the rules relating to 'portable' transmitters apply.
4.2 Specific operational use conditions
The VTAP100 OEM module must be stored and operated under the following conditions:
lAmbient temperature -25 to +70°C (-13 to 158°F)
lHumidity 0 to 95% RH non-condensing
lPressure 86-106kPa
4.3 RF exposure considerations
This module complies with FCC RF radiation exposure limits set for an uncontrolled
environment. It is expected that VTAP100 OEM modules will be mounted in places that make
it possible for people to come within 10mm of the unit and it is therefore defined by the FCC
as a 'portable' device.
Screened cable should be used, wherever possible, to connect VTAP100 OEM modules to
other devices, to avoid interference from other equipment.
The end-user manual for the host equipment, that contains a VTAP100 OEM module, must
clearly indicate the operating conditions to be observed, so that the user remains in
compliance with current FCC RF exposure guidelines.
VTAP MOBILE WALLET READERS

4.4 Antennas
The VTAP100 OEM module has been tested with its integrated loop antenna, printed on the
PCB. There are no alternative antennas approved for use. If an external antenna is attached,
the new arrangement would require a new FCC approval.
4.5 Label and compliance information
The integrator must attach a label to the new equipment, hosting the VTAP100 OEM module,
which states 'Contains FCC ID: 2A282-VTAP100'.
4.6 Information on test modes
The following test modes are recommended to achieve states of maximum emission levels or
susceptibility in the VTAP100 OEM module:
1. VTAP100 OEM module powered on. Communicating with PC over USB. Continuously
reading tag.
2. VTAP100 OEM module powered on and tag present, but not communicating with external
device.
4.7 Additional testing requirements
The VTAP100 OEM module is only FCC authorised for use in compliance with the specific
FCC transmitter rules listed on the grant. The integrator is responsible for compliance to any
other FCC rules that apply to the host, which are not covered by the modular transmitter
grant of certification.
The final host product, with the VTAP100 OEM module installed, will still require Part 15
Subpart B compliance testing, to evaluate transmission effects when the VTAP100
OEM module and host equipment operate at the same time. Be aware that additional
testing can be required on the final integrated system. We recommend integrators refer to
further advice from the FCC OET Knowledge Base, such as 996369 D04 Module
Integration Guide v02.

5  Hardware lock to disable USB mass storage device
You can lock the VTAP100 so that its firmware and configuration cannot be changed. You can
either do this in software, or simply disable the mass storage device in hardware., which is
described in the VTAP Configuration Guide
A software lock prevents changes but leaves some files visible. A hardware lock means that
the VTAP100 will no longer be detected as a USB mass storage device. (It will still behave as
an HID keyboard device and, if enabled, the virtual COM port will behave as a composite USB
device consisting of HID keyboard and USB virtual COM port.)
You can use a hardware lock provided the jumper labelled LOCK (close to the
MicroUSB connector) remains accessible on a VTAP100 OEM module.
Connect a jumper across LOCK on the PCB to lock the device, preventing firmware or
configuration changes via the mass storage device. (It may still be possible to update the
firmware or configuration via the command interfaces of the virtual COM port or serial ports,
if they are enabled.)
Figure 5-1 Jumper positions on VTAP100 PCB v4a hardware
When you start the VTAP100, the presence of this jumper means the connected PC will not
detect a USB mass storage device. The VTAP100 will only be detected by the PC as a
keyboard (or keyboard and virtual COM port).
At any time you can remove the jumper across LOCK. When you restart the VTAP100, it will
be detected as a USB mass storage device and you will be able to make firmware or
configuration changes again.

6  Disposal
For safety and sustainability, it is the responsibility of the integrator to ensure that when
equipment containing a VTAP100 reaches the end of its life, it is recycled in accordance with
WEEE Regulations within the EU.
VTAP100 (PCB and cables) should not be disposed of in general waste. If you
wish to discard electrical and electronic equipment (EEE), please contact your
supplier for further information.
