Description
Contactless Test Station III (CTSIII) is able to emulate Near Field Communication (NFC) reader and communicate with a device acting as an NFC listening device such as:
- banking smartcard
- transportation ticket
- NFC enabled smartwatch
- NFC enabled smartphone
CTSIII supports common NFC communication protocols such as:
- ISO 144443 type A or B at all data rates
- Felica at 212 and 424 kbits/s
- ISO 15693 (Vicinity) all data rates and all modes
- Mifare Classic / Ultralight / Ultralight C
End-user may want to build test scenarios and analyze the communication between CTSIII and a device acting as a card for several reasons:
- build simple communication script and analyze device under test answers
- for debugging purposes
- build a script and test it within MPManager before implementing a test application to do the same or more thanks to MPuLib communication dll and libraries
- perform specific measurements or tests and compare the results with ISO, EMVCo or NFC Forum test specifications.
In this example, an EMVCo Type B Reader Emulation sequencer script will be used to communicate with a Type B Visa banking card.
CTSIII includes a sequencer, which will sequentially execute a list of actions.
Compare to a high-level reader emulation script where there are back and forth communications between the computer on which one MPManager is running and the CTSIII controlled by the same computer, the CTSIII sequencer generates an embedded application containing the scenario to execute.
This allows very tight timings control.
For example, the end-user can fully control the TR2 timing between PICC and PCD (Proximity Integrated Circuit Card - Proximity Coupling Device).
TR2 is the delay between PICC End Of Frame start and PCD Start Of Frame start.
The scenario is compiled when calling the Execute Reader Sequence command.
Note that it will cause a delay due to the compilation time.
How to Use
CTSIII is delivered with an NFC simulation antenna (P/N 786703-01).
The antenna is used to perform continuous and successive exchanges with an NFC device, using either MPManager scripting and test functions or a user program.
- 1: Analog In (pickup coil, card emulation)
- 2: Multi-purpose HDMI connector
- 3: Tx/Rx connector (Reader emulation)
- 4: Vdc connector (external VDC measurement)
- 5: Card emulation antenna tuning
- 6: Reader emulation antenna tuning
- 7: LED indicator
- Green: PCD mode enabled (Proximity Coupling Device mode stands for Reader emulation mode)
- Blue: PICC mode enabled (Proximity Integrated Circuit Card mode stands for Card Emulation mode)
- 8: Tx and Rx coil
Perform the following connections between the antenna and CTSIII:
| Antenna connector | CTS3 connector |
|---|---|
| TCL3 HDMI | AUX 1 HDMI |
| Analog In SMA | ANALOG IN SMA, using the provided SMA low-pass filter (P/N 773919-01) if configured in 50 Ω |
| Tx/Rx SMA | TX/RX SMA |
Download the ReaderEmulation_Sequencer_Type_B script and video in the attachment.
Power on CTSIII and open MPManager 3.9.0 (or above).
Position a Type B Visa banking card on top of the PICC-PCD simulation antenna.
Connect the CTSIII and like in the video, open the ReaderEmulation_Sequencer_Type_B script in the script editor of MPManager UI
and execute the script.
End-user has access to the execution log of the sequencer script where the success of the execution of the sequence can be checked.
Note that the sequence is pre-compiled before being executed to avoid compilation delay.
The TR2 delay - delay between PICC EOF start and PCD SOF.- is programmable and applied with high accuracy.
In the viewer tab of MPManager, the end-user gets access to the *.mplog trace and can navigate through it to analyze the communication
between the CTSIII and the card under test.
Note that NI proposes a large range of automatized conformance test solutions that are certified for EMVCo or NFC Forum testing, on top of CTSIII.
Especially, EMVCo or NFC Forum digital test solutions for listening devices include thousands of tests that have been implemented with the sequencer.
