Product Usage Instructions

Getting Started

Powering the POS DK

The POS DK requires a power supply between UDCmin = 4.7 and UDCmax = 5.3 V. This can be provided in two ways:

• Use the USB connector to connect e.g. to a PC (only power-supply, no data connection implemented)
• Use the 2.5mm jack with external power supply.

Do not supply the POS DK with a voltage higher than 5.3 V as it can potentially damage the POS DK. A supply voltage below 4.7 V might lead to improper functionality.
For details about the power-supply please refer to AN11270 “Hardware Design Guide for POS Development Kit”.
The power consumption of the POS DK can reach up to 250-300 mA when generating the RF field.
Once powered on, the POS DK displays a welcome message. As soon as a key is pressed the main menu will be displayed as shown in Fig 2.
The items at the menu and the consequent items in the sub-menus can be accessed by pressing the relevant key at the pin pad.

Showcases

The POS DK comes with a number of showcases which allow an easy demonstration of its capabilities and features:

1. Showcase “Payment”
2. Showcase “Closed Loop Payment”
3. Showcase “Payment System Environment”
4. Showcase “P2P Communication”

In order to leave a showcase during processing (e.g. during card polling), just press the button ‘#’. This will cancel the current step and go back to the main menu.
Payment
For demonstrating the Payment showcase you need the MIFARE DESFire Card, included in the POS package. Please note that this case does not show any secure communication.
First the card has to be initialized with the according payment application as well as an initial credit:

1. Power on the POS DK.
2. Press any key. The INFO menu appears.
3. Press key ‘2’ to select the INFORMATION sub-menu.
4. Press key ‘3’ to select the RESET CARD sub-menu. ‘Present card’ is displayed
5. Put the MIFARE DESFire card on the antenna of the reader in order to create a payment application on the card. By doing this an initial amount of 500.00 credits is also stored on the card which can be consumed during the payment showcase. After this procedure the message “RESET SUCCESS” is displayed.

This procedure can be repeated at any time to reset the amount of credits to 500.00. By pressing any key, the main menu will be shown again.
Now the actual payment showcase can be shown:

1. Press key ‘1’ to start the payment application.

2. Now enter the amount which shall be debited from the card and confirm with ‘*’.

3. Put the card on the antenna of the reader.
   If “DEBIT SUCCESS” is displayed, the previously inserted amount is debited from the credits on the card. If “DEBIT ERROR” is displayed the entered value was higher than the amount of credits on the card.

4. By pressing any key, the main menu will be shown again.

The remaining amount stored on the card can be checked by following procedure:

1. Press key ‘2’ to select the INFORMATION sub-menu.
2. Press key ‘2’ to select the CARD INFO sub-menu.
3. Put the MIFARE DESFire Card on the antenna of the reader. As shown in Fig 7 ‘NXP DESFire NoAuth’ and the remaining value is now displayed.

Closed Loop Payment
For demonstrating the Closed Loop Payment showcase you need the MIFARE DESFire Card, included in the POS package, as well as a MIFARE SAM V2.6 [12] which is available separately.
This showcase has a similar workflow as described in section 2.2.1 but this time the communication is secured by the SAM.
Therefore plug in the SAM into one of the SAM Slots and power up or reset the reader. Then proceed as described in section 2.2.1.
During the reset of the card, an application with restricted access rights is stored on the card. When calling the CARD INFO sub-menu the text “NXP DESFire Auth” is displayed. Payment System Environment
This showcase demonstrates how to read out basic information from one of the cards provided with this development kit (MIFARE DESFire EV1 and JCOP dual- interface)

1. Power on the POS DK
2. Press any key. The INFO menu appears
3. Press key ‘2’ to select the INFORMATION sub-menu
4. Press key ‘2’ to select the CARD INFO sub-menu you are asked to present the card.
5. Put either one of the cards on the antenna of the contactless reader or put the JCOP card in contact reader. In the second case consider the correct orientation of the card: contact-interfaces to the front and upside
6. You can ether present the card to the antenna of the reader or put it into the card slot. In the second case please keep in mind the slot in direction. (Chip connector first and up)

The display now shows the name of the detected application. In this case it is ‘POS RD Banking Card’.
P2P Communication
This showcase demonstrates how to perform peer-to-peer communication with an NFC enabled mobile phone. This can be used for couponing applications, for example.

1. In case a NFC mobile phone with Android 2.3 is used, it is required to start an application and share a tag application. Give also a name for this tag e.g. “My NFC tag”.
2. Power on the POS DK.
3. Press any key. The INFO menu appears.
4. Press key ‘2’ to select the INFORMATION sub-menu.
5. Press key ‘2’ again to reach the CARD INFO Sub-menu.
6. The message ‘Present card’ is displayed. The POS DK now tries to detect a tag in the field.
7. Put the mobile phone over the antenna of the POS DK
8. A peer-to-peer communication is performed between the POS DK and the mobile phone.
9. Once the communication is performed, the POS DK displays the message: ‘NFC mobile detected’. At the mobile phone, the message ‘New tag collected’, ‘NXP POS Reference Design Payment Coupon ID’ is displayed.

Scope
The purpose of this document is to provide a guideline to aid in the first operation of the OM5597 RD2663 Point of Sales Development Kit (further referenced to as POS DK).

General Description

The POS DK can be used to demonstrate, evaluate and adapt the simple implementation of NXP’s devices in Point of Sales terminals.
Both contactless and contact applications can easily be evaluated. This development kit is EMV level1 digital and analog certified and therefore an ideal starting point to develop specific POS terminals based on NXP components.
The design embeds all the required hardware and software for the following interfaces:

• EMVCo compliant contactless smart cards based on RC663,
• EMVCo compliant contact smart cards based on TDA8026,
• Up to four secure access modules (SAMs) via TDA8026.

The user interface is composed of a color LCD display and a pin pad.
The default hardware interface is RS-232, which is used for code uploading and debugging. However, a USB 2.0 full speed connector is also offered but not implemented in the default software.

3. Hidden Menu Functions

The RD2663 POS DK is compliant to EMV Level1 digital and analog. To facilitate the certification of your POS DK the necessary functionality for the certification process is already included. This section shows how to select these features from a hidden menu.
Within this hidden menu the POS software offers several types of testing functionality:

1. A EMV contactless loopback function,
2. A EMV contact loopback function
3. A NFC P2P loopback function
4. A NFC P2P data exchange function.
5. RF Settings (low level test function)

The first four test functions can be started and used from the POS DK without using COMCOM. However, there is debug information available when using ComCom.
The RF Settings functions require the use of ComCom.

Enabling Hidden Menu

To show the hidden menu, proceed as follows:

1. Power On the POS DK 2.
2. Start the console application ‘ComCom’ [9] on your PC.3. Select the COM port number to be used by pressing the according key (1 – 9). Steps 2-4 are only relevant if you also want to access the hidden remote menu.
3. Select the baud rate 115200 bauds by pressing the letter ‘c’.
4. Press ‘a’ to open the COM port.
5. Press key ‘*’ twice.

This will bring up the hidden menu as shown in Fig. 12 to either select one of the loopback options or access the hidden remote menu from ComCom.

• EMV Loopback CL Function
  Selecting this option will start a RF polling loop alternating between type A and type B. You can use this for EMV Contactless verification as well as simply testing the effects of analog circuitry changes.

• EMV Loopback CT Function
  Starts a polling loop on the contact interface slot.

• NFC P2P Loopback Function
  Starts a P2P loopback via LLCP. Every frame received from a peer device will be echoed by the POS

• NFC P2OP Data Exchange
  First implementation step of the P2P loopback needed for NFC Forum certification test.

RF Settings

Selecting ‘5. RF SETTINGS’ brings up the hidden remote menu in the ComCom application. It allows to directly access certain low level RF functions for testing. From here simply choose a menu entry by pressing the corresponding key.

• Config Default RF Type A
  Loads the internally preconfigured register settings for the ISO 14443 Type A protocol.

• Config Default RF Type B
  Loads the internally preconfigured register settings for the ISO 14443 Type B protocol.

• 3.2.3 Carrier on
  Enables continuous unmodulated carrier output for e.g. ISO 14443 or EMVCo standard power tests

• Carrier off
  Disables continuous unmodulated carrier output.

• Polling WUPA WUPB
  Starts a RF polling for both ISO 14443 Type A and Type B cards using the Wakeup commands. Previous register settings will be overridden.

• RF Reset
  Enables the unmodulated carrier and creates an off-pulse of approx. 8 µs. The carrier will always be enabled regardless of the previous state and will stay on afterwards.

• WakeupA
  Sends a single ISO 14443 Type A Wakeup (WUPA) command. Note that the reader has to be explicitly configured to perform this action, using menu option ‘a’ to load the necessary settings.

• WakeupB
  Sends a single ISO 14443 Type B Wakeup (WUPB) command. Note that the reader has to be explicitly configured to perform this action, using menu option ‘b’ to load the necessary settings.

• RATS
  Directly sends a single Request Answer To Select command. Please note that you have to manually load the configuration settings for ISO14443 Type A before using this option.

• ATTRIB
  Directly sends a single ATTRIB command. As for the RATS command, you have to manually configure the reader for ISO 14443 Type B protocol. Again, use menu option ‘b’ to do so.

• Test with Validation Cards
  Starts a continuous polling sequence for use with the official EMVCo validation cards.

• Display Registers
  Displays a register dump from 0x00 to 0x57 in the format “register: value” separated by commas.

• Write Registers
  Allows you to change the value of a given register. This is useful when fine- tuning certain settings as for example the threshold.
